Air conditioner

When camping during summer season and when I use my air conditioner the fuse get tripped often. I have to go to the fuse box and re set so the air will start. I do this a lot during summer camping. Any suggestions from the group to stop this from happening? Can the fuse be replaced with higher volt? Thank you

Is it a fuse (12 volt DC) or is it the breaker (120 volt AC)?
I suspect that it's the 120 volt breaker since you said that you can reset it.
Which breaker is it? The one that feeds just the A/C or the main 30 amp breaker?

Does it happen as the A/C is starting up or after it's ran for a while?

Does it happen at different locations or just in one campground?

When using the air conditioner I switch the water heater 120 volt electric off so it heats with gas only. If I’m using any other high drain appliance (like a coffee maker) I either switch off the air conditioner or don’t use the microwave until done with that device. With the water heater on gas and no other high drain appliance running, I am able to use the microwave while the air conditioner is on. I have the 13.5K BTU air conditioner; my method may not work with the 15K BTU unit.

Thank you itís the 120 volt AC. The one that feeds just the AC. The breaker inside the RV. It happens after its ran for a while. Then we will just switch the breaker back on every time it tripped. Itís happening on different campgrounds. Thank you

If the A/C is working correctly when it's running it could be a weak breaker.
The easy thing to do is replace the breaker with another one of the same rating and see if the problem goes away.

How old is the camper and the A/C?

Most likely loose connection at the breaker.

How are you turning off your water heater? Maybe you think it's off when it's not and as it cycles on and off it's overloading the circuit. Just a thought. If it's suburban, there's a power switch inside the door outside that kills electricity to it. Also, you can turn off the wh breaker inside.

It's pretty easy if you're handy. It rotates out from the handle side and slips off the retainer. Then you can manipulate it to where you can see the wire and lug to unscrew it. Swap the wire to the new one and plug it back in, in reverse of how the old one came out.

I like Siemens and Square D, but really any brand will do.

And... make sure you turn off the shore power at the pedestal before attempting to replace.

you actually probably only have a LOSE outgoing wire from the breaker...which heats up when the air conditioner is running, and eventually 'loses' it's connection, tripping the breaker(an arc)...

tighten it up and see what happens
