I can't remember, maybe we discussed this before...why do you think my newly installed seperate a/c breaker kept tripping this past weekend till my wife remembered that we had to put the refer on gas last trip...doesn't the refer have it's own dedicated breaker? it must share with the refer? any help appreciated...and any ad- or dis-advantages in using a 50 to 30 amp pigtail?

Newly installed a/c breaker tripping? Probably more to do with breaker than hot water heater. What else is on in the camper?

Need more information to assist. For 2 air conditioners to run at same time as other appliances like refrigerator and water heater, you need to be on 50 amps. What is the size of the new air conditioner? Did you get a power saver model? Sounds to me like the second air conditioner is not on a dedicated breaker or you have a wiring problem. One should have nothing to do with the other.

The a/c should be the only thing on the 20 amp circuit breaker for the a/c. I am a little confused by your post. Please clarify exactly what is tripping and why the refer would have anything to do with the a/c breaker?

OK, I'm back home now...It is the original 15k a/c on my 30 amp service camper....Lasy year I replaced the original 30/20 amp breaker with seperate 20amp and 30amp breaker...the 20amp a/c breaker was continually tripping till I switched the refer to gas....I have no idea why this worked...any ideas, maybe just a weak breaker?and just coincidental?

One way to find out if the refer is on the same ckt. breaker as the a/c, turn off the a/c ckt. breaker and see if the refer goes off when its on electric. If it doesn't then it was a coincidence.

Dale , I did turn off the 20amp a/c breaker and the refer stayed on , but I wasn't sure if it was on a 12v system or some other way stayed on...I dont think it should hav anything with the a/c but am not sure why the a/c stopped tripping when I switched to gas on the refer...think I need a new breaker?...

The refer is Gas or AC, not 12volt. You should be supplying 50 amp to run 2 ac units. Not sure but you could simply be drawing too much load at 30 amp and the AC trips 1st. Others with more input will offer advice I am sure. Good Luck

I wondered about that...do you think its the 20amp a/c breaker tripping because of total camper amps too high? Seems the 30 amp should trip first, I think...I dont know...the 20 amp breaker was inexpensive so I might just change that first...

I agree. Change the breaker first. The only 12 volt the refer uses is for the control board and this would be a very small current draw. I agree refer is either Lp or ac otherwise.
