Electrical Panel Upgrade
Your electrical panel is the heart of your home's electrical system. It distributes power to every circuit, protects your wiring with breakers, and determines how much total electrical capacity your home can handle. If your home has an outdated fuse box, a 100-amp panel, or a panel that can no longer keep up with your electrical demands, upgrading to a modern 200-amp panel is one of the most important investments you can make in your home's safety and functionality.
Why Upgrade Your Electrical Panel?
Most homes built before 1980 have 100-amp or even 60-amp electrical service — designed for an era before central air conditioning, home offices, EV chargers, and modern kitchen appliances. Today, a 200-amp panel is the standard for single-family homes in California. Upgrading increases your home's electrical capacity, reduces the risk of overloaded circuits and electrical fires, brings your system up to current California Electrical Code, and is often required before you can install an EV charger, add a room, or upgrade your HVAC system.
What Does a Panel Upgrade Involve?
A full panel upgrade typically includes: removing the old panel or fuse box; installing a new 200-amp panel with modern circuit breakers; upgrading the service entrance cable from the utility meter to the panel; coordinating with your utility provider (LADWP, SCE, or municipal utility) for the service drop if needed; pulling all required permits from your local building department; and scheduling the final inspection. The work usually takes one full day for a straightforward upgrade, though homes requiring additional service entrance work may take longer.
Panel Upgrade Cost Factors in California
A 200-amp panel upgrade in California typically costs between $2,500 and $5,000. The price depends on several factors: the condition and location of your existing panel; whether the service entrance cable and meter base also need replacement; your utility provider's requirements (LADWP, SCE, GWP, BWP, and PWP each have different specifications); permit fees, which vary by city; and whether additional circuits need to be added during the upgrade. We provide a written, itemized estimate before starting any work.
Recalled and Dangerous Panel Brands
Several electrical panel brands have documented safety issues. Federal Pacific Electric (FPE) Stab-Lok panels have been shown in independent testing to fail to trip under overload conditions. Zinsco panels are known for breakers that fuse to the bus bar, preventing them from tripping during a fault. Pushmatic panels use a push-button design that can become unreliable with age. If your home has any of these panel types, replacement is strongly recommended regardless of your current electrical capacity needs. We can identify your panel brand during a free evaluation.
Coordinating with Your Utility Provider
A panel upgrade often requires coordination with your local utility company. In Southern California, that means working with LADWP, Southern California Edison (SCE), or one of several municipal utilities. Each provider has specific requirements for the service drop, meter base, and interconnection. We have experience working with every major California utility and handle all coordination, applications, and scheduling on your behalf. This is one of the steps that most often delays a panel upgrade when homeowners try to manage it themselves.
Warning Signs to Watch For
- Breakers trip frequently under normal use
- You still have a fuse box instead of a breaker panel
- Your panel is rated at 100 amps or less
- You need to install an EV charger, hot tub, or major appliance
- Your panel is a recalled brand (Federal Pacific, Zinsco, or Pushmatic)
- Visible rust, corrosion, or burn marks on your panel
- You hear buzzing or crackling from the panel
- You're planning a home addition or major renovation
What Affects the Cost
- Current panel amperage and condition (100-amp, fuse box, or damaged panel)
- Whether the service entrance cable and meter base need replacement
- Utility provider requirements and application fees
- Local permit fees, which vary by city
- Number of additional circuits to be added during the upgrade
- Panel location and accessibility
Frequently Asked Questions
How long does a panel upgrade take?
A standard 200-amp panel upgrade typically takes 6 to 10 hours to complete. Your power will be off during the replacement, usually for 4 to 8 hours. We coordinate with your utility company in advance so the service disconnection and reconnection happen on the same day whenever possible.
Do I need a permit for a panel upgrade in California?
Yes. Panel upgrades require an electrical permit in every California jurisdiction. The permit ensures the work is inspected and meets current California Electrical Code. We handle the entire permit process — application, fees, and scheduling the inspection — as part of every panel upgrade project.
Is my Federal Pacific or Zinsco panel dangerous?
Federal Pacific Electric (FPE) Stab-Lok panels and Zinsco panels have well-documented safety concerns. Independent testing has shown that some FPE breakers fail to trip during overload conditions, which can lead to electrical fires. If your home has one of these panels, we recommend replacing it regardless of whether you need additional capacity. We can inspect your panel and advise you on the urgency of replacement.
Will a panel upgrade increase my home value?
A 200-amp panel upgrade is one of the improvements that home inspectors and buyers specifically look for. Homes with modern panels are easier to insure, qualify for more financing options, and avoid the negotiation issues that arise when a buyer's inspection flags an outdated or recalled panel. While the exact value increase varies, the upgrade typically pays for itself in avoided insurance surcharges and improved marketability.
Can I add circuits during a panel upgrade?
Yes, and a panel upgrade is the ideal time to add circuits. Since the panel is already open and the permit covers the work, adding dedicated circuits for a kitchen, bathroom, home office, or EV charger during the upgrade is more cost-effective than doing it as a separate project later.
