Thread: Wires are too short to connect inside a junction box.

  1. #1

    Question Wires are too short to connect inside a junction box.

    I installed a light fixture on the side of my garage, and I ran a line to get power from an existing light fixture on the front of the garage. I want both lights to be on the same line so they can share the existing switch that controls the front light. I could not tap into the electrical box at the front light fixture because the front of the garage is bricked and I could not feed the new cable from inside the garage through the wall (I suspect the cable does not go straight through the wall, but makes a turn before going through the brick). So, I cut into the cable from inside the garage and made my connections inside a junction box.

    My problem is that when I cut the existing cable the wires were too short to connect inside the junction box, so I pigtailed a few scrap pieces of wire to make them long enough to connect. I connected them in a 4" x 4" junction box and placed a cover plate on it. The junction box is accessible.

    My question is, is this the correct way to make the connection? Or, I read that I could install 2 junction boxes about a foot apart and install a cable this is long enough in between both boxes? Or do you have any other suggestions?

    Thank you,

    Vinny

    You must keep the wirenuts in a junction box they cannot be left in the open air void. Funny I see this all the time but doesnt make it acceptable. Your only choice is 2 junction boxes or rewire the circuit.

    Thank for responding to my question. I did make all the connections in 4" x 4" junction box and covered it. I should have made that clear when I wrote that I pigtailed a few scrap pieces of wire to make them long enough to connect. I will edit my original question.

    If all you did was make the individual wires longer with short pigtails within the JB then you are fine.

    That's exactly what I did.

    Thanks

    You may get away with it once but having the cable conductor ends too short after they enter the box can cause you to fail the rough inspection.

    But I find it hard to understand that, while (in my town) the rules say wire ends at least 6 inches long for rough inspection, it is common to trim the wires back, perhaps to 3 to 4 inches, when wire nutting on pigtails for, say, outlets.
