Stopped using the electric switch - used only propane and it never happened the rest of the week when using microwave and A/C.
Anybody else have these issues? I thought the electric hot water heater was a great idea to save propane. But if I'm having to worry about drawing too much power than it's something that I will never use.
You most likely have a 30 amp RV....and thus are limited to 30 amps of total power. As you have found out, running all three at the same time puts you over the 30 amp limit.
has this issue with 30 amps, and thus have to turn something off. Just a microwave and Air Conditioner can get you close to your 30 amp limit.
You have to learn what you can and cannot have on at the same time......as we all did.
Here is a chart that shows average amp draws for common things in both 120 volt and 12 volt.
normal appliance amp draws
and more reading:
and lastly, but often overlooked is the converter which converts 120 volt AC to 12 volt DC. If you are running a bunch of 12 volt things that are being powered by your converter, it also needs more 120 volt AC power to convert over. This will also affect what you other things you can or cannot have on at the same time:
It shouldn't take you too long to get it figured out. Easiest thing to remember is that your air conditioner is usually the biggest energy user...then about anything that makes heat is second. Microwaves, electric water heating elements, electric space heaters, electric toasters/ovens/skillets, and hair dryers need many amps. Your fridge on 120 volt uses several amps itself.
Now, just to complete the subject, you can use electrical adapters and plug your RV into a 15/20 amp receptacle, like your house has. When using an adapter like this, you are going to be limited to even less amps....which would be 15 or 20 amps.............and using even less electrical things at the same time.
