La maggior parte delle persone deve dare credito a Benjamin Franklin per aver scoperto l'elettricità


Most people must give credit to Benjamin Franklin for discovering electricity. However, it is also necessary to give some (or a lot) of the credit to electricians too. As also most everything runs on electricity. Briefly, an online electrician service provides these services:

  • Complete, Electrical Service delivery for Commercial as well as Industrial Projects
  • Light Designing and Upgrading
  • Unit Developments
  • Switchboard and Mains fixing and upgrades
  • Industrial and Commercial rewiring
  • Generally finding Fault
  • Connecting TV, Phone and Data Points
  • Testing and Tagging electrical
  • Installing ACs
  • Installing CCTV, MATV and Intercoms

What do electricians do?

Electricians are responsible for installing and maintaining all of the electrical and power systems for homes, businesses, and factories. They have to install and maintain the wiring and control equipment system through which electricity flows. Other than that, they install and maintain large electrical equipment and machines in places like factories and also a wide range of other businesses.

Moreover, electricians also focus on either construction or maintenance, although several are capable of doing both. Electricians who specialize in construction primarily provide the service install wiring systems in factories, businesses, and even new homes. Comparatively, electricians who specialize maintenance are able to fix and upgrade current electrical systems and make repairs to electrical equipment. All electrician services are online to be performing their work, accordingly.

How do electricians work?

Usually, electricians begin their work by analizing blueprints ie technical diagrams that locate the circuits, outlets, load centers, panel boards, and other related equipment. After making sure about which wires and components will go, electricians will carry on to install and connect the wires to either circuit breakers, transformers, outlets, or other components and systems, according to the occurrence of the fault.

Maintenance electrician:

A maintenance electrician repairs or replaces electric wiring and other electronic equipment when it at fault. They quick with their repairs and do it as quickly as possible in order to cause minimal inconvenience. Online maintenance electricians services may also include replacing items such as damaged circuit breakers, fuses, faulty switches, problematic electrical and even electronic components, or wire, to save from further issues.

Electrician for non-commercial use:

Usually, an electrician in large factories does maintenance work which is much more complex. These types of electricians provide services for repairing motors, as well as transformers, generators, and electronic controllers on machine tools and industrial robots. Other than that, they also advise management as to if continuing to use a piece of certain equipment could be life-threatening. While working with more complex electronic devices, they may also consult with electrical engineers, engineering technicians, also line installers and even other repairers, or maybe an industrial machinery mechanic and maintenance worker.

Conclusively, an Electrician service online can also be found to keep both home and office places running and secure. Even if there isn’t any fault, electricians also seasonally inspect all equipment to make sure that they are operating fine and to fix any problems before a breakdown may occur.

Radianti elettrici e rivestimenti per pavimenti

Radianti elettrici e rivestimenti per pavimenti


If the decision of what type radiant heating system to use was left to the floor-coverings, it would choose electric radiant. Eliminating the risk of water / glycol
leaks, standard floor-heights, simple retro-fits, almost unlimited choice of carpet
padding, uniform heat flux, easier installations and superior floor or space
temperature control are only a few of the advantages of electric radiant heat. This
isn’t to say that there aren’t disadvantages of electric radiant, but then I’m a sparky
not a plumber, so I’m here to espouse the benefits and desirable features of electric
radiant heat and its loving relationship with any and all floor-coverings. Oh, wait a
minute, how could I forget, electric systems cost a fraction what hot-water
(hydronic) systems do.

From the simplest of painted concrete to floors to floors that started with linoleum,
added carpet, then converted to imported marble, electric radiant is truly and simply
superior to hydronic radiant and here are the reasons why.

There is no water or glycol – and spilled electrons don’t damage floor-coverings, in
fact, there’s no need to even sweep them up. Seriously, the safety standards and
National Electrical Code keep electrical systems safe. Yes, a cable, mesh or mat can
be damaged by an errant nail or screw, but the worst case scenario is the system
doesn’t work as compared to a penetrated tube of a hydronic system with 100
gallons of water and glycol pumped out on the top level floor of a three floor
custom home.

Built-up floor height for most electric systems is less than ¼ “and some as little 1 /
16 “thick. Most hydronic systems pour 1 ½” of light-weight concrete over the tubes
increasing construction costs and limiting the types of floor-coverings that can be
installed. If you want traditional hard-wood floors, a complex system of sleepers
must be installed to allow for nailing of the wood to the sub-floor.

