10 Ground Wire In 4 Gang Box Crimp Question

846 Views 22 Replies 13 Participants Last post by  seharper
Good morning all,

I have a 4 gang box plastic and a need to connect 10, 14 awg ground wires. Red wire nuts are max 6, 14 awg wires and if I understand correctly for CA code each device has to have its own ground so I cant daisy chain ground from switch 1 to switch 4 then to main ground branch?

Whats ideal way to connect the grounds together? Can / Should I use a greenie and terminate all 6 romex wires together with 1 longer wire to then wire nut / join 4 pigtails from the switches?

Devices / wires:
1) power in 14/2
2) outside lights 14/2
3) front porch 14/2
4) entry light 14/2
5) 3 way 14/3 out to 2nd switch
6) power out 14/2

Forgive the sloppy art, trying to plan the termination for rough-in inspection before I start.

Is the box metal? If so, you don't need to wire grounds to the switches. They'll pick ground up automagically by way of the mounting screws.

Most 4-gang steel boxes have something like 8 ground screws on the metal box, so each ground wire from a cable gets its own screw.

Is the box not metal? Well, now you know that for next time.

If you can get a UL Listed version of one of those, that'd be great. I know they make Push connectors as many as 8 spaces.

Wait. Did you say GROUNDS?

You know, you could just buy an accessory ground bar intended for a service panel. They're like $6. Some of them are even listed for 2 grounds per hole.
