Trip Switch

The trip switch is a kind of master circuit breaker that monitors the flow of current through all electrical wiring and disconnects the supply of electricity if it detects any abnormalities, from the tiniest imbalance (such as if a power board is overloaded) to large surges (such as during an electrical storm). If the amount of current flowing in is the same as the amount flowing out, the switches remain on. If there is an imbalance, the switch is “tripped” and the flow of current to the entire house is cut off.
