Utility Vault Clearance
Utility Vault Clearance
(OP)
I have searched both the NESC C2-2007 and the California General Order No. 128 concerning any required clearances above utility subsurface enclosures installed on private property.
This specific application involves a utility subsurface building tranformer room installed on private property in the basement of a large mixed-use commercial building. The building transformer room has a 5' x 8' hatch located at finished grade outside of the building first-floor footprint. In the infinite wisdom of the architect, a second floor patio has been installed above the hatch, with about 8' of clearance from the hatch to patio. I want to tell the contractor to remove the patio, but wanted to support my request with a code reference.

Code or not, it's not usually a good idea to make outage repairs involve major demolition.
