110 ac circuit breaker replacement

[Marnis]

Hello,

I have a 2018 Ranger 31CB. where would I get a replacement 20 amp circuit breaker for the ac panel? How would I replace an individual breaker on the ac panel? Your help is greatly appreciated.

I believe the panel is made by Blue Sea systems. They have a full catalog of switches that you can view online. The replacement of the breaker requires the removal of the panel. When you remove the panel I highly recommend that you inspect all connections. They do come loose over time or were not fully tightened when the switches were wired. I found my panel connections to be loose and located a number of burned connections caused by loose terminal screws.

I also found the main shore power receptacle terminals loose and burned. This was a week after taking delivery of our boat. The ECLI breaker kept tripping. Reed Yacht Sales tried to find the cause and told me it just happens? I then troubleshot it myself and found the cause. Terminal connections loose. At the same time I found that the main 120V 30amp cable going from the shore power receptacle to the ELCI breaker was a 12ga boat cable. This was to small in my opinion so I replaced it with a 10 ga. The cable from the ELCI to the breaker panel was 10 ga. I believe this was a bit of a QC issue. It happens!

Thank you so much for all your suggestions. I will check all the connections.
