What Is Considered an Electrical Service Upgrade for Homeowners?

An electrical service upgrade is the replacement and right‑sizing of your home’s incoming electrical equipment so it can safely handle modern loads and meet current code. Most homeowners pursue this when adding high‑demand equipment (like EV chargers or heat pumps) or when an older panel shows limits such as frequent trips or flickering lights. An upgrade typically focuses on the main service equipment and grounding system, includes permit and inspection steps, and is designed for both today’s needs and your next planned appliance. We regularly complete these projects for homeowners in the Norfolk area.

Typical components included:

• New main electrical panel and main disconnect sized for current and future loads
• Upgraded meter socket, service mast or service entrance wiring, and grounding/bonding
• Added subpanels or dedicated circuits for EV chargers, heat pumps, or generators
• Whole-home surge protection with permit and inspection coordination

If you notice burning smells or hot breakers, turn off the affected circuit and contact a licensed electrician immediately.
