Listing of AMP usage?

[vetdame]

Happy Father's Day!

Getting closer to taking shakedown trip with new to us fiver.
I need to find a listing of AMP usage for appliances/equipment.
Living in Florida means the A/C is a must, so I need to know
what else I can run with it on. Am limited to 30 AMPs. ??

Hi,

You can also add an auxiliary shore power cord. I did two--one for my converter and a couple of outlets and one for my water heater. I used male and female plugs so I can switch back to OEM in a hurry.

I love having these tools for actual measurements.

If you only have a 30 amp RV with one AirCond (I do) or you are limited to 30 amp by the park service available power then:
- put your HW heater on gas
- becareful running Micro with AC running but we do it all the time with no problem
- only run 1 AC if you have 2 (50 amp RV powered by 30 amp service)

You will be fine this way

There are quite a few. Here is one.

Appliance Amperage

Wattage % Volts = Amps
Amps X Volts = Wattage

One other thing to keep in mind is many RV appliances require more amps to start the appliance than they do to run the appliance. A roof air conditioner can draw 16 amps to start, but may only use 13 amps once it is running.


120 Volt AC Amp Ratings

Here is a another one for comparison.

Appliance amperage

I hope this helps.

Hi,
You can check the amp draw of many things, and it is molded into the plastic. If you can not read the number, the eyes of a grandchild can help. It is typically tiny and in the plastic.

So the coffee maker might be 1,000 - 1,200 watts, or about 10 amps
toaster can be 8-10amps.
Microwave might say 900 watt output power, but typically will have 1,200 watt input power or about 11 amps
A/C units are about 11 - 14 amps each, with warmer days increasing the amperage.

On the RV, the refrigerator is about 3-3.3 amps, and practically nothing if running on gas - bonus is the gas cooling effect is almost double the electric heating element cooling capacity.

Battery charger is going to be around 1-2 amps, more at night when more lights are on.

TV is typically less than 1 amp with a LED screen, still a small load. VCR, DVD or laptop computer are all less than 1 amp each.

If you have a 30 amp service, then you might be able to run 2 A/C if you shut off most everything else, and only run the TV. While away from the RV, my suggestion is to only run 1 of the A/C units, because you will not be there to reset the circuit breaker - should it trip under a heavy load.

Also in some campgrounds it is a requirement to monitor the input voltage, and stop the A/C if the voltage is below 104 volts. Most will plug in a autobooster if below 110 volts, to bring it back up to the normal range. At 104 volts the A/C compressor will be drawing more amperage, and might trip on it's internal overloads. IT can also damage the expensive to replace compressor if running less than 104 volts!

Good luck!

Fred.

How many prongs are on your shore power plug? What number is on the main breaker in your circuit panel?
