Electure:
Recently (doing private insp) came on a 250 volt, 200 amp (fused) disc as the primary OCP for a 480-120/208 xfr. YES it had 200 amp, 250 volt fuses, and YES it was connected to a 480 volt, 225 amp CB in the building switchboard.

Looking at the secondary....flex to a 6x6..tap to a 200 amp MCB panel (120/208) & tap to 200 amp fused disc for compressor rack. No Grd on XO, or anyplace else, except the piece of #6 ty-wrapped outside the flex, & wrapped around the flex conn screws.

A bomb waiting to blow. I guess the 'terrorists' are masquerading as 'lectricians ??? Osama Power????
