These labels are also standard and will tell you more information about the makeup of the wire. For instance, the code may tell you whether it's aluminum or copper or whether or not it is heat resistant. As you learn more about wiring, you'll realize just how often you need to know these things.

The place where a wire is joined to another wire or attaches to a device is the point where there is the most danger of a spark. It is important that connections are secure. Insulated plastic wire nuts are used to attach two wires. There are also special tools used by electricians to deal with the installation of wiring. An example is the combination wire cutter and stripper. The stripper is used to remove the insulation from the end of the wire so that the bare wire might be attached.

Note: The ends of the individual wires should be clean, straight, and undamaged. Their insulation should be stripped 1/2 to 3/4 inch from the ends. Trim any damaged wires and/or strip insulation as needed, using wire strippers.

Regular testing and evaluation of receptacles, switches, and breakers can prevent dangerous situations down the road. There are two electrical upgrades that should be installed to protect your home: ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs). GFCIs protect against electrical shock caused by ground faults or leaking electrical current. These devices monitor the current in a circuit and interrupt or stop the flow of power to that circuit if a spike or loss of power is detected. In new construction, GFCI receptacles are required by code in bathrooms, kitchens, and garages, on outdoor outlets, and in crawl spaces or unfinished basements.

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.

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets and light fittings in a structure. Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.

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.

"AFCI’s give great fire protection to homes with older wiring,” says Mike Holt, licensed electrician, electrical inspector, instructor, and founder of Mike Holt Enterprises, providers of educational resources to those in the electrical profession and related fields. Currently, the National Electric Code requires AFCI breakers for circuits providing power to bedrooms, living rooms, family rooms, and other common rooms in new construction. The cost for an AFCI breaker varies by manufacturer, but consumers can expect to pay around $30 to $35 apiece.
