Question on Grounding 3-Gang Metal Box
- New House (Build 2011)
- Located in Ontario/Canada
- Basement Renovating Project
I have an existing 2 Gang Metal Box that house two light switches. I have replaced that with a 3 Gang Metal Box to add an additional light switch.
The builder had previously connected each bare cable to its own screw and did not bond all the bare cables together using a wire nut. The electrical code states you can connect one bare cable to a screw and bond the remainder bare cables to it using a wire nut.
I can't seam to find any information on whether or not it is acceptable to do what the builder had originally done. Basically attach each bare cable to its own screw and not bond them together with a wire nut. I'm asking because this would save me some room in the box.
Any help is appreciated. Thanks
I'd pigtail them together and connect 1 to the box if it were me.
Thanks for the reply,
That's the way I have it setup now. However, the 7 bare cables and two red wire nuts are taking up quite a bit of room. That's why I was considering the option of terminating them to a screw instead.
Put one under every screw and cut them flush, if you need to ground a switch leave one long enough after going under the screw to reach the switch.
Most ground screws can accept two wires as well, there is usually two raised pieces next to the screw, put one wire on each side and tighten it down.
