It's really difficult to shove all the #12 solid wires back into a handybox when wiring a new 20A duplex outlet outlet and another cable exits the box to feed the next outlet. And the main problem seems to be the #12 wire to ground the box. I'm tempted to use #14 bare wire, since the box *should* be grounded by the yoke of the installed outlet. But even that would be a stiff solid wire going the wrong general direction to bend easily.
What about using #12 green-insulated stranded wire? Can it be twisted into the red wirenut with the other three #12 bare solid wires? Do I need to crimp on a terminal lug, or just twist the strands into a little loop and hook them under the green ground screw?
Even better would be to use a stranded wire pigtail on the outlet and a stranded wire for the box, so I'd have two solid grounding wire and two stranded wires.
I have one box to wire with *two* cables coming out of it feeded other boxes. That one will be really fun to get all the wires in. :-( I'll use an extra deep gangable box for that one and wire it up with the side removed until I shove wires in from the side.
I'm too stubborn to use plastic boxes for exposed work, but I am using plastic ceiling boxes just so I don't have to ground them.
Thanks, regards, Bob
