Cat IV vent near electrical panel?

niklaw1 Member Posts: 9
Can an electrical panel be installed 12" under a bay vent for a Cat I appliance? I cant find anything in the IMC or IFGC nor Lochinvar's install manual about panels.

    Probably yes if you maintain proper clearances for the panel-sides, above and space in front of.
    Good question for an electrician, hopefully @Ironman will see the post and weigh in.

    I don't see an issue as long as the wiring is kept away from the vent pipe. I am assuming your talking about the vent pipe run over the top of the panel.

    As far as access to the front of the panel:

    30" minimum width or the width of the panel if it is more than 30"

    Nothing below the panel on the floor

    There is no specific height for mounting the panel but 6' to the top of the panel is normal.

    As far a clearance above the panel from the floor you need 6'6" headroom (I think I would have to look that one up)

    I believe In general work clearance space requirement around electrical panels is for electrician work space (easy of working on the electrical panel).

    I'ld make sure there's no seam over the panel that might drip.

    The area immediately above a panel (dimensions match the dimensions of the top of the panel) may not have any other trade or mechanicals running through it, up to a structural ceiling (e.g. drywall, not a lay-in grid).

    Section 110.26 of the NEC prohibits any kind of piping, ducting, etc, above a panel for up to 6' above the panel or to the ceiling.

    You can choose to do what you want, but you cannot choose the consequences.
