NEC Work Space Grounded Surface

[xguard]

I have an Industrial Enclosed Outdoor Generator. There is a transfer switch facing it. I believe the space between the generator enclosure (metal) and the tranfer switch door would fall under condition 2 of 110.26(A)(1) for determining required work space. The transfer switch being the live parts and the generator enclosure being the grounded parts. The opposing view is that it falls under condition 1. I can't understand how a metal object sitting on concrete would fall under condition 1. Am I missing something here? I'm new to dealing with generators in this regard. Thank you for any assitance.

I would say that you are exactly right.
The metal parts of the generator and/or enclosure must be considered grounded.
Or are they arguing that the live parts of the transfer switch are effectively insulated? Not when you are working on it they are not....

Nor can I. This has nothing to do with generators. Metal on concrete counts as a "grounded surface."

I would agree
