With nec 2008 adding definition for a neutral conductor as a current carrying conductor with non linear loads, we are exploring using four pole breakers in a variety of applications.
My question though, is possible unintended consequences.
Hoping folks here have some thoughts and opinions, the use of 4pole breakers for feeders to isolate the phase and nuetral conductors is somewhat non mainstream.
THANKS
Rob
