The Delta breaker deal has been, to my knowledge, a no-no for 2 or 3 decades.
There is confusion as to how the introdution of a third leg ( or in this case 2-A legs, 1-B leg ) was accomplished, simply because nobody is going to advertise this .
This makes it something of a curious oddity to newer trade members as I , who have really only been seriously involved at it since the mid-80's
Perhaps you could give us a little history thread on this sometime here?
PS- I wonder if that 2-pole GFI would work on A+A phase ??
