I have a situation where the RTU was installed too close to the edge of the roof. This is causing the building inspector to required a guard rail be installed and reduces our working space from 42" to 38" from the front of the VFD. This is a 480V 3P system.
My question is, what condition does this fall under? Is the guard rail considered grounded parts and requiring us to have 42" clear? or is the guard rail considered to be no grounded parts and requires us to be at 36".
I have not contacted the inspector as we do not have a solution yet.
Thanks.
