My Wellcraft Martinique's main 30amp circuit breaker for shore power is bad. the previous owner bypassed it so i didn't have any protection and I want to fix it. Problem is I can't find a replacement (which may have been the reason they bypassed it in the first place!) The OEM breaker was a Carling Switch AB3-X0-00-739-3D1-C. I contacted Carling and they said it was a proprietary switch and that I need to contact the manufacturer. Wellcraft doesn't make this boat any more so I'm at a loss as to where and get a replacement breaker. it's a 3 pole/1 actuator switch. A search on the internet doesn't show many 3 pole breakers - I could only find 2 pole breakers at west marine. If someone can point me in the right direction it would be greatly appreciated.
