Why did my 30A battery fuse blow?
I was hooked up to 15A service and may have used a bit too much power all at once, but no breakers tripped so I'm assuming I was OK. Went to hitch on to leave and my electric tongue jack wouldn't work - checked the 30A fuse and it was blown. If my power draw was too high for the 15A power source, would that somehow blow the fuse for the tongue jack? I don't know why/how it happened.
