Understanding What a 30 Amp Generator Is

An AMP (ampere) is a fundamental unit of measurement for electric current, which quantifies the amount of power a device or appliance uses to run. A generator produces a specific amount of amps, according to its size. In this present case, a 30 amp generator can supply 30 amps of power.

Such generators have a lot of applications, including camping, tailgating, a backup power source for your home.

Several people make use of 30 amp generators for powering their RVs. The majority of RVs run on a 30 amp electrical system, which means you can only have so many appliances and devices hooked up at the same time.

If you‘ve too much power running through your residential vehicle, you can make the breaker trip to direct your power out.

To understand the working principle of a 30 amp generator better, do bear in mind that a 30-amp RV system makes use of 120V. By multiplying 120V by 30A, you’ll realize a maximum allotment of 3600 watts. Thus, all devices you’ve plugged in can’t go beyond 3600 watts.

For instance, if your refrigerator uses 400W and your air conditioner 1700W, you’ll have 1500W left to use for other appliances. Before reaching the maximum wattage capacity, you should be able to plug in a TV, phone charger, laptop, and some lights.

The same thing also applies if you get a 30 amp generator to power your RV or if you use it for your house.

But a modern home that’s a central air-conditioner and electric heater will usually require around 150–200 amps. So, if a sudden outage occurs in your area, a 30 amp generator will only be able to power few appliances in your house.

How to Find the Right Size Generator for Your Power Needs

To choose a generator, consider going for an option that’ll meet your electrical needs. Thus, the kind of generator you decide to buy should deliver enough power for the specific purpose you intend to serve.

For instance, if you intend to power your whole home during an outage, a whole-home generator is your best bet. However, if you just seek enough electricity to use your basic appliances, you could choose a 30 amp or 50 amp generator.

Generally, the more power a generator puts out, the bigger its size. For this reason, if you’re looking for a portable generator that’s more lightweight (around 50 – 80 pounds), you can expect it to supply around 2000 – 3000W. Larger generators on the market, which weigh about 250 pounds, can put out 5000W or more.

Again, what determines the right size generator to choose is your electrical needs. If you opt for a unit that’s too small, you’ll overload the machine and force it to give out more power than its capacity. And when this takes place, the generator will typically go off or overheat.

Thus, you’ll fry the generator and also damage your valuable appliances.

If, on the other hand, you select a unit that’s too large, you’ll be paying in excess for the machine and the operating cost.

For this reason, it’s essential to first decide on the specific amount of electricity you need before buying a generator.

Here’s how to do this: Determine the starting and running wattage of each appliance to be powered with the generator. These numbers are usually on the appliance label. If they’re not there, you can make use of the wattage estimation guide as a reference.

Now, add up the wattage, and from there, you can know the size of the generator to purchase.

Here’s an example to consider: Let’s say you own an RV with a 30-amp system, implying that it can’t handle more than 3,600W of power. Thus, you’ll need to go for a generator that supplies no more than 3,600W. If not, you’d not only be wasting money but also space.

30 amp generators are ideal for this kind of use case. This is because they can deliver enough power for essential electrical needs and are also light enough for you to unload & carry.
