I have a 3 gang switch box I need to add a romex 14-2 that I fished from the ceiling. The problem is, all of the wires run into this box are run into the top. The box has built in wire clamps at top and bottom. I can't figure out how i could fish the new wire down to the bottom of the box. I know one option is to cut the box out and put in a new remodel line box. The question is this, I'm guessing I can't just piggy-back one wire into the same clamp as another right?
Yes, you likely can, if it will fit.
Many plastic nail-on boxes are rated for two wires per entry.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.

beautiful. Thats a big help. I did not want to have cut this box out. The strange thing is, whoever was here first actually ran two of the wires from underneatht he box, up and over to the top to feed them through rather than just coming up from the bottom of the box. Grrr. Thanks.
