Welcome to the forum...

It does not seem to be a violation, but I have to reserve the right to rescind that opinion should there be any relevant facts omitted from your description.

That said, ask your AHJ... they have the final say.

I think that if the equipment is wider than 6 ft, and I assume it is, that the 5' depth you have is not enough to double the normally required depth, determined by the material of the surface facing your equipment.

The conditions of 110.26(C)(2) is (a) or (b), not both. The double-width condition you cite is part of (b). What about (a)?

Yes, I was wrong. I forgot about that.

Then unless we nit-picked about a potential obstruction from any hinged front on the equipment, especially with the hinge on the left, which may not exceed the clearance remaining from 5' anyway, it does seem ok.
