Code Change Summary: Additional code language clarifies how to measure a kitchen peninsula when determining receptacle placement.

For many code cycles, a kitchen peninsula has been measured from the “connecting edge” which is where the peninsula countertop makes connection to the kitchen countertop. In the 2017 NEC a peninsula is now measured from the connected perpendicular wall.

This means that receptacle number 1 in the image, installed to serve the countertop wall space can also serve as the receptacle required for the peninsula because receptacle 1 is located within the envelope of the peninsula. According to the revised 2017 code language, receptacle 2 in the image is not necessary.

In the 2014 NEC, both receptacle 1 and 2 in the image were code required since the peninsula was measured from the connecting countertop edge and did not go clear to the wall. Now that the 2017 NEC requires the peninsula to be measured from the adjacent wall, the receptacle required for the peninsula can be satisfied by receptacle 1 in the image which also serves the adjacent counter.
