Can You Run the RV Air Conditioner on 15 Amps?

Absolutely yes because this can be achieved under some conditions put in place. The first thing you are required to do is identify if the connecting outlet is fifteen or twenty amperes. You can see markings of the readings in the circuit breaker. Using the correct measurements helps you run the RV air conditioner with ease and with more safety precautions.

Based on the alternating current you use, fifteen amperes can lead to an issue of blowing out the circuit breaker. But a twenty-ampere circuit enables the user to perform operations with other appliances when running your RV without tripping the circuit breaker. It does not matter whether you use a 15 or 20 amp circuit breaker, what matters is the number of other appliances you plugin.

For better maintenance and safety precautions it’s good not to plug in any other appliances to the same outlet of the alternating current. You can incur issues or even damage to your appliances. Remember this is the best article for all classes of people, whether you are new or familiar with air conditioners. Furthermore, you can also check how you run the RV air conditioner on 15 amps then, frequently asked questions, and lastly, the summary of the whole article.

Are 15 amps enough for an air conditioner?

Knowing the electrical requirements before purchasing an RV air conditioner is a great step. It is even better to know that electrical appliances like RV air conditioners have more power than home appliances. This is because of the more tasks they perform to work properly.

115,125 and 220 volts are the several readily available ratings for RV air conditioners. Their amperes ratings run from 15 to 20 amperes of current. The last two lower voltages ratings mainly occur in small units and large units have a higher rating. When the ratings are above 15000 BTUs they require a 220-volt circuit to run the process.

An RV air conditioner with smaller units with 15 amperes and 115 voltages runs a standard home outlet because at home we have small power-consuming appliances. In the case of higher units having higher energy need powerful consumers to handle the current produced.

When you want to perform a replacement of your RV air conditioner you need to look at some of the key aspects before purchasing a compatible machine. Some of the aspects include wattage, voltage, and ports. Take note of that before making any order.

The ports are usually listed by the National Electrical Manufacturers Association (NEMA) giving out the appearance and the best cable to be inserted. Extension cords are at times applicable but the compatible one is the best option. Before using your window RV air conditioner kindly check the wattage, voltage, and amperage before use. Moreover, this acts as a safety measure for your gadgets.

How many amps does it take to run an RV air conditioner?

How many amps does it take to run an RV air conditioner

A user using an RV AC will sometimes wonder how much amps your machine will consume. For instance, you as the user, like spending most of your time operating on the machine is good to know it brings more comfort to you. The reason behind this is that you are able to keep your electrical equipment. And so ensuring the right amount of electricity is the deal.

Shore power helps you to run machines like RV AC, television, toaster, microwave, and other electrical equipment. Others refer to 12-volt systems. This works together with the inverter. Every person using the electrical appliances should be able to know how much amperage each machine can consume.

Getting to know the exact amount of amperage used by your electrical appliances in the vehicle can help to prevent the tripping of circuit breakers. Remember most of these kinds of vehicles are wired to a 30 or 50-amp help desk. Provided you are using electric power in your vehicle; it consumes large currents that come from the shore power pedestal of a 120-volt.

Can you run a 13500 BTU air conditioner on 15 amps?

Different BTU values of the RV air conditioners in comparison with amps and watts

BTU valuesStarting wattsRun-up wattsAmperes needed
50001250-1450350-4504 Amps
70001550-1750550-7505 Amps

135002650-28501050-125010 Amps
150003350-35501350-165010-165 Amps

The connection is possible but nothing more than you should expect because the wires you are using will heat up consuming the maximum amperes recorded hence even fires can erupt. It is always advisable for safety to plug your RV air conditioner into the compatible 50/50 or 30/30.

The first thing to do is to identify if the connecting outlet is 15 or 20 amps. To know this just check the circuit breaker and you will be able to see the measurements. From my experience, I can say to prevent damage to your home appliances uses a 20-amp.

You can decide to calculate the amperage of the RV air conditioner. After that do the conversion using the different adapters. For example, if you want to convert a 60 amperes RV, use a 30 amperes male to 60 amperes female adapter. Then, complete the connection by plugging into the outlet of electricity with the help of a heavy extension cord I use with the RV air conditioners.

Can you run a 30 amp RV on 15 amps?

Is this possible using a 30 and a15-amp 125 Volt Straight Adapter? A fifteen amperes outlet can produce a maximum of 15 amperes electric current and not 30 amperes that many people misinterpret too. Because when you use a 30 amperes connection you are doing what is called overcurrent.

When using the 30 amps and 15 amps outlet, the device forces the 15 amps outlet to produce 30 amps which are not required. The wires and the outlet can only handle 15 amps any amount more can cause burning. For safety and proper maintenance of your equipment, it is advisable not to do so at any cost because it can destroy the whole system.

Sometimes if you have to use the equipment then it is good you convert your 30 amps to 15 amps service. After that, then you can connect directly to the standard three-prong plug. The 30 amperes RV needs a 30a female to 15a male. It is good to disconnect the 30 amp plug from the generator port.

Frequently asked questions

1. Is it possible to add Freon to the RV air conditioner?

When you open the charge valve, allow the Freon to get into the air conditioner for about a minute. Gently close and open after a minute to see the gauge observation. To reach the expected level of temperature in your RV do it several times to attain it.


After reading my article above you will understand how the 15 amperes can run the RV air conditioner. Moreover, the amount of current needed to activate the RV AC. It is good to know the amount of current and power your machine will need before powering it or else it can cause damage.

It is advisable to read the manufacturer’s specifications to help you have a simpler operation. And also help you find a good and compatible replacement for your appliances. In case of poor connection contact for help from an expert.