Retro-fitting carpet over what used to be tile can’t be easily done with hot-water
systems. Changing the R-value (insulating characteristic) of the floor-covering
changes the amount of heat that makes it into the space in hydronic systems, since
they are designed to transfer heat via a temperature difference between the water in
the tube and the floor covering surface, whereas electric systems put out a constant
wattage regardless of the floor-covering insulating characteristics. Floor covering
types can be changed time after time with electric radiant without changing the
heating system.

Hot and Cold Spots or what some-people call spot-heating can be easily
accomplished by installing higher or lower heat-density and adding a simple floor-
sensor to control the temperature. Have you ever noticed how dogs or cats search
for the warmest piece of flooring in a home and sleep there? We added a special tile
floor heated 10 ° warmer for our house pet that became new sleeping
accommodations for Cairo.

Uniform Heat Flux – The harder the floor covering the more noticeable warm or cold
spots become and the layout of the hot-water tubing and the changing temperature
of the water through the loop result in changing floor-temperatures. This doesn’t
happen with electric heat, each foot of cable, or length of mesh or mat generate
exactly the same amount of heat as the next foot making it very easy to maintain a
constant temperature across the floor. If the floor-coverings are going to be
different in one room or one zone, split it into two zones of electric so the desired
temperature can be maintained on each surface. This is easier to do and less costly
for electric than hydronic.

Installation of any product is a concern and any time the cross-trade issues of
installation can be minimized everyone wins. Electric systems don’t require any
mechanical room space so long as they are installed before the floor-covering is
installed you don’t have to do a lot of coordination with the other trades. If you
want to climatize some exotic hardwood flooring from Brazil within the space it’s
unlikely that you’ll have gas to operate your boiler, but it’s very possible that you
can run your electric radiant heat off of temporary power to assist in stabilizing your
wood before installation. Take that example one step further and you realize that
all the other trades on site will appreciate the temperature inside if it’s Leadville,
Colorado in February.

Independent of HVAC – Electric radiant can be the primary heating system, but can
operate very efficiently if you want the bathroom floor 80 ° in June and your husband
has the air-conditioner running throughout the rest of the house. Try doing this
with your 1,000,000 Btu boiler and you’ll regret it when the time comes to pay your
gas or oil bill.

Precise Temperature Control – Adding multiple zones to an electric system costs
only pennies per foot compared to dollars per foot for hot-water. Having as many
zones as you ever anticipate different areas with different floor-coverings is
possible and practical, with the other benefit of precise control of temperature of
every space in the home.

My mother and father used to sit and watch TV (football, basketball, etc.) in a love
seat in their master bedroom and my dad was always cold while my mom was
always hot. I installed a two-zone electric system right underneath the love-seat
split right down the middle with a thermostat for my mom and one for my dad.
Believe it or not, it worked beautifully. My dad’s feet sat on a floor that was 85 °
while my mom’s were on a floor that was 75 °.

Cost – Installation costs of electric radiant is almost always less than any hot-water
installation and the smaller the area to heat the bigger the difference. And here’s
the kicker, if you save a lot of money on your radiant heating system you can spend
every penny of that savings on Imported Italian Marble in your Entry and Master

Pausa vacanza per macchine elettrich

Pausa vacanza per macchine elettrich


Are you overloaded? Have you become a part of the highly stressed
modern working environment? You may need a break – a vacation, a
change in environment, a change of pace …

Similarly, machines can be overloaded too. Those that were
designed for a particular system are often pushed to their limits
when new requirements emerge.

Just like the final straw that breaks the camel’s back, electrical
machines too, can reach their breaking point. If there is no
vacation for them, they will burn.

Fuses and circuit breakers are designed to stop the current in a
circuit before any damage can occur – create a vacation or a break
for them.

A circuit breaker is one of the ways to prevent motors (or other
electrical machines) from burning due to overloading. All
electrical motors produce heat when running. At the time of a
fault, this heat builds up at a much higher rate than it can be
dissipated. This can result in damaged equipment, fire or even

The electrical protective device like the circuit breaker is
designed to de-energize the circuit before this heat level becomes

There are basically 2 means of activating a break – thermally
(heat) or magnetically.

