2 issues - need to read code

[syakoban]

I'm looking for the code on 2 residential issues:

1) Circuits for ceiling mounted lighting fixtures. I'm being told that it's code to have a switch at every room entrance for primary overhead lights in the room.

2) Troffer style recessed fluorescent lighting recessed between joists in a ceiling. In a residential application is there code that states a "firebox" must be constructed within the joist bay where each fixture is installed?

I looked in the article 400 - 410 section but could not find anything on these issues. Can someone direct me to the right sections that describe these topics?

Thanks.

1. See 210.70.

2. See 410.64(A).

Look at 210.70

The fire box question, I don't know

Thanks guys!

That's what I was looking for. I know that fluorescents work far below 194 deg. F so I was skeptical about the "firebox" issue... unless boxing them in would make them exceedingly hot...

The "firebox" issue may be confused with the "airtight" fixtures that are being required by the energy conservation/building codes.

the flourescent luminaire could be a listing that requires a firebox not sure haven't seen the directions.
