Hi, I installed a 30 amp self re-setting circuit breaker on my tongue jack.

My jack is still blowing fuses.
I believe it is blowing fuses because the jack post and housing is bent.
The trailer is at an RV repair shop now.
If they can't bend it back straight I will get a new jack.
It never blew fuses before I bent it.
It got bent trying to jack up the truck and trailer stuck in the muddy yard.
It is not designed to lift that much weight.
The weight of the truck and trailer kept rolling against the jack post as it sank into the ground.
There is a 4" piece of concrete and a 6x6 block of wood completely buried in the ground from that incident of slick, slimy, soft, squishy Mississippi Delta mud.

I don't like self resetting fuzes, as blowing fuze and auto reset could cause further damage to item connected to.

Just being technical, but MDL fuses are not rated for DC, only AC. MDA fuses are rated for both AC and DC.

The original Super Jack by H & H Engineering a division of Barker was a glass slow blow marked 30 AMP 250 VAC.
I couldn't find them anywhere.
I bought a pack of 30 AMP 32 VAC at Advance Auto. The fuses blew.
I called Barker.
They sent me 3 of the original 30 AMP 250 VAC fuses, which also blew.
The problem with my jack is the bent jack post putting it in a bind.
Get the post straightened out or getting a new jack will probably end the blowing fuses.
The trailer is at an RV repair shop now.
In the future I don't really think it will matter if I get the 30 AMP 250 VAC fuses from Barker or the 30 AMP 32 VAC fuses from an auto parts house. I guess the 30 AMP and slow blow are the main features.

If you have a 2016, you may have an Atwood jack instead of a Barker. Barker may use a special fuse. My 2016 has an Atwood and I took the fuse out it is a standard 30 amp glass fuse, not a slow blow. Check yours and see.

Hi, it's not a fuse; It's a circuit breaker with the same rating as the fuse, so it won't / can't cause any damage. I have been using these since the early 70's as a Lincoln - Mercury mechanic and never had a problem.

We had the exact problem on our 2017 Classic. The ground wire was attached to a screw with some paint on it. We just scraped off the paint, reattached the ground wire and it has worked perfectly ever since. So I'd check the ground wire. You need to fully remove the cover to do so but it's a 10 minute fix if that's the problem. Hope it helps

Try Ace hardware for fuses.

MDL 30 is the designation to ask a NAPA clerk. They will never find slow blow fuses or delay fuses on the computer. Technically, MDL are fine for DC.

Had to replace a tongue jack on my car trailer recently and found that the vast majority on the market are Chinese. I too use a 30 amp reset fuse. However, it doesn't make any difference how it's grounded or fused, the motors are crap. Be sure you understand how to use the crank to raise and lower your trailer before leaving home.

Hi, when my tongue jack failed, on the opposite side of the country, I was glad that I had a bottle jack with me to get un-hitched, so I could go buy another one. [tongue jack]

One last thought- If you change the design of your electrical system (AKA, using different components than originally installed) make sure that you know the potential consequences. Voltage ratings determine whether the fuse or CB can safely open the circuit at the specified current and time. DC ratings will always be much lower than AC. If not rated for DC?????

The length of the time delay on either fuses or CBs is important and must be coordinated with the protection ahead of it in the circuit, because you can potentially cause a fire in the wiring ahead of "your protection".

From my personal experience, CBs are never as reliable as fuses. They are mechanically activated devices. Large CBs are controlled electronically and yet they still protect the CB with fuses.

In the end, if you guess wrong and have a fire, it will be between you and the insurance company experts to decide whether you guessed right.

IMO Never guess.
