Thread: box accesability

  1. #1

    box accesability

    Looking for opinions on an install. Hard lid ceiling in a bathroom with two 2x4 fluorescent lights. CMU walls that extend all the way to the roof deck, basically leaving no access above the ceiling from inside or outside the room. Okay to set a box above the fixtures? I guess I am basically asking if a box is considered accessible if a fixture has to be totally removed from the ceiling to access it. Also, would it sway your opinion if the box feeds the lights? I feel the box would not be considered accessible, whether it is feeding the light or if it was just a pull box for a totally different circuit. Anyone else?

    If i am understanding your question correctly then here is my comment:

    That is how most of the wiring is done. Isn't it? you pull the wire, install the box and the fixture goes over the box. Perfectly fine installation.

    I'm sorry, bad description. Standard 4 square mounted to some structural steel with a whip to the light.

    No. Not accessible.

    Boxes above the ceiling and adjacent to recessed florescent fixtures are fine IMO. They have been installed that way for as long as flourescent fixtures have been made.

    The words "2x4 fluorescent lights" and "4 square mounted to some structural steel with a whip to the light" lead me to believe there is some distance between the box and the light.

    Just to play Devil's Advocate; The box is accessible once you remove the 2 X 4 luminare.

    Can you pipe directly into the fixture? Or does the box contain other circuits thus making the light a raceway?

    Sure, if there were an acess panel behind the light.

    From the OP I assumed that removeing the luminare gives you access to the space above
