We are installing a customer owned <500gal mineral oil XFMR with 13.8 primary on a concrete pad outdoors.
What is the clearance from the side of the metal building (locked entrance property) to the side of the XFMR (non-access side, non-cooling side)?
From what I understand from reading 2023 NEC and browsing this forum, this seems to be an insurance and/or, more probably, an AHJ concern more than an NEC concern.
