I'm not sure what is used on the electric systems, but pretty sure not heavy enough for a larger breaker.
Thanks, I suspected as much but thought I'd ask.

I have been checking, and the prices of Bussman CB185-80 Surface-Mounted breakers are running around $30, plus or minus, depending on availability and quantity purchased. These are not auto-reset breakers, but since I installed the one in our rig seven or eight years ago, I have never had a need to reset it.



So, if there is any interest for me to do this, please respond to this post so I can order enough breakers in time before the rally. If someone already has a breaker or if one wants to purchase a breaker on their own, that is fine also. Just post that info so I can be prepared.

I'd have anyone interested be responsible to purchase their parts ahead of time, so you aren't getting stuck with a bunch of circuit breakers.

Thanks, but I doubt there will be any problem being stuck with them. Even if I did have some extra, not installed, I'm sure that future rallys will use them up. I might even plan on having a few extra so I can do this at Quartzsite.

We are going to have to cancel this years rally due to medical issues with my wife Betsy. We were really looking forward to seeing everyone again.
Hopefully next year.
Have fun!

I have informed the park of our cancellation.

Sorry, I will not be attending the fall rally, but there will be many there that will be able to assist you with this project, just have to ask.

Fireman47, look me up at Rally and I’ll help. You could also have Keystone do it as part of your tech visit.

For anyone doing the breaker upgrade, I found this tapered reamer the perfect tool to enlarge the holes in the ring connectors so they will fit the larger posts on the 80 amp breakers. Attempting to use a drill is a disaster and can cause injury as the drill bit will grab the copper ring without drilling clean through and twist the ring connector. I got mine on Amazon.

Having watched Bob use that tool on my rig made me a believer. Yet another tool for the arsenal.
