In this video, Mark Donovan of
HomeAdditionPlus.com discusses circuit breakers in home electrical wiring.
Circuit breakers play a significant role in protecting your home from fire.
When too much current flows through a wire the wire gets hot. If allowed to
continue the wire could get so hot that a fire is started. A circuit breaker
senses the increase in current and stops the flow of power to the circuit,
thus preventing the threat of fire.
