One means by which each conductor's use is identified and made distinguishable from the other circuit conductors is the us e of color coding. Acceptable color coding includes the method required by the National Electrical Code, Section 210-5. An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal. When a pair of contacts touch, they can pass an electrical current with a certain contact resistance, dependent on surface structure, surface chemistry and contact time; when the pair is separated by an the road movie 2018
