Electrical energy enters your home at the circuit breaker or fuse box and branches out to appliances, wall sockets, and lights.
Circuit breaker – small piece of metal that bends when it gets hot, opening the circuit and stopping current flow
Electric fuse – small piece of metal that melts if current becomes too high, opening the circuit
