30 amp for duel AC

If I have interpreted the OP correctly, they are asking if the camper can be run on a 30 Amp park service. If the camper has 2 AC units it WILL be wired for 50 Amp.

Having assumed the above, a 50 Amp camper can be plugged into a 30 Amp service but without a power management system he can only run one AC at a time.

We've run 2 on 30 amps service. Usually total draw was around 26 amps total for the entire coach when both were running. TV and items like that are fine to run with them but another large draw like dryer would cause one of the ACs to get turned off.

So yes it can be done. Depending on how the coach is wired it may or may not be possible. That can always be changed though.

Run, yes how much do they draw on start up? Typically they will draw 4 to 7 additional amps on start up, so if they both start up at the same time, your out of luck! Also at 28 amps total, you leave nothing to run anything else!

OH, and one more thing, 50 amp is in reality 100 amps, you have two hot leads, L1 & L2 each drawing 50 amps! The reason it is 50 amp service, is the circuit breaker is tied together, so you can not exceede 50 amps on either lead. 50 amp gives you so much more, go with that option if you can!

I can run both on 30 Amp, but that's all you can run. Which is fine, if need be.

Obviously one would prefer a 50 AMP connection but sometimes they aren't available. I've done it in 90+ deg temp and 90+ percent humditidy.

Anyone ever install a separate circuit on a remote breaker box for a 110 service? This was a recommendation from a mechanic working at a well known camping center. Then the bedroom A/C would be on its own 110 circuit and plugged in to the 30 Amp for the main 5th and a sep heavy duty extention on the post

Keep in mind a 30amp is really only rated for 25amps continuous. Drawing continuous 27-28 amps is a good way to burn out equipment. If you are lucky it just trips the circuit breaker.

You may or may not be able to get both units going but it's really a not a good idea.

I have two 15K ac units. I also have a power management system. It depends on the power supply at the park. If your power is clean as I call it, yes you can run two 15K units at the same time. I have done it but not at every park. Just assume most of the time you won't be able to do it.

This ^^^^ is a very viable idea.
THe gadget below is designed to do just that it will allow you to run both AC's on a 30 amp site

I have an RV SafePower Switch. It allows me to run both AC's on a 30 amp site. Work like a champ

How does it hook up? It looks like a manual transfer switch that's very expensive.

They make a dongle that plugs into the 30a connection and also the 20a on a regular power pole but from what I have heard if the pole has a GFIC they don't work. OR if the pole only has 30a going to it.
