What You Need to Know About Electrical Wires

The electrical systems in your home, vehicle and office provide needed energy for all of your appliances and may largely define the efficiency of your work or living space. Electrical wiring diagrams, wire replacement and other complex topics are often best left for a trained electrician, but a basic understanding of wiring processes and safety procedures can save you from unnecessary risks and potential damage.

What Is Wiring
Wiring connects all lighting, electrical equipment and appliances in your home. These wires are typically made of a highly conductive metal and coated with a plastic or rubberized insulating outer material. You should never attempt to strip the insulation from wires without knowledge of whether or not power still flows to the wires, and many people turn to electrical contractor firms instead of attempting home repair when it comes to wiring and hookups.

Avoid Uncertainty
Never attempt to check for electricity in downed wires or those in which you lack absolute certainty about their current power status. Downed power lines cause many fatalities each year, and only skilled electricians should tackle this problem. This includes wires unexpectedly pulled from ceilings or walls in your home due to accidents.

Turn Off the Power
When working with home or office wiring on your own, make sure that you have turned off power to the entire circuit at the main circuit breaker. In most cases, turning off the main breaker provides the safest method of preventing electrical hazards when you have to replace a wall outlet or for similar basic home repair work. Never work near plumbing, metal surfaces or liquids when attempting basic wiring repairs, and call in an electrician if you must work near gas pipes or other flammable materials.
