Install new ground wire for non-grounded receptacles
I am planning on running grounds to my upstairs plugs that are currently K&T with the two hole groundless plugs.
Question is, can I run several of the grounds into a centrally located j-box and then just run one larger ground back to the panel?
I can't imagine running a separate wire for every receptacle back to the panel. My panel doesn't have enough ground lugs to accommodate all of them. Actually, I'm not sure I'm going to do all of them. Maybe just the ones where I have ground critical equipment installed.
Also, should the wire be the bare type wire, or the green insulated wire?
Thanks to any and all... you guys are very helpful.
