30 amp in-line fuse continually blows
Boy do I need some help! Every time I try to extend the landing gear on our 5th wheel when hitching or unhitching the 30 amp inline fuse blows after a few seconds. We had this problem a few years ...

1. Install a 30 amp auto reset Circuit breaker. CHEAPER than replacing fuses.
2. I(F you are positive that the ONLY item on that 30 amp fuse is the landing gear, then the motor is probably defective. IF you have other 12 volt items on that fuse then the accumulated amp draw may be blowing the 30 amp fuse. Doug
The only problem with auto reset circuit breakers is that some designs will weld the tips and take out the harness. I'm speaking of the clicker style that is basically a metal arm that heats up and pops open. When a fault occurs and they sit and cycle over and over and can end up welding the tips. Just mentioning it. The only breaker I would use would be a manual reset. If it pops maybe it's a one time thing, if it does it again find the problem.
Well, I have 36 years of working with and seeing Auto reset Circuit breakers in action. NEVER had a problem with what you state. Possible? Yes, but never had it happen where the Auto CB welded closed and that caused a burned harness. Doug
