I have an architectural drawing showing a janitors closet with electrical panels and a slop sink. You must walk by the panels to access the slop sink. I am asking the design team to make two separate rooms. I am using code art 110.11,110.21(B)110.26(a);(1);(C) and 110.27 (B);(C) as my basis for judgment. The electrical engineer disagrees saying the room is not an electrical room, your thoughts would be greatly appreciated.
Hey Scott thanks for your question. Unless the equipment has exposed live parts dedicated or separate rooms for electrical equipment, of the type you are describing, are not generally required by the NEC - even though many of us would prefer it that way. Working spaces must be provided as stated in 110.26 but having an electrical room, or any kind of room is not included in those rules. Live parts must be guarded as stated in 110.27 but the equipment enclosures usually do that.
