240V wild leg panelboard

[electrofelon]

Thanks dungar for the clarification.

2014 NEC 240.85 Applications.


240-85 Applications was first added to the 1996 NEC.

I wonder how many 120/240V 3PH 4W Delta fed panels are still out there with 2P 120/240 rated breakers installed on the "B" phase wild leg?

I wonder how many of the 2P 120/240V breakers were still being installed on the wild leg after the 1996 NEC was adopted by AHJs.

Lots. Although I don't always check this on existing stuff I look at, I don't recall EVER seeing a straight rated 2 pole connected high line to line :blink:
