How many amperes does a generator produce? (500W to 30kW Generator)


With a generator, we usually only get wattage. Example: 5kW generator, 22kW generator, and so on. We don’t really know how many amps the generator puts out. To help everyone else out, we’ll look at how to calculate how many amperes a generator produces.

down, you a’generator amps calculator‘ And a calculated table How many amps do generators draw at 220V and 240V voltage (500W to 30kW generator),

Here are two pieces of information you’ll need if you want to find out the amps produced by any generator:

  1. wattage. It is easy to detect; Everyone knows how many watt generators they have. Example:
  2. voltage. This is the electric potential; Typically 220V, or in the case of larger generators, 240V.

You need to determine how many amps your generator draws. We’re going to look at how to calculate the amps for a 5,000W Honda generator yourself (using the basic electric power equation).

In addition, you will also find a ‘Generator Amps Calculator’ and a calculated table to help you determine the amperage of your generator.

How to calculate how many amps a generator draws?

If you know your generator’s wattage and voltage, you can easily use the electric power equation to calculate amps. Here is the equation:

P (power) = I (current) × V (voltage)

To better use this equation, let’s use power units instead of power, current, and voltage:

Watts = Amps × Volts

To calculate amps, we need to express amps like this:

amps = watts volts

If you want to calculate the amps generator draw, you need to divide the watts by the volts. Simple, isn’t it? Let us give 1 example before examining the automatic ‘Generator Amps Calculator’.

Example: How many amperes does a Honda 5,000W generator produce at 220V?

We know both wattage (5,000W) and voltage (220V). Here’s how we can calculate amps based on these two figures:

Amps = 5,000W = 220V 22.73 amperes

In short, the Honda 5,000W generator produces 22.73 amps.

To make things even easier, you can use the watts to amps calculator mentioned earlier for the generator:

generator amps calculator

You simply put in wattage and voltage (or use the slider), and the calculator will dynamically calculate the amps as the generator generates. You can also play with the numbers to see how this calculation works:

You can check the 5,000W Honda generator amperage above. If you slide ‘Wattage’ to 5,000W and ‘Voltage’ to 220V, you will get a result of ‘22.73 Amps’, as in our example above.

Here is the promised calculation table for 500W to 30kW generator capacity:
