Electrical Output Capacity for Home Generators
Background: Jean, a Homeowner from Grass Valley, CA

Question: Hi Dave – Could you change a 30 amp outlet to be a 50 amp on a diesel generator?
We could bring it to you.
This is for my husband George.

Dave’s Reply:
Thanks for your electrical question Jean.
Understanding Generator KW Output Capacity

• Because the generator came with a 30 amp outlet it most likely is limited to 30 amp output otherwise there would be a 50 amp outlet already installed.
• Changing to a larger outlet would not enlarge the capacity of the generator KW output.
• It would be best to check the specifications and the KW capacity of the generator to really know for sure.
• The total connected load that will be placed on a generator should be known before selecting a generator.
• Special equipment loads must also be identified to make sure the generator capacity will support them.
• Motor loads such as well pumps must be factored in when selecting the home generator.
