Hello all, I have an electrical room (NYC building) with one double door means of egress, I have CT cabinet facing to the side of a distribution board (2000A rated), do I need to follow "Extra working Space" NEC 2008- 110.26 (C)(2)(b) section with double the clearance for a room with one egress? Does the clearance in front of the CT cabinet also need to be doubled for that matter?

Appreciate any help to sort this confusion out.
 
If the distribution panel and exit doors are on opposite walls, then double working space will satisfy the rule. If they are on adjacent walls, you might have a no-win situation.

I don't believe a CT cabinet requires working clearance at all, as I don't see it needing maintenance while energized. Others may disagree with this.
 
Coned has their own rules. Send a question on project center and update us.
Last time I asked here for clearance of ct cabinet (low amps) was it does not require 3 ft clearance by nec but coned requires 3 ft for their workers
