Choosing the right Generator

See what Briggs & Stratton generator you need to get the job done

Step 1: Determine the power required from your generator

Initially consult the owners manual or the equipments data plate to determine the power required to operate it. To calculate the Watts needed from your generator you must work out the running Watts for all the equipment you may want to run simultaneously and multiply it by the energy required to initially start up the equipment or the ‘starting coefficient’.

IF THE POWER REQUIRED FOR YOUR EQUIPMENT IS INDICATED IN AMPS, MULTIPLY BY THE VOLTS (230V) TO GIVE YOU THE WATTS. EXAMPLE: 5 AMPS X 230 = 1150 WATTS



Step 2: Determine the starting coefficient

The majority of products has a starting coefficient of 1 but below are a few examples of products that have more.

If you want to run a light bulb and a hedge trimmer your calculation would look like this:

Halogen lamp200X 1.5300
Hedge trimmer780X 21560
You will need a generator that will output at least 1860 Watts
