Working Space

[Rough Draft]

Hey all, I'm looking into moving some panels around in a future electric room to make space for some overhead ductwork.
My question is, would the placement of this ATS violate the working space in front of T-1? T-1 is 480:208/120V

Is the distance shown to the side of T-1 (non removable) ??

Correct, non removable. The removable cover would be towards the ATS.
Trying to gain space between AB and EM by turning T-1 to the position shown.
T-1 originally opened towards the MDP

IMO, it would be Code compliant. The side compartment of T-1 would simply be a grounded surface.

Do you think there is any issue with the front edge of the ATS being at 3' in front of the transformer cover?

 

[augie47]

Opps.. I missed that measurement.. it might well be an AHJ call but more inspectors that I've worked with don't consider a transformer to fall under the "subject to be orked on while energized" clause.

Thanks

It would appear the transformer doesn't maintain the required working space, as you suspected.

Is the ceiling high enough that you could suspend the transformer above the height of the ATS?

That could work. There's no ceiling in there, but I can't find the height of trusses/purlins above. The ceiling in the room next to it is 9'
