G0B05
Which of the following conditions will cause a ground fault circuit interrupter (GFCI) to disconnect AC power?
Pick an answer to check it.
Answer: B. Current flowing from one or more of the hot wires directly to ground
A GFCI trips when current flows from a hot wire directly to ground instead of returning through the neutral. Normal hot-to-neutral current is how equipment operates.
Tip: GFCI catches current leaking to ground.
