A review of Circuit Breakers and their Role in Electrical Wiring

By Mark J. Donovan

In this video, Mark Donovan of 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.

Warning: When working with electricity use extreme caution to avoid the risk of electrical shock. Make sure to first shut off power at the main circuit panel and then confirm all power to the electrical fixtures and boxes are off prior to beginning any work on them.
