Your electrical panel is the hub of your home’s entire electrical system. When it is undersized, outdated, or from a manufacturer with known safety issues, it becomes a liability that affects everything connected to it. Flickering lights, tripped breakers, and the inability to add circuits for modern appliances and EV chargers are all signs that your panel needs to be replaced. At Wise Choice Remodeling (CSLB #1104186), we replace outdated and undersized electrical panels with properly rated units sized for your current needs and future additions, fully permitted and inspected to current California electrical code.
Signs You Need an Electrical Panel Upgrade
Here are the most common indicators that your electrical panel needs to be replaced:
- Breakers that trip frequently under normal household loads
- Panel is a Federal Pacific, Zinsco, or fuse box that insurance carriers flag as unsafe
- Home was built before 1980 with an original panel that has never been replaced
- You are adding a Level 2 EV charger, hot tub, or HVAC system that exceeds current panel capacity
- Lights flicker or dim when large appliances run
- Panel shows signs of heat damage, corrosion, or burning smell near the box
- You want to add solar panels or battery backup systems that require a new panel configuration
A panel upgrade is often the first step before other electrical improvements can be made safely and to code.
Panel Upgrade Services We Provide
We handle the full range of residential electrical panel replacement needs.
Main Panel Replacement
Complete replacement of your existing main electrical panel with a properly rated unit. We size the new panel for your current load plus capacity for future additions. All work is permitted and inspected to California electrical code.
Panel Upgrade for EV Charger
Adding a Level 2 EV charger requires a dedicated 240V circuit and adequate panel capacity. We assess your existing panel and upgrade it if needed before installing the charger circuit.
Federal Pacific and Zinsco Panel Replacement
Federal Pacific Stab-Lok and Zinsco panels have documented breaker failure issues that create serious fire and safety risks. We replace these panels as a priority safety upgrade.
Subpanel Installation
For additions, detached garages, ADUs, and workshop spaces that need their own circuit distribution, we install subpanels fed from the main panel to provide dedicated electrical service to the new space.
Panel Safety Risk Assessment
Understanding your panel’s risk level helps prioritize the urgency of replacement.
| Panel Issue | Risk Level | Recommended Action |
|---|---|---|
| Federal Pacific Stab-Lok | High — documented breaker failure | Replace immediately |
| Zinsco panel | High — documented breaker failure | Replace immediately |
| Fuse box | High — no overcurrent protection | Replace immediately |
| Undersized panel (100A or less) | Moderate — cannot meet modern demand | Upgrade when adding circuits |
| Outdated but functional panel | Low to moderate | Assess and plan replacement |
Our Electrical Panel Upgrade Process
Panel Assessment
We assess your existing panel, identify the make and model, evaluate the current load, and confirm the appropriate replacement size for your home’s needs.
Permit Application
Panel replacement requires a permit in California. We submit the application and handle any plan check corrections.
Panel Replacement
Our licensed electricians disconnect the old panel, install the new panel, transfer all circuits, and label every breaker clearly.

How Long Does an Electrical Panel Upgrade Take?
Most panel replacements are completed in one day. The power to your home will be off for a portion of the installation day. We coordinate the timing with you to minimize inconvenience.
Electrical Panel Upgrade Cost — What to Expect
Costs vary based on the panel size, the complexity of the existing wiring configuration, and whether any additional circuit work is needed. A straightforward panel replacement is considerably less expensive than a full rewiring project.
We provide detailed written estimates at no charge based on your specific panel and home requirements.