Thermal circuit breakers make use of bimetallic strips that will
bend due to the different expansion rates of each of the metals in
the strip. The bending of the strip will move a tripping mechanism
latch that will then open up the contacts of the circuit breaker.

Because bimetallic strips take time to heat up and bend, this type
of tripping device is used for tripping prolonged overloaded
situations. The setting for breaking the circuit at a particular
overload value can be adjusted.

Magnetic circuit breakers make use of the field strength of
magnetic coils to trip a latch that will then open up the contacts
of the circuit breaker. This method is used for high current
faults, like in a short circuit. This method is designed to trip

A thermal-magnetic circuit breaker incorporates both a thermal
strip and a magnetic coil. This type of circuit breaker is able to
protect against momentary overloads as well as high or short circuit
current faults.

What happens if the circuit breaker is placed in a high temperature
environment? The thermal bimetallic strip bends on high temperature.
In this case, the current is not causing the high temperature in the
bimetallic strip, but the ambient air is! The current may still be
below the safe operating rated value for the motor.

In this case, a compensating bimetallic strip may be incorporated
into the circuit breaker to eliminate this type of error. These
circuit breakers are often used in hot areas like furnace, oven, and
boiler rooms.

Circuit breakers can be reset very quickly, once they have tripped.
Can your break or vacation be reset very quickly too? Don’t reset.
Take a long break!

Until next time …

1. Orientation, layout and positioning of your house on the land

Orientate your living areas to the south side of the house, which receives most of the sun throughout the day (north if you live in the southern hemisphere).

2. Insulation and draught proofing

Make sure your walls, roof and floors are insulated and fill any gaps where draughts might come through.

3. Ventilation

Position doors and windows opposite each other to allow for a cooling breeze to flow through the house when the air cool down in the evening of a hot summers day.

4. Windows

Windows on the south side of the house should be bigger to allow more sun to penetrate the house during the day and windows on the north side smaller to prevent heat lost at night.

5. Landscaping

Position trees and plants to direct a cooling breeze into your house, whiles shading it during summer. Plant trees that shed their leave in winter.

6. Shading

Make sure external shading structures are wide enough to block out the sun in summer, whiles still allowing the low winter sun to enter.

7. Thermal mass

Polished concrete, tile or slate floors and brick walls will absorb the heat throughout the day and release it slowly at night, reducing the need to run expensive heaters. Carpet acts as an insulator and will not retain the heat.

Although it’s far easier to achieve passive solar energy for homes during the planning stage, you can incorporate many of these elements into an established house without spending a great deal of money or time.

It might be as easy as filling in a few gaps, installing an additional window or moving your living area from the chilly north side of the house to the sunny south side …

Hiring a professional electrician can be very expensive and is often the reason why people try doing their own basic electric wiring themselves.

I have seen the good, the bad and the ugly results of these efforts and I have come to the conclusion that basic electrical wiring is not something anyone should do without proper guidance, tools and confidence.

It is so important that before attempting any of these basic electrical wiring projects that people are aware of how dangerous electricity is and how important safety is for you and for your family and family home.

90 percent of the time I recommend hiring a licensed electrician over doing your basic electrical wiring yourself. Not doing this will usually end up costing even more money than before and increase the risk of bringing your family into danger without even knowing your doing it.

But doing your own basic electric wiring really isn’t that hard to do if you “educate” yourself on the topic.

Licensed electricians had to learn the stuff themselves too. So as a ‘do it yourself person’ this isn’t different. There is no escape possible.

You will see that the more you read about it the easier it will become and the more confidence you will get.

Just to give you an idea, here are 3 questions I recently got from people just like you who tried doing their own electric wiring:

Question 1: I installed a grounding probe in your aquarium and every time anyone in the house turns on or off the lights, the fish jump. What’s going on?

A couple of suggestions:

1. (easiest) Pull out that grounding probe and return it from whence you purchased it.

2. Check the wiring on your outlet. You may actually have ‘Neutral’ instead of ‘Ground’.

3. Check the wiring throughout the rest of the house. There are some people out there that insist on doing their own home repairs, yet don’t understand basic electrical wiring.

Outlets are easy to check by getting a $ 7.95 outlet tester from the hardware store. Wired-in appliances, lights, heaters, etc. are tougher.

