# How Many Amps Does A Generator Produce? (500W to 30kW Generators)

With a generator, we usually just get the wattage. Example: 5kW generator, 22kW generator, and so on. We don’t really know how many amps does a generator put out. To help everybody out, we’ll look into how to calculate how many amps does a generator produce.

Below, you will also find a ‘Generator Amps Calculator‘ and a calculated table of how many amps do generators draw at 220V and 240V voltage (500W to 30kW generators).

Here’s are two pieces of information that you will need if you want to find out the amps any generator produces:

1. Wattage. This is easy to find out; pretty much everybody knows how many watt generator they have. Example: 10,000W generator.
2. Voltage. This is the electric potential; usually 220V, or in the case of big generators, 240V.

This is all you need to determine how many amps does your generator draw. We are going to look into how to calculate the amps by hand (using the basic electric power equation) for a 5,000W Honda generator.

Further on, you will also find the ‘Generator Amps Calculator’ and the calculated table to help you out determine the amperage of your generator.

## How To Calculate How Many Amps Does A Generator Draw?

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

P (power) = I (current) × V (voltage)

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

Watts = Amps × Volts

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

Amps = Watts ÷ Volts

If you want to calculate amps generator draws, you need to divide watts by volts. Simple, right? Let’s do 1 example before we check out the automatic ‘Generator Amps Calculator’.

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

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

Amps = 5,000W ÷ 220V = 22.73 Amps

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

To make things even easier, you can use the before-mentioned watts to amps calculator for generators:

## Generator Amps Calculator

You just insert (or use the slider) wattage and voltage, and the calculator will dynamically calculate the amps such a generator produces. You can also play around with numbers a bit to see how this calculation works:

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

Here is the promised calculated table for ampacity of 500W to 30kW generators:
