I work on a Naval base and in one of there buildings they a 208V panel.Years ago someone installed an air handler less than 18" from the panel.They now want me to install another branch circuit from that panel.
Is it against the NEC code to work on that panel and install another circuit
 
Re: old illegal system

your new circuit is not a code violation and nothing in nec stops you from working on anything.However this panel is still a violation.If this requires inspection then i suspect you will be red taged for the work space even if existing.Just exactly where is this unit in relationship to the panel ?

Re: old illegal system

You are asking a question on a NEC forum so I assume you have a copy of the 2002 NEC
1. Years ago someone installed an air handler less than 18" from the panel.
Working space is in section 110.26. The panel requires 30" wide, the depth is 36" and the height is 6 ft 6 in. Image a refrigerator box in front of the pane. The 30" wide does not have to be centered on the panel.
2. Is it against the NEC code to work on that panel and install another circuit?
Maybe, but probably not Do you consider yourself qualified to work on the equipment?

The location of the air handler makes a difference. (is it above or to the side?)

Re: old illegal system

ok say 18 " form the panel plus the width of the panel which just might be 20 inches which is about what I would figure and you have 38"" so where are we in violation? and yes assuming the air handler is to the side and not within the 6'6"area it seems to e you are good to go.

Re: old illegal system

you didnt mention if the air handler was 18inch in front/to the side or what..... but, remember, the panel was there before the air handler. so,

Art. 110.26(A) Working Space. Working space for equipment operating at 600 volts, nominal, or less to ground and likely to require examination, adjustment, servicing, or maintenance while energized shall comply with the dimensions of 110.26(A)(1), (2), and (3) or as required or permitted elsewhere in this Code.

so as long as you do this while its not energized , you sorta ride the grey area.......bottom line, its on a Navy base and it aint goin to get fixed!! run your new circuit.....best to you
