Had guys changing out small transformers for drinking fountains today and noticed they didn't install system bonding jumpers. Wired as follows:
480V 1? primary
L1-H1
H2-H3
L2-H4
120V secondary
X1-X3-Hot
X2-X4-Neutral
I caught this before energizing, installed SBJ now X2-X4-grounded conductor.
So this got be thinking about GFCI performance had the neural remained floating. Would a GFCI receptacle have a hot and neutral reference? Would it work?
