Electrical Panel Upgrade for Wilmington Homeowners
Wilmington is one of the older residential communities in the South Bay, and many homes here were built in the 1950s, 1960s, and 1970s with electrical systems that simply were not designed for modern demand. Adding a home office, a heat pump, a washer and dryer, or an EV charger can push an aging 100-amp panel past its limits and create real safety risks.
Ziello Electric provides electrical panel upgrade services throughout Wilmington and neighboring communities including Harbor City, San Pedro, and Lomita. Our licensed electricians handle everything from permit applications to the final city inspection, so you get a code-compliant upgrade without the hassle.
What’s Included in Our Electrical Panel Upgrade
When Ziello Electric upgrades your panel, you get a complete installation, not just a box swap. We take care of every component involved in bringing your home’s electrical system up to current California standards.
New Panel and Circuit Breaker Installation
We install a new load center sized to meet your current and future electrical needs, typically a 200-amp panel for most Wilmington single-family homes. All existing circuits are carefully transferred and labeled, and any damaged wiring connections are corrected during the process. You end up with a clean, organized panel that is easy to work with down the road.
Service Entrance and Grounding System Check
Many Wilmington homes have aging service entrances or inadequate grounding that can create problems even after a new panel is installed. We inspect and update the service entrance conductors, meter base, and grounding electrode system to current code. This step is especially important in coastal areas where salt air and moisture can accelerate corrosion in electrical components.
Permit Coordination and City Inspection
Electrical panel upgrades in Wilmington require a permit from the City of Los Angeles Department of Building and Safety. Ziello Electric pulls the permit on your behalf and schedules the required LADBS inspection. Once the inspector signs off, you have documentation that the work was done to code, which matters when selling your home or filing an insurance claim.

Signs You Need an Electrical Panel Upgrade in Your Wilmington Home
Not every electrical problem is obvious. Wilmington homeowners sometimes live with warning signs for years without realizing the panel is the root cause. Here are the most common situations that tell us a panel upgrade is overdue.
Breakers That Trip Repeatedly
If certain circuits in your home trip breakers on a regular basis, the panel may no longer be able to handle your electrical load. This is common in older Wilmington homes where one circuit is shared by too many outlets and appliances. Repeated tripping is not just inconvenient, it is a sign the system is being stressed beyond its design limits.
Older Federal Pacific or Zinsco Panels
A significant number of homes in Wilmington and nearby Harbor City still contain Federal Pacific Stab-Lok or Zinsco panels that were installed decades ago. These panels have known safety defects and may fail to trip during an overload, creating a fire risk. If your home has either brand, replacement is strongly recommended regardless of current symptoms.
Planning a Major Home Upgrade or Addition
Adding a room, upgrading to central air conditioning, or installing an EV charger installation all require dedicated circuits with adequate amperage. A 100-amp panel rarely has the capacity to support these additions safely. Upgrading your panel before or alongside a renovation prevents costly rework later and ensures your permits clear without issue.
If any of these situations sound familiar, do not wait for a bigger problem to develop. Call Ziello Electric for an assessment.
Our Electrical Panel Upgrade Process for Wilmington Homes
Schedule Your Consultation
Reach out by phone or through our website to set up a visit to your Wilmington home. We confirm a specific arrival window so you know exactly when to expect us. There is no cost for the initial estimate.
Assess Your Panel and Electrical Load
Our electrician reviews your current panel, measures your electrical load, and identifies any components that need to be addressed before or during the upgrade. For homes near the Wilmington waterfront or in older tracts near Pacific Coast Highway, we pay close attention to signs of corrosion and moisture damage in the service entrance area.
Complete the Panel Upgrade Installation
We shut off power, remove the old panel, and install your new service panel with all circuits transferred and labeled correctly. Any electrical repair items identified during the assessment are resolved at the same time. Power is restored as soon as the installation is complete and verified.
Final Inspection and Walkthrough
After installation, we schedule and pass the LADBS inspection for your Wilmington property. Once the inspector signs off, we walk you through the new panel so you know exactly what each breaker controls and how to reset it safely. You receive all permit documentation for your records.
