I just had a new metal entry box installed on the exterior of my home. I am unable to open the metal door, even with a tool. Not sure what the problem is however if the door was installed and not plumb with the box frame, could this be the problem? My neighbor came down and he had difficulty opening it and said it should not be that hard to open.Thanks.enter image description here

  • I'm assuming you had an electrician install it?? Proper operation of the door should be a part of any such job. I suggest having the installer come back and correct the problem. – jwh20 Jun 13 at 20:33
  • He is a licensed electrician however I noted he was rather sloppy during installing of panel. After it was inspected by Code he came back to add a surge protector. When he installed it with the green light facing the ground, I asked if that was the way it was suppose to be and he said” it is ok like that”.When I could not see the green light I called Square D and they affirmed it should not be facing the ground? He is coming back to install another one I picked up with front facing light. His should have been side mounted. He has to use the same opening or there would be a hole in the box.

That is a "NEMA 3R" enclosure, meaning it is rated to be used outdoors. The door for those often have a "trick" to opening them because they are designed to keep rain out even when open, so there is a "drip lip" over the door. That sometimes requires that after you unlatch it, you must lift the door up from the bottom a little bit to get it off the catch, then let it drop down so that it will get clear of the lip and allow it to swing open.

If it's not that, then all he probably needs to do is shim the back of it. It appears as though he removed something else to put this in, and the wall behind it may be uneven. having to shim the back of the new panel is very common, the sheet metal is thin so any unevenness in the surface warps the box into a parallelogram. It can often just be done by putting washers on one or more of the mounting screws, BETWEEN the wall and the back of the panel.

    @J Raefield that makes sense! The surface behind is stucco and after he removed the old box there were rough edges. I had to ask him to knock them off. He was going to leave lumps of stucco. I bet the wall is uneven behind the box and it is not sitting flat on the wall, resulting in the box not being square. I will try your door suggestion and see if it works. The clip is so tight that I have to force it over with all my mite( I am no weakling either). I dread discussing this with him on Monday. The door catches on the surge protector when it is opened or closed also ☹️ – Kat Jun 14 at 1:38
  • Thank you everyone for your suggestions! The electrician returned and told me that he installs all the surge protectors with the light facing the ground and it is personal preference to be able to see it directly rather than standing on their head! 😲 His wife insisted that the Square D rep who told me it was installed incorrectly was only trying to up sell me. She got upset when I told her no, that they had not installed as manufacturer expected. He made an adjustment on the latch and now I can open the door! So happy to be done with them!! – Kat Jun 19 at 23:14
  • Actually, there is nothing in the installation instructions for that SPD that dictates a right or wrong way to install it. it only says that you should be able to see the LED. Given that the box is outdoors, I may have mounted it on the bottom like that too because it gives it some protection from physical damage and rain as opposed to being on the side. You can't mount it on the cover. – J. Raefield Jun 20 at 21:34
