I was wondering what type of wall box most of the people on this board like to use. I still would rather use steel.

I use plastic up to a 3 gang, 4 gang and over I go to metal. For basic residiential it is easier to use a plastic nail on as you don't have to bond it and it attaches to a stud a little quicker.

In NJ here for the res. type jobs. I see mostly plastic. For the commercial/ind. jobs, metal. I my self would use plastic, but I always used metal for light fixtures.

bfdpoc221...i use both types. but it depends on the framing.(wood or metal studs)new work res./and all metal in comm. there is an advance in using plastic. (1) the cost per box,(2) no need to ground the box.

Here in New York City it seems you're required to use metal boxes by default, since use of armored cable is apparently a code requirement.

Although I've seen the blue plastic boxes for sale at the Home Depot...what they're used in I don't know. Everything I've seen/dealt with has always been metal (which I prefer since they're much sturdier - plastic always can crack or the screwhole strip out if you over-tighten).

You cannot use armored cable with plastic boxes, only NM, right?

With the adoption of the NEC 1996 and the NYC ammendments as of January 2003, I do not see any general restrictions to using NM in non-commercial dwellings in NYC.

Plastic for resi, when we do it.
Metal on commercial, with MC cable.
IMHO, NMC does not belong in comm buildings.

bfdpoc221, We use metal 4" sq deeps with plaster rings and mounted with Caddy H3s for almost everything.

I am with ya Hotline1 We build a lot of 80,000 to 100,000 sq ft supermarkets and its 90% NMC. I hate to do it. When the local AHJ prohibits it we get about a $50K change order for MC

Iwire:
Curious; in the smkts, where do you run NMC?
They build with plenum ceilings???
What about occupancy??

You said..."a 50K change order when the AHJ prohibits it"; does the AHJ catch it at Plan Review, or after you have it installed??

BTW, what area are you from/in??
