kVa/kW Amperage Chart
The below-mentioned chart also helps in computing output amperage of the gen set according to the voltage and complete operating power. The table provided below roughly calculates the number of amps generator equipment produces during the running time and is not the right representation because of different factors that can also grow or reduce the value.

Frequently Asked Questions
What are the important things to look for when buying a 3-phase generator?
First and foremost, consider the quality of the generator. Most 3-phase generators are used to power essential and critical machines, so, when you buy a 3-phase generator, look for factors like its product name, its specifications, its size, and its power ratings. These are some of the main factors that will determine the generator’s performance.
Why should I invest in a 3-phase generator?
A 3-phase produces higher voltage, that too sustainably. It also allows for greater electrical loads as compared to a single-phase generator. The usage of 3-phase generators has become commonplace simply because of their capability of handling heavier load requirements.
How can I choose the right size for a 3-phase generator?
You must decide on the size of a 3-phase generator depending on your needs. The higher the output, the more power a 3-phase generator will provide. The higher the voltage, the costlier it will be. Remember that a 3-phase generator can also double up as a single-phase generator if need be. So, choose wisely.
Which fuel type 3-phase generator should I choose?
Usually, 3-phase generators are available in natural gas, petrol and diesel variants. Amongst the three, diesel variants are the most effective as they require lower maintenance, reducing the overall costs, reliable, stable and long-lasting. These factors make diesel 3-phase generators more popular in applications where businesses can’t afford to lose power at any given point in time.
Used or new 3-phase generator, which is a better option?
It all depends on your requirement, budget and urgency. Both used and new generators come with their own set of pros and cons. However, if you have budget and time constraints, then you must go for a used generator. For any help in buying a 3-phase used generator, you can contact Central States Diesel Generators.
