In general an island countertop only requires one receptacle if not broken into separate spaces by a sink or other appliance, etc. If there is a wall then the 12"/24" rule would apply but then that wouldn't really be an island. Now if someone wants to call a backsplash a wall then we'll have a different argument.
210.52(B)(2) Island Countertop Spaces. At least one receptacle shall be installed at each island countertop space with a long dimension of 600 mm (24 in.) or greater and a short dimension of 300 mm (12 in.) or greater.
(4) Separate Spaces. Countertop spaces separated by rangetops, refrigerators, or sinks shall be considered as separate countertop spaces in applying the requirements of 210.52(C)(1). If a range, counter-mounted cooking unit, or sink is installed in an island or peninsular countertop and the depth of the countertop behind the range, counter-mounted cooking unit, or sink is less than 300 mm (12 in.), the range, counter-mounted cooking unit, or sink shall be considered to divide the countertop space into two separate countertop spaces. Each separate countertop space shall comply with the applicable requirements in 210.52(C).
does that just mean only 1 outlet is required within 2' of the sink or cooking unit no matter how long the island is?
Dennis, Technically I would say the penisula between wall counter & sink is greater than 24" x 12" & would require another receptacle( pop up) - In a situation like this a sensible call may be "as drawn" & move on as it does no pose life safety hazard & difficult to comply with. Its not a perfect world out there
Dennis - I would interprete your drawing as a 2' deep wall countertop with a 4' pennisula .
