The codes are concerned with proper size of wire and with insulation. Factors that are considered are the expected load, the frequency of modifications, and the nature of the environment where the wire is used. Homes have small loads, infrequent modifications and a very non-corrosive environment. Commercial establishments are usually in the middle. The load demands are sometimes higher, and modifications are not infrequent. The factory or industrial site has a very high demand. Modifications are frequent, and the environment is often highly unstable.

The electric wiring may be overhead power lines, cable lines, current leads, or interior wiring. Examples of electrical equipment include electric machinery, distribution centers, and control consoles. In the USSR, electrical installation work is usually carried out in two stages.

New appliances come with their own electrical challenges, which is why many people choose to pay for the installation. Yet, if you're a true DIY-er, you can install a dishwasher without problems. The dishwasher comes with two hook-up challenges: the wiring and the water and drain lines. That's why it's a good idea to choose a location near your sink. It will save you time and money. Why oh why do you have to buy a dryer cord separately? It's one of the great mysteries of home improvement, but it's a fact of life. Next time you need to install that new dryer, you'll be prepared after this tutorial.

Turn off the power to the circuit you'll be working on by switching off the appropriate circuit breaker in your home's service panel (breaker box). Test all of the wires you'll be working on with a non-contact voltage tester. The test should confirm that no voltage is present in any of the wires.

In the second stage, the electrical equipment and the structures for the installation of wiring are transported to the construction site, installed in the planned locations, and assembled. In addition, cables and wires are laid and are connected to the installed electrical equipment. Electrical installation work is completed when the installed equipment is actuated and adjusted. The most complicated work in this respect is the adjustment of relay protection and automatic control systems for electric drives.

Copper has always been the first choice because it is such a good conductor and is very flexible. In the 1960 to 1970’s, aluminum wire became popular due to the rising cost of copper. Insulation was usually rubber although rubber tended to corrode due to exposure to moisture and air. PVC compounds are now used most commonly as wire insulation. Insulation is made in different colors to identify wiring circuits in a system.

In 1897, the National Fire Protection Association established the National Electric Code (NEC). The National Fire Protection Association was a group of Insurance companies that were concerned about the potential danger inherent in faulty electrical wiring. They had cause for concern. Early wire was bare or covered with cloth. There was little understanding of the need for insulation.

The first stage, which coincides in time with general construction work, includes the installation of fasteners or inserts in structural elements for the subsequent attachment of electrical equipment and structures for the installation of electric wiring. It also includes the installation of conduits for electric wiring in the foundations and floors of buildings or structures and the installation of wall sockets for outlets and switches. In the first stage, the preassembly of electrical equipment and wiring structures, the fabrication of conduit sections, and the board lacing of wires and cables for lighting and other circuits are carried out away from the construction site in specially equipped electrical-installation prefabrication shops.

Most states have a 100 amp minimum requirement. Homes running under that service could consider an upgrade to bring them to between 100 and 200 amps, which could run upwards of $2,000. Homeowners should evaluate their power demands first. “A homeowner can have an electrician test the system with an amp meter while all the big loads are on,” says Holt. “If the draw is over 75-80 percent of the service size, you might consider an upgrade. Otherwise you should be fine.”
