Subject: Plastic Switch/Outlet Gang Box Question
Date: Thu, 30 Dec 2004 16:02:12 -0500

Hello:

Will be adding a gang box for a new outlet, and also one for a wall switch
in a home residence.

Guess I'm really old fashioned, but all the ones I've installed were always 
metal.
The green ground wire was always grounded to the metal box, of course.

I see now that they sell plastic ones, as well as what I like to call the 
conventional
metal kinds.

My questions are:

Are the plastic "legal" per building codes these days ?  Allover ?

Or, does it depend on the local state building code (I live in Mass.) ?

Which are presently more popular ?

Thanks,
Bob
