Hey guys, I am new here. I was wiring in a new dimmer switch that needs a ground and my house apparently has all the ground wires in the switch boxes capped together with one wire running out of the top of the cap. The individual wires are not long enough to run to the switches, but the one wire running out of the top of the cap is. I was wondering if it is okay to run that one wire to each switch for a ground? Where I am at the code is nfpa70, but I don't have access to look it up or know what I am looking for. I would appreciate any help. I don't want to start a fire or be out of code or anything.
