Actually it's 80 amps - 24 amps = 56 amps since neither circuit should be loaded more than 80% for any length of time. Quote Link to comment Share on other sites More sharing options...

I agree that this would be the proper way to consider things, but I seriously doubt if many RVers worry about the "safe continuous load" on their electrical systems. They run as many things as they can until they trip the pedestal breaker! When it's summer and you have 2, 3 or more A/C's you just turn them on and let them rip!

podwerkz Posted October 24, 2019 Report Share Posted October 24, 2019 (edited) The Alante when equipped with two 11,000 btu units comes with a 'power management system' and/or an 'energy management system'... I can't find exact specs on this system but if it is like some aftermarket systems I have seen, I suspect it manages the two A/C units so that both compressors are not running at the same time. You should call or email Jayco and ask about it before you spend your money, especially if you plan to spend time in higher temperature locations.

noteven Posted October 24, 2019 Report Share Posted October 24, 2019 My 30amp Roughneck has an “energy management system” -it’s a switch - you select a/c or water heater electric heat.

When it's summer and you have 2, 3 or more A/C's you just turn them on and let them rip! You are probably correct, but the first post asked about the difference between 30A and 50A service. That breaker (like all such circuit breakers) actually has 3 trip points. They are long time, which means continuous, short time for such things as starting currents, and instantaneous, which is for a direct short or extremely high load. Typical long time trip setting is about 80% of the breaker's rated capacity. Quote Good travelin !...............KirkFull-time 11+ years......

I think you are right and this leads to breaker failure and burnt plugs. Depending on a single device to routinely keep wires from getting hot enough to burn and start a fire seems risky to me. Electrical codes have a minimum service size for this reason and many try to operate these same appliances in their RV. As I said earlier I think 30A service in an RV is just a way to cut costs, safety be damned.

Ours was a 15A popup to a 30A travel trailer. It seemed that we had power to waste! There will always be a legitimate market for the less expensive RVs that have only 30a. Our present 20' travel trailer could hardly make use of a 50A supply. Quote Good travelin !...............KirkFull-time 11+ years......
