I just installed a spare AC disconnect and noticed how the romex connector is in the way when you secure it to the structure. I left it a little crooked and sealed up around it with seal.

What do you guys do about the romex connectors?

if the romex is legal in the manner you are using it, a bigger hole in the wall/siding will allow the connector to recess into the wall. I only apply silicone on the top and sides of the disco so any water that does get behind the thing can drain away rather than accumulating and eventually running into the wall.

just in case I am misunderstanding this; you are talking about running the romex out the back of the disco, yes?

Yes, out the back. I'm fixing some other sparkies work. He or she pulled nm-b through liquid tight conduit to the AC's, secured the disco to the wall with one screw, and ran the nm-b through the bottom of the disco (means the romex is exposed to outside conditions.

I drilled a 1 inch hole and the connector almost fit into the hole.

Edit-when you mean "legal in the way your using it" do you mean I cannot use nm-b going into the disco because it uses thhn conductors?

you cannot use thhn or nm in a wet or damp location application. If it is exposed, it is most assuredly a damp or wet location. Even in conduit, it generally is not legit if outside.

Use a black-button type, sometimes referred to hit-lock:



They pop in your knockout, and then you can mount your disconnect box on the wall. The nubs on the back of the disco box are usually sufficient to provide adequate space for the flat part of the connector behind the box.

Sounds like a good idea, but, nap said that I cannot use nm-b outside, I know that, but can't I run it from inside the house to the disco?

As long as you enter the disco thru the wall and directly into the back of the enclosure, the NM isn't considered to be "outside" per se, since it isn't really exposed to the elements.:whistling2:

maybe I misread but I thought you said it came in to the bottom of the disco. That would mean it was exposed.

If it comes in to the back, then you can generally get away with NM.
It is going into the bottom for two other discos, so I'm going to fix that problem by entering through the back. I also need to get thwn and put it through the liquid tight. The "electricians" used romex through the liquid tight and were the ones who put it through the bottom of the disco.
