What Is an Electrical Panel Upgrade?

An electrical panel upgrade replaces your old, unsafe, or undersized breaker box with a new, modern, properly sized service panel.

Adding new circuits

Supporting modern appliances

Installing an EV charger

Powering HVAC systems

Whole house rewiring

Preventing electrical fires

A properly installed electrical panel ensures your entire system can safely deliver the power your home needs — without overheating, tripping, or creating fire hazards.

Signs You Need an Electrical Panel Upgrade

Most homeowners aren't sure when their panel needs to be replaced. But your electrical system sends clear signs:

1

Breakers trip frequently

This is the #1 symptom of an overloaded or failing panel.

2

Lights flicker or dim when appliances run

Often caused by inadequate power capacity.

3

Your home still has a fuse box

Fuse boxes became outdated decades ago — they cannot support modern electrical loads.

4

Burning smells near panel or outlets

This is a serious hazard and requires immediate evaluation.

5

Warm or buzzing electrical panel

Panels should never make noise or feel warm to the touch.

6

You have two-prong, ungrounded outlets

This indicates wiring and panel grounding issues.

7

Adding high-demand appliances

EV chargers, hot tubs, HVAC systems, kitchen remodels, laundry room upgrades.

8

Old or dangerous panel brands

Federal Pacific (FPE), Zinsco/Sylvania, Challenger, Pushmatic, Bulldog.

9

Home is 40+ years old

Panels have a lifespan of 25–40 years.

If you notice any of these issues, an electrical panel replacement is the safest solution.

Why Your Home May Require a Panel Upgrade During a House Rewire

If you're searching for "rewire my home," "whole house rewire electrician," or "home wiring replacement," then a panel upgrade is often part of the project.

A panel upgrade is typically required when:

  • The existing panel is undersized
  • The panel is unsafe
  • There are not enough circuits
  • The grounding system is outdated
  • You're switching from two-prong to three-prong outlets
  • You're adding new circuits (kitchen, laundry, HVAC)
  • The panel cannot support arc-fault or GFCI breakers
  • The home requires additional capacity

Rewiring with an outdated panel is unsafe and will not pass inspection. We evaluate your panel and tell you whether an upgrade is necessary.

Electrical Panel Upgrades for EV Chargers

EV chargers (Level 2) require 40A–60A breakers, 240V dedicated circuits, upgraded grounding, and sufficient panel capacity.

If your panel is undersized, we upgrade it before EV charger installation.
