How Many Amps Does A Rv Roof Air Conditioner Draw

So if you have a ac rated at 12 amps at 95 degrees then at 75 degrees it will pull 10 amps.

How many amps does a rv roof air conditioner draw.

Rv air conditioners are typically either 15 000 btu british thermal units or 13 500 btu although other sizes exist as well. Where as a 13 500 btu air conditioner will draw around 12 amps. This is basically the cooling capacity of your ac. A roof air conditioner can draw 16 amps to start but may only use 13 amps once it is running.

For example the roof air conditioner is on a separate 20 amp circuit breaker. There is a chance for it to increase depending on the number of the air conditioning units installed in your rv and their individual sizes. The exact value depends on the btu and the mode in which it is operating. All rv ac amp draws on the spec plate is based on 95 degrees outside temp.

A 15 000 btu air conditioner in rv on an average draws around 12 5 13 amps. The spec sheet is the actual amp draw for that unit at 95 degree outside temp so at 100 degree the correct actual amp draw will be 15 1 amps on hi fan. Easy start advertises it can reduce the current required to start your rv s air conditioning by 65 75. A larger fifth wheel or a class a rv generally uses 50 amp capacity.

For devices in the rv that require more amperage you will notice larger sized circuit breakers in the power distribution box. A 15 000 btu unit has a greater cooling capacity but will require more power about 5 100 starting watts and about 1 600 running watts on average. This reduction in power allows rvers to start and run their air conditioner with a smaller generator like a 2 000 or 2 200 negating the need to haul around a bigger generator like a 3 000 watt or run two smaller generators in parallel. If yours was not pulling 15 1 amps then the ac is not operating to its full specs and is not cooling as it should.

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. The amp draw does not go down after running. The typical rv is usually designed with either a 30 amp or a 50 amp 220 vac service that powers all of the electrical equipment and appliances the owner may want to use while camping. For instance a 13 500 btu air conditioner can draw around 14 5 amps when set in cooling mode and 16 amps when set in heating mode.

You add 1 amp for each 10 degrees above 95 and subtract 1 amp for each 10 degrees below 95. Even though the electrical power supplied to these rv s is designed to be adequate for the average family while they camp far too often the added equipment that may be used will overload the circuit breaker. It also depends on what mode the unit is set.
