CB issue

[Skyboss]

Hello everyone, this question is for the belectrically inclined. I have a Mainship34 Pilot and on the salon breaker panel the "engine" CB sometimes has an issue staying "on" only when initially placed into position. Any ideas? This is a CB and not a switch right? Do they wear out like house CB's ? And could I swap it with another less important from same panel? TIA

4x yes.
The rating if not on the face is printed on the side. Readily available at any Marine Supply or internet.
In Marine systems they often get used as switches which shortens their lifespan.

Amazon has them too. Search "blue seas circuit breaker". I look there first for just about everything.
