wall box,connections for armored cabling

tmorriss · 03-21-2011, 09:54 AM

Purchased a new Electrolux double wall oven -240v-for my kitchen remodeling.
I"ve run a new 6-3 line to the location where the new ovens will be.
I'm not sure what would be the 'correct' way to make the connections
as far as the box and covering it goes.

I have an 'old construction' plastic double gang /deep box I was planning on using, but they are big wires and I"m not sure they are going to fit in their easily.

Is there a 'special' wall box to use for this type of application?

Secondly, the new ovens have an armored cable.

Is there a proper way to makes this connection to the box.

My old oven (put in by the original contractor), was just left open and the connections made and the wires stuffed inside it. THen left that way(for 30 years

I'm thinking there must be some type of a 'blank' with a knockout in the middle that I need for this yet to be determined 'large' wall box I should have?

Or, is how it was done the first time proper? Just hook em up bl-bl, rd-rd-wh-wh and grd-grd and stuff em all inside this box and just leave it (common sense tells me NO )

Thx in advance

Many times you will not need to flush mount the box in the wall. I typically use a deep 4x4 or 4 11/16 box screwed to the stud on the surface. I use the knockout on the side of the box and then a blank cover. Check the installation manual for the proper box location.

You will need to use a metal box with the flex cable and a proper connector.

I would use a metal box instead of plastic, get the deepest 4" square box you can find and a blank cover. Use a NM (Romex) cable connector to secure the new supply cable. The metal whip (conduit) from the oven should have a similar connector. W - W , Bk - Bk, R -R and grd - grd is correct. Also ground the metal box with a short pigtail.

HI,
I won't be able to mount the box on the wall face surface. It's going into a cabinet which is flush against the wall and the cabinet interior looks to not have enough room for the box behind the ovens. I guess I"ll be knocking 'another' hole in the wall

Thx

All the ones I have wired, the box mounts under the oven, then the oven in installed.

I did wire one through the wall into the garage where the panel was located.
Is this in a raised cabinet, or sit flush to the floor?
