Fuse for slideout

My FR Rockwood Mini Lite has a 30A fuse. It is located under the body of the camper. It is close to the front and on the driver's side, which is also the slide out side on my camper. It is a green in line automotive type fuse holder.

We have a fuse and a mini circuit breaker. IIRC, that's what Lippert shows on their wiring diagram. The mini breakers, typically in the A-frame, are very subject to corrosion as you can see in the above pic. The crimp connections on the ring terminals can also be poorly done at the factory. I had one where the wire fell right out when I touched it.

It's a good idea to go through all connections & splices in the A-frame. I ended up putting them all in a PVC watertight box including the circuit breakers.

If your RV was delivered in the winter, it could have been subjected to a lot of salt which the dealers don't rinse off. Our circuit breaker connections were badly corroded withing just a year due to this.

FWIW, you might want to check a few other exterior connections that are also subject to corrosion - the ground to the frame from the converter/panel and the mini circuit breakers for electric stab jacks. We have a breaker attached to the frame for our jacks right next to the motors.

Correct and the location should be as close to the battery as possible which is normal for high load equipment. A lot of times it's mounted to bottom of the trailer near the A-frame. Like mentioned above they can often be exposed to the elements and can corrode/wear out within a couple of years. When I replaced mine I encased them in liquid tape ... see pics below of before and after ...

Most times it will be within several feet of the battery. It may be mounted inside the pass through, on the wall, behind battery.

That autoreset breaker does wear out. I had one started to get weak a few years back and would only move the slide a foot or so and then had to cool off before it would work again for a foot or so.. I replaced the breaker and all has worked well since. I bought 2 so I would have a spare and still have the spare, but that is OK.

Possibly with a red rubber cover.

Slides have breakers, usually the auto-reset type. They hide them where ever it's convenient for the builder.
