ICC Residential Electrical Inspectors Practice Exam

Which type of wiring is required for kitchen countertop receptacles?

Standard wiring Ground-fault circuit interrupter (GFCI) wiring Twisted-pair wiring Coaxial wiring

Correct Answer:

Ground-fault circuit interrupter (GFCI) wiring

Explanation:

Kitchen countertop receptacles are required to be connected to ground-fault circuit interrupter (GFCI) wiring. This requirement is in place to enhance safety, as kitchens are areas where water is commonly present, increasing the risk of electrical shock. GFCI devices are designed to quickly shut off power if they detect ground faults, which can occur when electrical current escapes from the intended path. In residential codes, especially as outlined in the National Electrical Code (NEC), GFCI protection is mandated in locations where moisture can pose a hazard, including kitchen countertops. This rule helps to safeguard users from potential accidents involving electric shock, making GFCI wiring the standard for this application in modern electrical installations.
