My home needs a new electrical box installed. It is a Federal Pacific Stab Lok box. I understand these boxes have been discontued and have understand why. I am in the process of getting quotes now, but tonight I had my dishwasher serviced. I had the power off to the dishwasher and he was still getting shocked. He told me i needed to check the electical ground to my house. Were would that be and what would that look like. None of the electricians said anything about the house ground.
