Size of Generator Transfer Switch

Choosing the right size generator transfer switch is crucial to ensure your home is powered during a power outage.

Determining the Right Size

The size of the transfer switch you need will depend on the size of your generator and the electrical load of your home.

It’s important to determine the right size to avoid overloading the generator, which can cause damage or even a fire.

Factors to Consider

When determining the right size transfer switch, consider the following factors.

  1. Size of your generator: The size of your generator will determine the maximum power output it can provide, which will in turn determine the size of the transfer switch you need.
  2. The electrical load of your home: The electrical load of your home refers to the total amount of power your home uses. This can be determined by adding up the wattage of all the appliances and electrical devices in your home that you want to power during an outage.

Small-Sized Transfer Switch


If you have a portable generator (up to 5,000 watts) and only need to power a few essential circuits in your home, a small-sized transfer switch may be sufficient. This type of switch typically ranges from 6 to 10 circuits and can cost between $200 to $500.


Medium-Sized Transfer Switch


If you have a medium-sized generator (5,000 to 10,000 watts) and want to power more circuits in your home, a medium-sized transfer switch may be necessary. This type of switch typically ranges from 10 to 16 circuits and can cost between $500 to $1,000.


Large-Sized Transfer Switch


If you have a standby generator (10,000 watts or more) and want to power most or all circuits in your home, a large-sized transfer switch may be required. This type of switch typically ranges from 16 to 24 circuits and can cost between $1,000 to $2,500.
