Does My Generator Need to Be Grounded With a Grounding Rod?

In most cases, portable generators used for backup home power do not require a separate grounding rod when connected through a transfer switch, interlock kit, or GenerLink system.

This is because the generator is typically grounded through the home’s electrical system.

Grounding Requirements May Vary

Grounding requirements can vary depending on:

• Local electrical codes

• How the generator is connected to the home

• The type of transfer equipment being used

Because of these variables, grounding requirements may differ by location.

Professional Recommendation

⚠ We recommend consulting a licensed electrician to verify the grounding requirements for your specific installation and to ensure compliance with local electrical codes.
