NEC 110.26 Transformer Pad

[xguard]

I'm looking at installing an ATS, one possible location is shown in the attached photo and marked by the red rectangle. The transformer pad is 2.5 inches high and will be within the working space.

I'd say typically I would choose another spot and not give this a second look but maybe I'm being overly strict and as such would like additional opinions. Also, if 2.5 inches is too high of a difference (or not enough if you are on the other side) where would you draw the line?

if its just the pad that will be in the working space why not over poor the pad and take it to the brick wall so you be standing on it while working on the panel

I try to shoot for a flat platform for the working space, so as mentioned by David, just extend the pad so it fully encompasses the ATS working space

What am I not understanding? If you have a pad, then you would have something sitting on it, yes?
That something, transformer or generator, would also be in the working space, not just the pad.

Isn't the pad usually larger than the equipment setting on it? You may be correct don't know from what the OP posted

I'm not following. Are you able to see the photo? The new ATS would be mounted on the screen wall.

How are you going to mount the ATS? That wall doesn't look all that supportive!

From the size of the outline, it looks pretty healthy.
Strut or fabricated steel supported from the new, flush, extended, concrete pad.
If fabricated steel, may not even need grouted bolts into the bricks.

Just a thought.

Its obviously an AHJ call. I think most inspectors would accept it. Outdoors you might have a 2.5" dirt in any event.
Just tell the inspector the electrician that's working on it has 1 leg 2.5" shorter than the other

Since that looks like a POCO xformer, are they going to be OK with this possibly encroaching on their work space?

I'm meeting with them on site tomorrow to ask about that and a few other things.

I went back and looked, but your description lacked a little for me. I didn't realize the pad was there already. That transformer looked like a dumpster. I was thinking you were setting something in front of the outline you drew on the wall.

Worse case, you have to fill in the 2.5" difference with concrete or something. I would run it by the inspector.

If issue does presents itself w/ your Code Inforcement, I'd give consideration in possibly "saw cutting & scoring" just enuff excess from the backside of transformer's house keeping pad, removing just enuff pad @ angle for new ATS. The incountering of reinforcement involved in concrete removal, it's possibly not too excessive. Remove the excess of scored concrete pad w/ roto hammer & sledge hammer, grout the scored edge of house keeping pad afterwards.
