Greeting all,
Reading Jan.Top-30 posted answer and question I found one thing about High leg and it is NEC artical [408.3(F)].
If a 4-wire, delta-connected, three-phase (high-leg) system supplies a panelboard, the high-leg (or wild-leg) conductor which operates at 208V to ground must be terminated to the ?B? phase of the panelboard.
It is a new thing I have heard but I am really interested to be clear more for me.
My question:
1- Is this only in delta connection or in wye connection too?
2- What is the doing advantage of this?
3- In delta 3ph 208/120 how one phase should be 208 volt and why it is not in wye connection.
Is there any explaination reference except NEC regarding this.
Hope to advise me soon.