4. Check all your electrical fixtures to make sure they aren’t leaking some voltage to Ground.

Question 2: What is the NEC? Where can I get a copy?

The NEC is a model electrical code devised and published by the National Fire Protection Association, an insurance industry group. It’s revised every three years.

The 1993 version has been released. You can buy a copy at a decent bookstore, or by calling them directly at 800-344-3555.

The code exists in several versions. There’s the full text, which is fairly incomprehensible. There’s an abridged edition, which has only the sections likely to apply to most houses.

And there’s the NEC Handbook, which contains the “ authorized commentary ” on the code, as well as the full text. That’s the recommended version. Unfortunately, there’s no handbook for the abridged edition. And the full handbook is expensive – US $ 65 plus shipping and handling.

Question 3: Can I do my own wiring? Extra pointers?

In most places, homeowners are allowed to do their own wiring. In some, they’re not. Check with your local electrical inspector. Most places won’t permit you to do wiring on other’s homes for money without a license. Nor are you permitted to do wiring in “commercial” buildings.

Multiple dwellings (eg: duplexes) are usually considered “semi-commercial” or “commercial”. However, many jurisdictions will permit you to work on semi-commercial wiring if you’re supervised by a licensed electrician – if you can find one willing to supervise.

If you do your own wiring, an important point:

Do it NEAT and WELL! What you really want to aim for is a better job than an electrician will do. After all, it’s your own home, and it’s you or your family that might get killed if you make a mistake.

An electrician has time pressures, has the skills and knows the tricks of the trade to do a fast, safe job. In this FAQ we’ve consciously given a few recommendations that are in excess of code, because we feel that it’s reasonable, and will impress the inspector.

The inspector will know that you’re an amateur. You have to earn his trust. The best way of doing this is to spend your time doing as neat a job as possible. Don’t cut corners. Exceed specifications. Otherwise, the inspector may get extremely picky and fault you on the slightest transgressions.

Don’t try to hide anything from the inspector.

Use the proper tools. Ie: don’t use a bread knife to strip wires, or twist wires with your fingers. The inspector won’t like it, and the results won’t be that safe. And it takes longer. And you’re more likely to stick a hunk of 12ga wire through your hand that way.

Don’t handle house wire when it’s very cold (eg: below -10C or 16F). Thermoplastic house wire, especially older types become very brittle.

As you can see, getting the right answers to your questions can make the work a lot easier.

You save time by doing it “the right way” from the first time and you save money because you won’t need to hire an electrician to either do the entire job or to fix your screw-ups.

In any case, no matter what you, be very careful when working on electricity! If needed cut down the entire power of your house just to be sure.

Keep It Safe,

Power tools are one of the greatest conveniences for getting handyman jobs and professional jobs done quickly, but since power tools often run on electricity, it is essential that safety instructions are followed.

Here are a few quick power tool safety tips .

Tip 1 – Always use the correct power tool for the environment.Power tools that are made for outdoor use have better insulation, heavier wiring and a three way grounded plug.

Tip 2 – Keep your power cord tangle free and away from the tool “action” zone.

Tip 3 – If you get any nicks or cuts in the cord, inspect them immediately. If it severe consider replacing the cord. As a last resort use tape to shield it from the elements for minor nicks.

Tip 4 – Inspect the power cord and all connections regularly for signs of breakage.

Tip 5 – Avoid using electric power tools on wet surfaces as water is a good electrical conductor. In combination with other factors – broken cords, machine malfunctions etc, it can put you at risk of shock.

Tip 6 – Never immerse your power tool in water – seems obvious but has to be said.

Tip 7 – Keep your work area clean – dust can ignite from a spark. Avoid using power tools near flammable liquids or gas.

Tip 8 – Follow any specific instructions from the manufacturer.

Ok, so these are some safety tips, nothing beats a safety consciousness and putting safety as a priority when using power tools. So be safe and enjoy your work.

Air Sanders: Dimentica l'elettricità, vai in aria!

Air Sanders: Dimentica l'elettricità, vai in aria!


An air sander is a common air tool often overlooked by most people. If you already have an air compressor to run your impact wrench, you may consider purchasing an air sander instead of an electric model. Your average off the shelf electric sander is fine for little home projects. But if you are really concerned about production and speed, an air sander will blow it away. These tools are also more rugged, versatile and lighter.

