Utility rules and programs for Manchester
Eversource serves homes in Manchester.
| Utility | Type | Generator rules |
|---|---|---|
| Public Service Co of NH | investor-owned | A generator transfer switch or interlock is electrical work for a licensed New Hampshire electrician (the Electricians’ Board licenses electrical installations); ask your town about a permit and inspection. |

What to plan for in Manchester
- Ice storms (very high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Winter weather (relatively high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
