Q. What is the Code rule requiring the installation of a receptacle outlet for a peninsula or island countertop space?

A. At least one receptacle outlet must be installed at each island countertop space with a long dimension of 2 ft or more and a short dimension of 1 ft or more [210.52(C)(2)]. At least one receptacle outlet must be installed at each peninsular countertop with a long dimension of 2 ft or more (and a short dimension of 1 ft or more), measured from the connecting edge [210.52(C)(3)].

The Code doesn't require more than one receptacle outlet in an island or peninsular countertop space, regardless of the length of the countertop, unless the countertop is broken as described in 210.52(C)(4). When breaks occur in countertop spaces for rangetops, refrigerators, or sinks, each countertop space is considered as a separate countertop for determining receptacle placement [210.54(C)(4)].

If a range, counter-mounted cooking unit, or sink is installed in an island or peninsular countertop — and the depth of the counter behind the range, counter-mounted cooking unit, or sink is less than 12 in. — the countertop space is considered to be two separate countertop spaces, as shown in the Figure.

GFCI protection is required for all 15A and 20A, 125V receptacles that supply kitchen countertop surfaces [210.8(A)(6)].
