Signs You Need a Panel Upgrade
- Frequent tripped breakers, especially when running multiple appliances
- Panel is a Federal Pacific "Stab-Lok" or Zinsco brand (serious safety concerns — upgrade strongly recommended)
- Adding an EV charger, hot tub, or major addition that exceeds panel capacity
- Fuse box (not circuit breakers) — these are from pre-1960s and should be upgraded
- Aluminum wiring throughout the home (requires specific remediation)
The Upgrade Process
A panel upgrade requires: licensed electrician to perform work, building permit (required in virtually all jurisdictions), utility coordination to cut and restore power from the street, and final inspection by building department. Plan for 1 day of work for the electrician plus a utility outage window. Don't skip permits — unpermitted electrical work creates insurance and resale problems.

Frequently Asked Questions
Do I need a permit to upgrade my electrical panel?
Yes, in virtually all US jurisdictions. Electrical panel work is inspected by the building department to verify code compliance. Unpermitted panel work creates problems when selling a home (required to disclose unpermitted work), invalidates homeowner's insurance in some policies, and creates safety risks if improperly installed.
Can I get a tax credit for upgrading my electrical panel?
The Inflation Reduction Act created a 30% tax credit (up to $600) for electrical panel upgrades made for the purpose of installing qualifying energy equipment. This applies when the panel upgrade is done in connection with installing a heat pump, EV charger, solar, or other eligible equipment. Consult a tax professional for current rules.
