Hi DDW,
Sorry. I misread/misunderstood your original post w.r.t the existing 2-pole breaker. I thought it was off-boat at an extension of some kind. Sorry, again.
Can you elaborate as to the minus(es) of a 2-pole breaker, other than additional real estate, additional cost, and maybe some more wiring involvement? I'm not sure that I see the risk.
I can't say I've ever seen someone put a low-amp breaker between the neutral and grounding conductors. I understand the idea. But, an ELCI breaker seems like the perfect tool to guard against that situation. And, it also guards against a bunch of other dangerous stuffs.
Cheers!
