How to determine what size generator you need

Choosing the right size industrial generator for your worksite is not only important for making sure there is enough energy, but to also help keep machines and employees safe. Using the wrong size generator can lead to power surges, damaged equipment and even start a fire.

That’s why you should always consult a certified electrician or a Carter Machinery power equipment rental specialist. For our specialist to help you select the generator that is best for your upcoming project or event, you will need to know the following information about your energy needs: 

  1. Make a list of items the generator will be powering along with the running wattage of each one. In some cases, you may need to convert amperes to watts. Here’s how you can make that conversion:

    For resistive load: Wattage = amperes x volts
    For reactive load: Wattage = (amperes x volts) x load factor

  2. Let our experts know if all these items will be running at the same time, or if they will be operating on a rotating schedule. This information will determine the maximum amount of usage and ensure that the generator is able to perform at all times while also avoiding failures and saving on costs.
  3. Contact a certified power equipment dealer and determine if it will be best for you to rent or buy an industrial generator. A variety of factors will determine which option is best for you and a certified dealer can help you make that decision.