The main reason is the power source is your air compressor, not the little electric motor in the sander. This also makes them easier to fit into weird places and hold over your head to reach a ceiling. At the end of the day, an air sander is much kinder to your hands, while delivering more power. They also come in models that are both sanders and buffers. I really recommend one of these if you are a car or boat enthusiast. An air buffer will make quick work of a long wax job on your favorite ski boat. You can then turn around and use the same tool to sand down your kitchen cabinets for painting.

Air sanders are really versatile tools and a great addition to your air tools for your garage compressor. There are also orbital sanders, dual action sanders and palm grip sanders for any application you might run across. It may be time to take a second look at that air compressor stuffed in the garage. They can do a lot more than just fill up tires and run impact wrenches.

Have you ever wondered about the evolution of the stove? This article briefly explains the evolution of fire and the stoves that are now used for cooking fine meals in homes across America every night of the week.

Fire is indeed a very old discovery. It is used for warmth, to heat water for bathing and for cooking meat, vegetable and other food items. It can even be used to make hot drinks. Electric fireplaces are the most recent adaptation of the discovery of fire. When early man first learnt the art of making fire, his life and indeed our lives, changed forever. Early man huddled around the fire to gain warmth and to cook and in many respects fire is not all that different now.

Since this early time, we as a people, have evolved to the point where we now have electric fireplaces and electric stoves meaning that we don’t have to spend hours trying to start and stoke a fire. Rather it is done automatically for us.

The role of fire has changed a lot too. Kitchen stoves have become increasingly popular as they essentially provide the same heating and cooking capabilities as was the case for the cave dwellers all those millions of years ago. Once modern stoves were invented however, the fire became more refined and was split between living room and kitchen, with many abodes having both facilities in their homes.

With the advent of electricity, electric fireplaces and stoves are now at the most advanced they have ever been. For one thing, electric fireplaces don’t require a ventilation system like traditional fireplaces do and stoves have in built ventilation systems and even additional stove top ventilation fans.

Because electric fireplaces and stoves run on electricity, it is easy to be able to control the amount of heat they give off for warming the room or cooking your dinner. All you need to do is just turn the settings up or down according to your needs.

The heat output from electric fireplaces and stoves is much more efficient than wood- burning or gas-burning ones because the output remains constant until such time as you change it or turn it off. With wood burning and gas burning fireplaces and stoves the heat can fluctuate and you have only minimal control. Electric fireplaces and stoves are much easier to maintain and clean as well. You’ll never have to chop up wood or scoop out ash or clear out the chimney. The only thing you’ll have to worry about is wiping out the fireplace at the beginning of each winter or wiping out the stove every couple of weeks to keep it free of spillages.

Ever since Benjamin Franklin went outside with his kite during a thunderstorm, electricity has ruled the world. All you have to do to understand this is to remember what it was like the last time your power went out for an evening. Nothing worked. No computer, no refrigerator and more importantly, no TV. Electricity runs everything important in our lives and when it malfunctions, somebody has to fix it, somebody who knows what they’re doing, that is. Electricity has the power to run things when it works smoothly, but, it can also burn things and kill people if misused. Of all the household accidents in this country, home electrical repairs ranks second in accidents right behind falling off ladders – only home electrical repair accidents are more deadly than falling off ladders.

Good electricians are highly trained individuals with a lot of schooling and practical experience behind them. Before you go sticking your hand into a fuse box, or rewiring the house for power, you have to know a lot about electrical power – the way it moves, how it does what it does, the math and physics behind it and a lot of other things. Everybody feels like a bit of an electrician simply by changing that blown fuse or plugging things in just right or wiring up that complicated TV / VCR / DVD / stereo entertainment center you’ve just bought. You wire it up, plug it in and somehow it all works without any sparks or problems and you feel like you could have been an electrician if you’d really wanted to. Wrong. There is a world of difference between plugging things in and being an electrician.

To begin with the body of mathematics behind electrical work is impressive. Electricity is measured in volts and is a function of voltage, current and resistance – all factors with a complex mathematical relationship. There are laws, not the building codes set in place by municipal governments to insure the safety of houses and commercial buildings, but mathematical laws proven with chalkboards of bizarre looking figures that prove how electricity will function under different circumstances. And there are unions. In fact the Electrical Workers Union (EWU) is one of the strongest unions in America protecting the integrity of the profession from scammers and schemers.
