1.5" deep wall can I use BX??

Hi had to cut into a section of 2 x 6 wall to recess a 5' wide by 6.5' high with a header and then reduce that area under the header to a wall cavity thickness of 1.5 and 16" OC. It is an area under some steps that was designed for a washer and dryer but the builder said he could make it a 1/2 bath (toilet and sink). Well he screwed this up too. Wall to close so standard sink won't fit. I got hold of a old gas station sink and it is better but I still had to reduce the size of the 2 x 6 wall. So I want to add some electric to the wall so I have a medicine cabinet above the sink and need an outlet on this wall. I asked the electrician here and he said NO PROBLEM!!! I can use Romex I think I have to protect the wire from puncture and shorts.

So, who is right and will BX be adequate of do I have to try and run EMT or what??

suggestions, advice, recommendations

thanks

Just follow this graphic from Mike Holt and keep the cables 1 1/4" away from the framing. There are standoffs made to hold the cables in place.

Hi Jim Post, great drawing. This does help I hadn't looked at it that way but it makes sense. The use of furring strips on all those basements and the sheetrock placed so close to the wall. I will search out the standoffs. Now, what to do with the BX??

thanks

You can use the BX cable it the same rules as Jim Port posted the photo with standoff.

However there one issue with BX cable I am not sure which type of BX cable due there are few diffrent style of BX cable which it can be MC { metal clad } so the methold of use them will varies a bit as long the basement wall is very dry with no moisture show up { a quick vapour barrier test will show up on that one } then any type of cable or conduit will work.

Most of my furring strips sites which I have deal I hardly ever touch NM at all most case I run in conduit { useally EMT unless you have damp wall then I will switch over to PVC if that the case }

Merci.
Marc
