Signs You Need an Upgrade
Common Electrical Panel Problems
These are the most frequent issues we find in homes and businesses across Los Angeles County that indicate the panel needs attention.
Undersized Panel
A 100-amp panel can't handle modern loads — EV chargers, HVAC, and appliances demand more capacity than older services provide.
Outdated or Unsafe Equipment
Federal Pacific and Zinsco panels are known fire hazards. Fuse boxes should be replaced with modern breaker panels for safety and code compliance.
Breakers That Keep Tripping
Frequent trips indicate overloaded circuits, failing breakers, or faulty wiring — all of which need to be diagnosed and resolved.
No Room to Add Circuits
If every slot in your panel is full, you're out of options until you upgrade. New EV chargers, hot tubs, and additions all need dedicated circuits.
Flickering or Dimming Lights
Voltage fluctuations caused by an overloaded or failing panel can damage sensitive electronics and signal larger wiring issues.
Home Sale or Renovation
Inspectors routinely flag outdated panels. Upgrading before listing removes a common negotiation point and speeds up closing.
What We Do
What's Included in a Panel Upgrade
Every panel upgrade starts with a proper load calculation and an inspection of your existing service. We size the new panel correctly for your current and anticipated loads — not just the minimum code allows.
Every panel upgrade includes:
- Load calculation — not guesswork
- Full panel replacement (100A → 200A or higher)
- New breakers + proper circuit labeling
- Federal Pacific & Zinsco replacements
- GFCI & AFCI breakers where required by code
- Permit + inspection handled for you
- Cleanup included — we leave it clean
Code & Permit Work
Permitted, Inspected & Code-Compliant
Panel upgrades in Los Angeles County require a permit from the Department of Building and Safety. We handle the permit application, schedule the inspection, and complete all work to current NEC and California Title 24 standards.
Unpermitted panel work can create problems during a home sale, insurance claims, and future inspections. Every upgrade we complete is done properly — no shortcuts.
We handle permits and inspections so you don't have to deal with the city.
