300.22

[Pro300]

Code section 300.22 is not clear on switches and receptacles in other space for enviormental air.
Is there anything in the code that clairfies this situtation? I can not find references that allow it and I can not find references that do not allow this.

I would say if you can satisfy 300.22(C)(2) but I would guess that you cannot with switches and receptacles. Does the plastic on the switch have adequate fire resisitance and low smoke producing characteristics? If you can show that then I would say go for it.:smile:

IMO if the switches or receptacles are in metal enclosures then it is acceptable.

Check out these nifty products, they are listed for environmental air space. Haven't had to use them, but I imagine you could put in a switch as well with the receptacle.
