A transformer is fed from 2 legs of a 3-phase 480V, the secondary is 120V. The transformer comes with a guard for the 480 side but there is no guard given for the secondary. Would a guard for the secondary only be required if the unit was installed outside of an enclosure? My understanding is that the transformer is placed in an enclosure with other equipment the terminals of both primary and secondary could be left unguarded per NFPA 79 6.2.3. Is this correct?
Thank you!
