Hi all,

i do not have my code book at the jobsite today and a question has come up.
the clearance distance around a box rated 480 or less is 3 ft out from the box and a width of 3 ft for small boxes or if its a wide box, the doors must open a full
90 degrees as i understand it. the engineering team wants us to put another box within 18 inches of a breaker box. to me, you cannot work on both boxes at the same time and maintain the required boundary. they must be 3 ft apart.
am i correct in my thinking? if not please clarify the rules for me.
thanks in advance,
philip
