I’m interested in a whole-home generator. What other equipment would I need in addtion to the generator?

There are many off-the-shelf generators available, but there’s more to the total cost of a generator.

To install a generator, you will need:

  • City/county permits for Electrical and Gas Piping.
  • A gas source such as natural gas or liquid propane, as well as the associated piping to get it to the generator.
  • A transfer switch, either automatic or manual depending on the installation and size. The transfer switch “switches” the power feeding the home from the utility to the generator and back. An automatic transfer switch does this without the need for the homeowner to do anything. A manual transfer switch requires the homeowner to turn off the utility breaker manually as well as turn on the generator breaker. The switch usually has a lockout bar to prevent both breakers from being on or closed at the same time.
  • All the electrical conduits and wiring to connect the generator to the transfer switch and to the main panel/meter base.
  • Some areas require generators to be installed on a concrete pad or on a platform above floor level. Others allow for them to be simply installed on a level gravel pad.
