FIRE RATING FOR TRANSFORMER VAULTS OF 13.5 KV AND ABOVE?
(OP)
I would like to know what is the Fire Rating Criteria is for 13.5 KV and above Network Transformer Vault Wall Construction in the US. If it is addressed NEC [National Electrical Code in US], I cannot find it. Any Electrical or/and Building Standard code that address matter in the US will be greatly appreciated..

Is this an electric utility system network vault? If so, the NEC will not be applicable (in any respect).
