It is true that an electric technician is the best person to inspect and calculate all you need to know about the size of a generator.

However one should avoid going to a generator dealer and buying the cheapest of them all. One should at least look at the following in order to determine the right size.

-You need to make a list of items that you will require to be run electric power from the generator.

-you also need to make a note on the starting and running wattage of the given respective items

-you also need to calculate the total power requirements in the form of KW or KVA

How do you find the starting and running wattage?

What you need to do look for is the owner’s manual or the identification plate of all the appliances you intend to use.

On the part of ampere- watt conversion, you will first note the recorded amount then convert it using this formula;

-For resistive load, wattage equals amperes multiplied by volts.

-For reactive load, wattage is equal to amperes multiplied by volts multiplied by the load factor.
