Why didnt this fuse trip

The other thing people don't realize is breakers have a time associated with them as well. So a 15A breaker will take a lot more than 15A for a very short time - milliseconds, before it will trip. You need to look up the curve for your particular breaker - if its published - another problem IMHO. That very short but very high current can easily be enough to fry electronics - which is why you need surge protectors.
Anyone who doesn’t realize this shouldn’t be troubleshooting this issue. They should calling someone who knows what they are doing. Also, he said it’s a fuse. Fuses can be time delayed, but it’s not the same as the characteristics of thermal magnetic breakers which you are referring to.

He also said that the fuse panel is "newish about 5 years ago".

Exactly what fuse panels were still in production 5 years ago?
 
Why would a sump pump be on a fused disconnect? Why would the OP refer to a fused disconnect as a fuse panel?
It absolutely should be a breaker panel. I said in an earlier post there isn’t enough info to troubleshoot this. Everyone is just guessing.

He probably needs to call up someone to come look at it instead of posting an extremely generic question on the car forum.
 
Sorry for the confusion it is a circuit breaker.....
What size circuit breaker is it? Do you have the motor nameplate info? What size wire is on the load side of the breaker? How long of a run is it? Have you tried swapping breakers with another feeder to see if trips - maybe you have a bad breaker? Did you check the terms to make sure everything is torqued down?

I have seen stranger things than that . I saw a lighting circuit for a China Cabinet that was tapped off of a 60 amp stove circuit . And they used 18/2 Bell wire .
