Electrical Service Upgrade — Frequently Asked Questions

What's the difference between a panel upgrade and a service upgrade?

A panel upgrade replaces just the electrical panel. A service upgrade replaces everything from the utility connection point inward — the weatherhead, service entrance cable, meter base, main panel, and grounding system. Service upgrades are needed when the wiring from the street to your home is undersized for your power needs, or when upgrading from 100A to 200A+ where the existing service entrance cable can't handle the load.

How long does a service upgrade take, and will I be without power?

A complete service upgrade typically takes 1–2 days. The actual power outage is usually 4–8 hours on the day Eversource disconnects the old service. We schedule this in advance so you can plan around it. Most customers use this window to run errands or spend the day out.

Do I need Eversource approval for a service upgrade?

Yes, but we handle all of it. We submit the application, schedule the disconnect and reconnect, and coordinate the inspection. You don't need to deal with the utility company directly — that's part of our service.
