So far this is real good but leads to a second question if you would be so kind the day before Christmas.
I have receptacles that are looking between two apartments on the two walls that separate the two units. As far as the building code what if any thing must be done to prevent the spread of fire or to maintain the fire rating of the two walls.
Do I install fire pads to just one box or does both boxes require fire rating?
Thank you and Merry Christmas

There are a lot of factors that go in to the correct answer on this one. Best course of action - consult the RDP and AHJ. Follow their advice/direction.jwelectric said:

Darren has a really good way to start.....first thing to determine when you have a "rated wall" is wether you have a fire wall, fire barrier, or fire partition and then the rating and then the penetration protetion required........and NEVER put anything in a wall that is part of a rated stair enclosure unless it serves the stair....
