Marty, what is this called? I am now in the process of helping a friend with his ground planes on his large layout and I am not sure about the ground part of his outlet.
Outlet tester in the generic sense. Available at any Home Depot or such.
An outlet tester like this is used on a three prong outlet. Purpose (Correct) noted at the bottom of the tester is to assure the outlet is wired properly, two yellow lights, middle and right, will light. The (5) incorrect wiring problems, are noted on the tester. Most common, since a lot of older home wiring, had no ground wires, would be (top) open ground. Open ground a problem with TMCC signal. Often if a two prong outlet broke, or was no longer use-able, it was replaced with a three prong outlet, round third prong bottom not attached to any wiring. larger left slot is attached to the white wire (neutral), smaller right slot is attached to the Black wire (power).
