Electricity and Breaker Panels The process of forcing electrons to move through a material creates electricity. A standard generator performs this process. The best material for carrying electricity is a "conductor." Most metals are excellent conductors and the most common material used for electrical wiring is copper. In order to provide protection from direct contact with the conductor, an "insulator" is used as a cover around the conductor. Electrons will not move easily through insulators such as most plastics and rubber. Insulators and proper grounding help to prevent electrical shocks. Typically, electricity is provided to your building or facility by way of...
