Question 1 of 10
What does GFCI stand for?
GFCI stands for Ground-Fault Circuit Interrupter, a safety device that quickly disconnects power when a ground fault is detected.
Question 2 of 10
What is the primary function of a GFCI outlet?
GFCI outlets are designed to protect people from electric shock by detecting and interrupting ground faults.
Question 3 of 10
Where are GFCI outlets typically required to be installed?
GFCI outlets are required in areas where the likelihood of ground faults is higher due to moisture.
Question 4 of 10
Which terminals on a GFCI outlet connect to the incoming power supply from the main panel?
The Line terminals receive the HOT and Neutral conductors directly from the circuit breaker or power source.
Question 5 of 10
What is the purpose of the Load terminals on a GFCI outlet?
Load terminals are used to provide GFCI protection to downstream devices.
Question 6 of 10
What is the consequence of reversing the Line and Load terminals on a GFCI outlet?
Reversing the terminals will either prevent the GFCI from functioning or leave GFCI outlet and connected downstream outlets unprotected.
Question 7 of 10
Which screw color is typically used to connect the hot (line) conductor to the GFCI outlet?
The hot (line) conductor connects to the brass-colored screw.
Question 8 of 10
What is the acceptable leakage current that a GFCI outlet detects before disconnecting power?
GFCI outlets detect and disconnect power when a leakage current of 4-6mA is detected.
Question 9 of 10
If you only use the Line terminals of a GFCI outlet, which devices are protected?
If only the Line terminals are used, only the GFCI outlet is protected.
Question 10 of 10
Which section of the NEC code addresses GFCI requirements?
NEC – 210.8 addresses GFCI requirements for various locations.
