Am installing copper countertop on island that is 48" x 96" with electrical outlets on either side.
Do I have to ground it some way? How to do?
The outlets will have their own ground, and anything plugged into them will be grounded (if it has a 3 prong plug).
The outlets will also have a GFCI that will detect any current leakage.
The general rule is that metal 'likely to become electrified' needs grounding.
A counter is NOT in this class.
Thanks so much.
