Kitchen Remodel Receptacle Spacing and Small-Appliance Circuits
During a kitchen remodel in Albuquerque, the existing 15 A circuit feeds six countertop receptacles and a refrigerator. The L-shaped counter has a 9 ft wall and a 6 ft wall, with a sink centered on the 9 ft run. There is a 6 ft by 3 ft island with a prep sink. Receptacles are currently spaced at 3 ft and 7 ft on the 9 ft wall, none on the 6 ft wall, and one on the island 8 in below the countertop. The homeowner wants to keep the 15 A circuit because 'the breaker has never tripped.' The walls are open, and the electrician is asked to make the kitchen compliant with the adopted NEC and pass rough-in inspection. The jurisdiction enforces GFCI and AFCI rules and tamper-resistant requirements for dwelling units. Assume the adopted edition still requires an island receptacle where the countertop area is at least 12 in by 24 in. The electrician plans to add two receptacles on the 6 ft wall and leave the rest.
1. Evaluate receptacle spacing on the 9 ft and 6 ft counter walls. How many receptacles are required, and does the proposed plan comply?

Convert to inches: 9 ft = 108 in and 6 ft = 72 in. Countertop receptacles must be placed so that no point along the wall line is more than 24 in from a receptacle; equivalently, the spacing between receptacles cannot exceed 48 in and each end cannot be more than 24 in from a receptacle. On the 108 in wall, the existing receptacles at 36 in and 84 in leave 36 in from the left end to the first receptacle, which exceeds 24 in. The 48 in gap between them is exactly at the limit, and the right end is 24 in, so the left end is the violation. Two receptacles cannot cover 108 in because the maximum span is 48 in between them plus 24 in at each end, or 96 in total. Three are needed, such as at 12 in, 36 in, and 84 in, or by relocating to 24 in, 72 in, and 96 in. On the 72 in wall, two receptacles are sufficient if placed so the ends and midpoint are each within 24 in, for example at 24 in and 72 in, or at 18 in and 54 in. The plan to add two on the 6 ft wall is correct, but leaving the 9 ft wall as-is is not.
2. Evaluate the island receptacle and the 15 A circuit. What must change before rough-in approval?

The island countertop is 72 in by 36 in, which exceeds the 12 in by 24 in threshold, so one island receptacle is required under the assumed edition. The existing receptacle 8 in below the countertop does not satisfy the countertop receptacle location rules; it must be above the countertop, not mounted below it on the side of the island. The 15 A circuit is also a problem: countertop receptacles must be supplied by at least two 20 A small-appliance branch circuits, and the 15 A circuit cannot serve those countertop receptacles. The refrigerator may be supplied by an individual branch circuit or by one of the small-appliance circuits, but it cannot justify keeping the countertop receptacles on a 15 A circuit. The electrician should install two 20 A small-appliance circuits, relocate or add the island receptacle above the countertop, and correct the 9 ft wall spacing before the rough-in inspection.
3. What protective-device requirements apply to these kitchen receptacles, and why are they not optional?
Read the worked answer
Kitchen countertop receptacles in a dwelling unit require GFCI protection because they serve areas where moisture and routine cleaning create shock risk; this applies to the 20 A small-appliance circuits and the island receptacle. The circuits also require AFCI protection under the dwelling-unit AFCI rules for 120 V, 15 A and 20 A branch circuits, so the breaker or outlet must provide that protection. Receptacles in dwelling units must be tamper-resistant, including the kitchen and island locations. These are not optional upgrades: if the inspector finds a 15 A countertop circuit, a missing GFCI, a missing AFCI, or non-tamper-resistant receptacles, the rough-in or final inspection can be failed and the circuit may have to be reworked. The electrician should verify the exact adopted edition, but the plan to leave the existing 15 A circuit and below-counter island receptacle cannot be approved.
