Electrical siding pass through removal

electricalpool

I have a outdoor switch that controls my spa pump. As you can see in the photo, one of the armored pump electric cables is not threaded to the box. It was like this when I bought the house. The box is too close to the wall to turn the armored cable nut, so I need to pull the box out from the wall a bit.

The next picture shows the back (I have already removed the ground clamp and strain relief). As far as I can tell, I need to put a pipe wrench on that metal conduit and turn it counterclockwise so I can get at the ring clamp holding the box to the wall. I gave it the full muscle try and could not get that conduit to turn. Am I doing the right thing? Do I just need more force on the wrench? Is there a recommended fluid like PB Blaster I can use in there around the wires? Or does this come apart in some other way? It cannot be turning the box on the outside, because the armored cable prevents that.

Best Answer

  1. Turn off the power to this circuit (hopefully you already thought of that.)
  2. Take off the cover of the box on the outside.
  3. Take another picture, but it would be quite normal to find screws holding the box to the building as well as the conduit. Loosen or remove those screws, that may give you enough motion to do what you need to do.
  4. If you resort to lubricants/penetrants, remove the wires first. Then use the petroleum products, then clean everything up before reinstalling the wires.
