📚 How GFCI Protection Works
GFCI breakers trip when they detect as little as 4-6mA of current leakage to ground. The trip time depends on the current level - higher leakage trips faster.
The resistance of the wire creates a voltage drop that affects how quickly the GFCI can detect a fault condition.
NEC Requirement: GFCI protection is required for bathroom, kitchen, outdoor, and other wet location outlets within specific distances from water sources.
