In this graphic it shows the SBJ missing. And says parts can remain-energized.
Am I thinking of this wrong? if you had a 120volt ground fault (line1) with a missing SBJ. The secondary WYE is left ungrounded. Therefore like a ungrounded 3wire delta. So wouldn’t the first line fault to ground just than be the grounded conductor of the system and not energize metal parts? Than the 2nd fault (line2) from opposing leg (phase) would be 240volt to ground?
