That room looks a bit low its hard to tell. IF this was resi the Highest breaker handle
could only be 1.7 meters off the floor, it doesn't look resi to me though [Linked Image]

Plus i think the minimum headroom is supposed to be 2 meters if this is service equipment.
its hard to tell with the pics.

That wouldn't be an empty nmd connector that i can see is it [Linked Image]
