    A:  Depends. Are we talking about just wires (not advisable) or Romex? Romex 2. Reg wires probably 6 but again not advisable. Nowhere near code.

        Q:will this fit a 1" hole in the junction box?

        Answer This Question

        A:  Knock outs (K.O.) are the following sizes: 1/2in = 0.840in, 3/4in = 1.109in, 1in = 1.375in. Electrical (like plumbing) uses the insides of conduit and fittings to run wire so the I.D. is the trade size.

          A:  No. I measured the diameter across the threads in the store yesterday and it's 1.25 inches.

              It is easy to install and works well with multiple non metallic cables together. It is tough steel so you can wrench on the tightening nut with pliers without worry.
