6 Best 50 Amp Generators

In the simplest way to explain, 50 Amp generators are electricity devices that supply 50 amperes of current. The best 50 Amp generators can become very helpful in emergency times, such as power outages or prolonged blackout. They are capable to power an RV and various basic appliances like TV and electric stove simultaneously.

These generators typically run in at 8,000W to 12,000W. It is because in general, 50 Amp generators have double hotlines, in which each provides 50 Amps that result in a total of 100 Amps. When the number is multiplied by 120V, it produces 12,000W. It is about three times as much as power that you are able to gain from 30 Amp outlets with one hotline, which results in 3,600W.

The capacity to produce such a huge power are what makes the best 50 Amp generators perfect to run RVs and other high wattage appliances in the same time. For example, when you power an RV, a 50 Amp generator lets you to operate two ACs at the same time. Another instance is when you can run coffeemaker and electric skillet all at once, and many other convenient benefits to get.

What Size Generator Needed to Run 50 Amps RV?

Majority of recent RV models nowadays require 50 Amp power supply to run. However, there are only handfuls of resort or park location that can offer this type of service – even fewer if you were to take the RV to more rural area. This is why it may be worth to look on the best 50 Amp generators in the market and invest on one.

It’s quite a tricky matter to determine the right wattage that your RV requires. The exact power measurement depends largely on your appliances’ ratings and how many of them you need to run simultaneously. It’s safe, however, to assume that a 50 Amps RV will need at least best 50 Amp generators with 4,000W of power – the higher you can afford the better.

What Appliances Can Be Ran on 50 Amps?

Conducting the electrical matters of your RV means to balance finely between the amount of available and the required amount for electronics and appliances. To get a sense of balance, you have to understand the basic of how things work and the amount of power used by your devices.

To a large extent, you’d be able to run most of your appliances at the same time, by plugging 50 Amp plug-in into 50 Amp socket. To have better estimation of the amounts of appliances you can operate simultaneously, here’s a brief list of how much energy common appliances actually use:

  • Small appliances (fan, vacuum, radio, DVD player, and television) use 3 Amps or less.
  • Medium appliances (electric skillet, coffeemaker, toasters, and food processors) use 5-9 Amps.
  • Large appliances (microwave, hair dryer, curling iron and hair straightener, water heater, space heater, and air conditioner) use 10-15 Amps.

Is It Possible to Operate 50 Amp RV on 30 Amp Generator?

Short answer is, yes, it is totally possible to run 50 Amp RV on a 30 Amp generator. This won’t cause damage to the RV. In order to do so, you’ll have to plug a 50 Amp female adaptor into a 30 Amp male adaptor, as this will let you to connect directly to the shore power.

However, you must keep in mind that to create this electrical connection, there should be a limitation on the amounts of appliances that can be operated simultaneously. For example, an RV that has two AC units is most likely able to operate only one unit at one time. There is a possibility that you would make the outlet burst out its circuit breaker if you insist to run both AC units altogether.

Some more modern RV models may incorporate AC units with higher energy efficiency, which means you might be able to operate two AC units on 30 Amps. That being said, you must not attempt to operate other larger electrical appliances such as water heater, hair dryer, or microwave.

As mentioned before, 30 Amp generator can server 3,600W which is fall in comparison with a 50 Amp RV that can give as high as 12,000W to use on various appliances. Majority of 30 Amp circuit breakers has around 20% of tolerance. Therefore, the maximum electrical energy it can pull is 3,600Wx120% = 4,320W – more than that, you’ll more likely to trip the circuit breaker. Not to mention, others that use the connection will leave you with less than 4,320W to use in actual.
