Q: What is the purpose of a GFCI circuit breaker in a GracePort panel?

A: A circuit breaker is designed to protect electrical circuits from damage caused by overcurrent, which can result from an overload or a short circuit. It monitors the current flowing through the circuit, and when that current exceeds the breaker's rated amperage—for example, 15 amps on a 15A breaker—it trips and opens the circuit, stopping the flow of electricity.

Overloads occur when more current is drawn than the circuit is designed to handle, potentially causing overheating. Short circuits occur when current bypasses the intended load path, often resulting in very high current levels. Circuit breakers prevent these conditions from damaging wiring, connected equipment, or causing fire hazards.

By automatically interrupting dangerous current levels, the circuit breaker ensures that the wiring and connected devices stay within safe operating limits.
