Ground fault circuit breaker
What is an ground fault circuit breaker?
A ground fault circuit breaker, also known as a fault current protection switch or residual current operated device, is an electrical component that monitors the strength of electrical currents. When fault currents are detected flowing from or towards a device, the ground fault circuit breaker cuts the current to whatever is consuming it within milliseconds. In this way, people and animals are protected from dangerous and lethal electrical accidents. Fault currents may be caused by defective cable insulators or moisture damage. Install a ground fault circuit breaker before your electric fence’s mains energiser to prevent electrical accidents.
