Wiring an outlet using both ground screws instead of pig-tailing together.


I'm installing an outlet in a box where the ground wires are to short to pig-tail together (one ground wire in and one out). The the junction box has two ground screws. There is just enough room to get each ground wire under the separte ground screws (not enough length to get under same screw). Can I simply double up a ground screw for the ground wire running to the outlet?

The net result would be the incoming ground wire and the outlet ground wire would be on the same ground screw and the out going ground wire would have it's own screw.

Would this work?

Thanks for you help.

Only one wire should be under the screw head.

With some effort and needle nose pliers you can install a connector like the Ideal push-in's to splice the grounds.

Are you in Canada? The iberville metal boxes have two ground screws in the back like this ... Jims idea is a good way to go. The push ins work very well in your situation

Yes the box looks very similar. I have one wire coming from the top and one from the bottom.

Thanks for the advice. I'll have to look into these "push-ins". But just out of curosity would the original layout I described actually function?

If this is what you have then you are allowed to put one ground wire on each side of the screw head so that when you tighten the screw it pulls the ground wire in the direction your tightening. Like below ...you do not have to wrap the ground wire around the screw head. the raised ridges lock the wire under the screw head.....you must have those ridges in order to do this .. otherwise do as Jim described.
