Hi; we're going on our first overnight camping trip tonight in our newly purchased (but used) motor home. The campground has 30 amp and 50 amp spaces. I'm trying to find out whether I can plug in my 120-volt coffee pot and am unable to find an amp to volt conversion anywhere. Anyone know? I've read posts on here stating you can't use a coffee pot, except for the stove top ones. Thank you.

Our 96 Southwind has 30 AMP service. When plugged into shore power I use the coffee maker with no problems.Either I don't understand your question or, you're overthinking the situation.When you are on shore power, all your 120 volt appliances will work. Maybe not all at the same time but, they will work.Enjoy your first trip and use it as a learning experience. :)

CarlKat,Welcome to the forums.Your Triple E will plug into shore power and then you will be able to use your coffee pot.If you wish to use the pot when trundling down the highway the options would be to run a generator (if so equipped) or add an inverter (which would draw power from the "house" batteries).

Carl, read articles on RV electrical systems. It's not complicated and then you'll be set for adventure!

You need to work with WATTS, instead of volts and amps. Your voltage will always be fixed at 120 volts so it is a simple formula to calculate what you will need. Power(WATTS) = Volts(120) x AmpsLet's assume that your coffee maker uses 1200 watts, that would mean that 1200 watts = 120 volts X 10 AmpsAll appliances are marked with the power (WATTS) that they use and if you use the constant 120 volts you can always tell how many amps your appliance will use. Adding all of the Amps up you can tell if you need a 30 or a 50 amp outlet.

30 amp shore power will give you about 3600 watts.A 50 amp shore power will give you about 6000 watts on each leg for a totalof about 12000 watts.A normal electric coffee pot is about 1200 watts.

"plugged into the camping space 30 amp area."

After testing and with surge and low voltage protection?

You need to remember that the converter to operate the 12 volt system and to charge batteries needs to be figured into your load. It activates as soon as you plug the rig in. Some converters take a short period of time to get the initial charge. This can reduce your wattage that is available.

As you've now experienced, your coffe pot will work fine. You have a 120VAC-30A rig. Plug into a 120VAC-30A pedestal. If a 120VAC-50A pedestal is all that is available, then simply purchase an adapter (male 50A/female 30A) and plug in as normal. In either case, anything that you would typically plug in at home will likely work fine plugged in in the RV. Just be aware that high draw items (A/C, microwave, hair dryer, etc) may require you to limit their use to only one or two at a time on your 30A RV.

(For those purists out there, yes, I understand that a 50A service is "technically" 240VAC; no need to jump in here. For the OP's purpose/question, that is completely irrelevant.)
