Don it looks like you have connected your battery connect right to your motor connection. Battery connections should go to one side of each breaker and the load to the other side.To test just trip your new breaker and try pump. If it runs you have no protection.
Hi Travelinsparky,

I wanted to follow up on your comment. I pulled my unit out of storage this morning and I tested the CB as you described. The pump does not go on when the CB is tripped. Reset the CB and the pump came back on like it supposed to. Thanks for the follow up question.

Don

Because of the information that the members of this club has posted, Thank you all. My 3791rd is 2 months old. I live in Tennessee and it has been cold this winter. After the first month of owning our new rig I noticed the breaker for the slides and jacks was tripping about every 5 seconds of trying to open or closing our slides. Same with raising or lowering our jacks. I downloaded the PDF file from this group about Lipperts recommendations on the size of our breaker. Took it all to our dealer. After contacting Keystone several times the dealer replaced the 50amp breaker with the recommended breaker. Problem solved! No Charge!!!
Thanks y'all
Joe

I can't imagine any company would be crazy enough to tell someone to increase the size of the circuit breaker without making major modifications to all the devices involved. As for drilling anything out, that is usually a sign of making a bad decision. Manufactures design things to not allow someone to make unsafe changes. Another thing to be aware of, just because you buy a circuit breaker doesn't mean you are buying one to protect the circuit properly. There are many different types of circuit breakers, as an example: Thermal Magnetic breakers compared to Instantaneous trip circuit breakers. One is designed specifically to protect in case of a short circuit. Im not an expert on making the changes suggested and certainly in no way recommending anything, just someone that likes to sleep at night knowing my electrical system was designed and installed properly! Would love to know what official document Lippert may have sent to anyone that suggests these changes?

You don't say what rig you have, but we have a 2012 3402RL, and I believe it was one of the earliest units that had the hydraulic leveling system factory installed, and the wiring from the batteries to the pump and the power center is all #4 STR copper, so the 80 amp breaker recommended by Lippert is nowhere close to overloading the cable. The older rigs that have only hydraulic slides may have smaller cabling, so those would have to be checked before increasing the breaker size.

If you look at the upper breaker in the top photo, the battery side cable goes in and out on the same terminal and then to the lower breaker in the photo. The top breaker feeds small loads that don't come from the fuse panel. The two cables leaving the lower breaker are in the correct position, one goes to the pump and the other off the same terminal goes to the fuse panel.

DQDick, I just wanted to add my two cents, us non-full-timers, people who call themselves Longer-timers like us demand reliability too in the Montana just like the folks who live in them 365 days of the year. For the price we pay for these rigs, Keystone should always keep in mind our bests interests, weather "part-time" or full-time living. There are excuses for anything less from the manufacturer. Maybe they should allow a little more customization at the factory, like the heavy duty circuit breakers, or metal vacuum breakers rather than plastic crap they use, I would be glad to pay for it when the trailer was being built.

I noticed ours triping, being an electrician upgraded to 60 amp breaker and moved the ground from the frame straight to the battery and upgraded the wire to and from the hydrolic pump for less resistance. I also added more 15 amp and 20 amp breakers, added a disconnect to negative side of battery.

Hydr Pump Breaker upgrade

[QUOTE=carl n susan;1123895]I bet you have a residential refrigerator. That 150 amp fuse is for the inverter that supplies power to the refer. The self resetting breaker for the hydraulic system is totally separate. It looks something like this (the red one on the right is what a stock one looks like. The left one is an upgraded replacement):

[/QUOT

Can you advise what part number you used to order the self resetting breaker for the hydraulic system?

Based on earlier guidance I ordered the 80 amp busman but now have figured out that is the power line going to the inverter, not the hydraulic pump?

Can you provide me a part no. for the new pump breaker that your picture shows on the left side?

Also, can you clarify the wiring. You note the one on the right is the old config and the one of the left is the new. Wiring is not the same?

Thanks,

The setup on the left is an alternative to the 80 amp breaker. It is two 40 amp breakers wired in parallel which provides 80 amps overall

The two 40 amp in parallel is what I did as we were about to leave on a trip and I could not find an 80 locally and did not have time to order one. I just bought two 40 amp at a local auto parts store, two short buss bars at Lowe's, and some shrink tubing. That was 8 years ago and still works fine.

We don't know what the size of the ckt breaker is in our 13 3402.It is the OEM breaker. We had a 06 3400 that tripped the breaker if we tried to bring all the slides in with one push of the switch. This 3402 has 4 slides like the 06 3400. We are always on shore power when extending the slides and leveling jacks. We will bring in the bedroom and kitchen slides , let off the switch for a few seconds, bring in the opposing slide, let off the switch for a few seconds then bring in the main big slide. Never a problem with the 06 3400 or this 13 3402.It may add 20/30 seconds to the set up time but we are never in a hurry.

50 amp Breaker

Iíve been dealing with this past 2 days, then I remembered this thread. I thought what I was seeing was a wiring block and not a breaker, I tested and found one side had power and other didnít, I moved wiring over to same side and bam, it all works!. I had lost all DC power inside, as well as ability to charge batteries. Now my question. The ďother 50Ē is feeding the problem 50, if I replace with only one 80 then itís still getting its power from a 50 amp. Have I accomplished anything by making the one on the left a 80?

Check your wiring again. One 50 should not be feeding the other 50. The large wire from the battery should go to one of the 50s and then a jumper to the other 50 so that both are connected directly to the battery.

They must wire these trailers different every day depending on what day it is!!!!

On my 2018 3721RL, I have two different hot wires coming off the batteries. One goes thru a 150 amp breaker thru a on/off switch to the inverter. A second one goes to what was an original 50 amp breaker that ultimately feeds the hydraulic pump.

Two wires direct from the battery is even better than one wire and a jumper.

There was a recent discussion about a breaker vs a fuse to the inverter. Something else inconsistent.

You have two separate systems, one the wiring through the 150 amp breaker to feed the inverter. The other is a system of two auto cheap self reseting breakers. One feeds the hydraulic pump, the other feeds trailer needs.
