Hi all,
Though I've been reading everything for a while this is my first post. Let me start by saying that this an excellent forum, full of very useful information.

While I am that dreaded DYI'er, I'm also very conservative, try to learn as much as I can before beginning a job, and always have my work checked over by a professional.

That said, the answers to some of my questions have been difficult to find.

For example, what is the temperature rating of Romex? Is it suitable for use with halogen fixtures (box attached to directly to can) that require wiring rated to 90 deg. C? If so, can nonmetallic clamps be used on the box housing?

Another minor concern I've had is with the use of 20+ cubic inch single-gang boxes in 2X4 partition walls. The deep box brings the wires entering the box very close to the finish surface on the other side of the wall. Is this of any concern?

Your help is greatly appreciated.
