Most generator installations require electrical permits, and in some cases mechanical or building permits depending on the system size and fuel type. Homeowners in Exeter, Stratham, and Brentwood should verify permitting requirements before installation to avoid fines or delays.

Why Are Electrical Codes Important During Generator Installation?

These codes are especially important in towns like Newfields, Hampton, and Epping, where local inspectors enforce strict safety standards based on the National Electrical Code (NEC).

Does My Generator Need an Inspection After Installation?
