I have a designer who is adding a third main service in an existing electrical room. The existing equipment is a 3,000amp POCO pull section with distribution bussing; a 1,400amp MSB1 distribution main (w/gfi protection); and an existing MSB2, with 1,600amp distribution. They wish to add MSB3, which is a new 800amp distribution section. All existing equipment is installed against the walls in the room, which has only one exit, but has all required clearances provided. The new MSB3 is shown as being installed in the middle of the open space in the room. The working clearances appear to be compliant, but does this now create an obstruction to egress from this room? If working on equipment that will now be behind MSB3 (in relation to the only exit), is the means of egress now obstructed?
The designer is submitting example plans showing that someone in the room can go around the equipment to get to the exit. However, I still feel that this creates an obstruction to egress in this room. I have attached one of their drawings where they are demonstrating what they consider to be unobstructed egress from this electrical room. The unlabeled sections are distribution to several tenants in this mall.
Any opinions would be welcome.
Thank you,
