I have a 44AC and have been having trouble with line 1 circuit breaker continually tripping. Admitedly it is hot in southern FL, and the water is warm, so may just be AC is working too hard and tripping. This only accurs when both AC units are working. I have checked out all electrical issues, and replaced the circuit breaker.No help. Also had AC units seviced recently. Has anyone had similar problems in boats with 2 AC units?
