7. Which of the following is the amount of electricity imbalance required to trip a GFCI
and stop the flow of electricity to the circuit?
A. 12 amps
B. 10 amps
C. 0.005 of an amp
D. 0.10 of an amp
Note that it takes only 5 mA (0.005 A) of current leakage from the hot wire to the ground to cause a GFCI to trip. (Option C)
What is a GFCI?A GFCI is an electrical safety device that can protect people from getting shocked by electricity.
It can detect if electricity is leaking from a wire to the ground, which could be dangerous.
Even a tiny bit of electricity leaking, as little as 0.005 amps, can cause the GFCI to turn off the electricity to prevent anyone from getting hurt. So, it's important to use GFCI outlets to help keep people safe from electrical shocks.
