702.11 was 2008 the same for 2011 is 702.12...
No argument here. 702.11 has to do with grounding and bonding of portable units, which is not applicable. 702.12 has to do with outdoor generator units, and is applicable here.
The question that has been raised is whether the built-in disconnect is "suitable for use as service equipment" or not. Usually, this means that the disconnecting means can be configured for the neutral to be bonded to the ground to earn such a rating. I'm not sure about whether the unit qualifies to meet this requirement, this is something that needs to be investigated.
But then the question comes to mind IF an outside disconnect is required to be "suitable for use as service equipment" BUT since it's controlling a FEEDER which can NOT have its neutral bonded again, isn't this a conflict of requirements?
...As long as the transfer switch has a UL 1008 it would be compliant
I did manage to discover that the transfer switch is UL 1008 listed.
