50 amp lippert hydraulic upgrade

[Jackamills]

We have a 3120rl and upgrading the lippert 50 amp breaker to an 80 amp where is it located?
Thanks for the help

In my rig, it was mounted to the back wall of the battery compartment just above the battery box.

There are lots of threads on this subject. Daryles has posted some very good pics in the past. Here are pics of my front compartment. It is my opinion that front compartment wiring is similar on everybody's unit - but it looks different (if that makes sense!). Mine is a 2018 model.

Find the red positive cable traced from the battery to the hydraulic pump. That is the line you need to find to replace the 50 amp breaker with an 80 amp breaker. The 80 amp breaker was ~$40 on amazon when I bought mine. I am sure other folks will chime in with helpful info.

Leave the 50A breaker alone.
Just add an 80A breaker and put the hydraulic system on it.

Before you start, post a picture of your current setup. Some have discovered they incorrectly wired the Circuit breakers from the factory.

Forget worrying about the color of the cable, as many rigs came with black positive cables and white negative cables. When you upgrade the breaker to the 80 amp one, be aware you will need to enlarge the hole in the ring connector if you don't replace it because the studs on the 80 amp one are larger in diameter. This is ours with the new 80 amp breaker. Notice that there are two cables on the load terminal, and one goes up to the hydraulic pump motor and the other goes down toward the inside electric panel via the battery disconnect switch. This works because you rarely are operating the hydraulic pump when there are loads on the inside panel 12 volt side. Also, you don't say what year your trailer is, but the 80 amp upgrade is only applicable when the cable size is #4 strand copper. Smaller diameter cable will not handle the higher amp rated breakers.

Thank you all for your input and help
I installed in line the 80 amp breaker attached Are photos of the wiring in our rig
So you can see if wiring is correct
Again thank you all so much for helping me out

Looks good

Thanks for your help
I am going to replace both 50 amp breakers while I'm at it I believe the one one the right has failed no continuity across the breaker

[Daryles]

The one on the left is a 50A self resetting circuit breaker.

The right red self resetting circuit breaker 12v, 30A. It has 10 gauge wiring on circuit breaker

Blue: trailer brakes
Tan: tank heaters
Purple: slide control switch
Red 1: Power from 7 way cable/truck
Red 2: Power to Level-Up control panel
Red with inline 30A fuse: to solar MPPT


The 4 gauge wire interconnects the breakers, batteties and goes to the converter, hence 50A.

I was not sure on that thanks for the information
