I have a light with a grounded plug that I want to use on a timer I have on hand. Problem is the timer only accepts two pronged cords. Could I use one of these cheater plugs and connect the ground tab via ring terminal to a grounded cord plugged in close by?
That prong literally does nothing power wise, it is there to hold the plug in place. Pull the 3rd prong out with a pair of pliers.
The grounding prong is only there for safety and to keep the plug in place
