When verifying GFCI protection, what should be checked about downstream outlets?

• A. That GFCI only protects the outlet it is installed on and no downstream devices.
• B. That no outlets beyond GFCI require protection.
• C. That the GFCI is installed in the main panel.
• D. That downstream outlets are protected as required.

Answer: (D)

When verifying GFCI protection, the key is to ensure that any outlets fed from the GFCI are protected as required. A GFCI protects all receptacles connected to its load terminals, so you must confirm those downstream outlets are wired to the load side and will trip if a ground fault occurs. Test by using the GFCI’s own test button and verify that downstream outlets lose power, then reset to restore. This confirms ongoing protection for all outlets that are intended to be protected. If outlets beyond the GFCI aren’t protected when they should be, wiring them to the load side or correcting the installation is needed.
