Electric tongue Jack blows fuses

Dont think in all my years I ever saw a jack with a fuse. I just put an electric jack on my car trailer and the instruction had me wire directly to the battery. My landing gear on my 5th wheel has self resetting a circuit breaker in line but thats the most I ever saw

What y'all are saying makes sense.... But,this is my 4 tt with electric tongue jack over 20 years and this never happened. This isn't some new behavior of mine that suddenly appeared. 2 Atwood jacks and an ultra-fab 5500 prior to this Barker. If the other jacks had behaved this way, I wouldn't have this this **** habit. I guess this is a character builder, eh?

If you get tired of replacing fuses, you could install a 30 amp self-resetting DC circuit breaker instead.

My electric tongue jack failed me in very cold and wet freezing rain when wind chill was below freezing and my crank handle was missing so I later removed the jack and relied on only hand cranking with better results anyway with no more worries or hassle. Hand cranking was good for my health and increases already really good character and patience. Cheers to common sense.

yup. same thing on my atwood jack, my smaller barker ball screw and my barker 3500 ball screw and on my max air fan.

basic analysis of electric motor principles of operation will show a much larger than normal current draw with motor running in the reverse direction when voltage is applied.
