While true trailers with dual AC units have 50 amp service, I may have learned the hard way in the past that the combined load of refer, water heater, power converter, microwave and AC unit is way too much for a 30 amp service.
According to my Jayco owners manual:
AC: 18 amps
Water heater: 12 amps
Refer: 6 amps
Power Conv: 8 amps
Microwave: 12 amps
Total load: 56 amps
Now I'm not saying I had all these things going at the same time. But it gives an idea how quickly a few of the common things can add up to almost double the limit of a 30 amp service.
Anytime I plan on using my single AC in the future, I'm going to use 50 amp service if available. If not, AT LEAST
the water heater is going to get switched to gas.
