Circuit Breaker
Definition and meaning of Circuit Breaker in real estate.
A circuit breaker is an automatic safety switch designed to interrupt the flow of electricity in a circuit when the current exceeds safe levels due to an overload or a short circuit. Unlike a fuse, a circuit breaker can be reset manually once the electrical issue has been resolved.
In more detail
Circuit breakers are the primary line of defense against electrical fires in modern residential properties. They are housed inside the main service panel, with each breaker dedicated to a specific circuit in the home. When a breaker trips, it snaps from the on position to a middle or off position, cutting power to that specific area.
Flipped breakers are common when operating high-wattage appliances simultaneously. During a home inspection, the inspector will check the panel to ensure the breakers are properly sized, not double-tapped, and functioning safely.
