From the 'oh, bugger me' files

Our boat has three a/c units. Never do we run all three at once, even with guests aboard.

But, last night, in the middle of the night the breaker to these a/c units kept tripping.

On a boat, if you have something electrical that keeps tripping, be concerned first and then very concerned soon after.

Nothing will ruin a cruise like a boat on fire.

Tim turned on the generator and started running a/c from it (bypassing the shore power breaker).

And yes, no breeze, 90 degrees and mosquitos from hell, we were running our a/c.

So, diagnostics begins.  First start at the scene of the crime....the breaker and whoops, there it is!
Fried wiring on the breaker.  Looks like the connection had worked loose, and when you have a high load situation and loose wiring, it's a gonna heat up in a hurry.  Bad, bad news.

Luckily, (on a Sunday, and a holiday to boot!) we were able to get a guy over to rewire it to get us through this trip and we'll get it totally rewired and redone later.  When we are not here, we don't run any high load items.

Moral of story, make sure all wiring connections on boat are clean, tight and not overheating.
