Did you know?
WebA ground fault circuit interrupter (GFCI) is a type of circuit breaker that is designed to quickly shut-off electric power in the event of a ground-fault. A “ground fault” describes a situation in which there is a break (fault) in the grounding path used to control the flow of electricity to an electrical system or tool.
WebCode Change Summary: Revised code definition. In the 2024 NEC, the definition of a main bonding jumper (MBJ) was revised to clarify that the MBJ connects the grounded circuit conductor to the equipment grounding conductor, or the supply-side bonding jumper, or both, at the service. http://electriciancentral.com/nec-chapter-1-article-100-definitions/
In electrical engineering, ground or earth is a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical equipment are connected to ground, to protect users from electrical shock hazard.
