HOA Electrical Upgrade in San Diego: New Switchgear + 64 Subpanel Replacements

Eco Electric San Diego recently completed a major electrical modernization project for an eight-building HOA community, replacing outdated switchgear and 64 unsafe Zinsco subpanels, bringing the entire property up to current electrical and insurance standards.

This project not only made the community safer, it also protected the HOA from losing insurance coverage due to aging and hazardous electrical equipment.

Why This Upgrade Was Critical

Many older San Diego communities still rely on Zinsco electrical panels, which are known for overheating, failing to trip, and creating a significant fire risk. Insurance carriers are now refusing to cover buildings with these panels.

This HOA was at immediate risk of canceled insurance unless the panels were replaced across every unit.

Eco Electric San Diego was hired to manage the full replacement and ensure a smooth, safe, and fully compliant upgrade.

Scope of Work Completed

✔ Replacement of Switchgear for 8 HOA Buildings

We removed all outdated main switchgear equipment and installed new, code-compliant gear designed for long-term reliability and safe power distribution.

✔ 64 Subpanel Replacements Inside Individual Units

Each home received a brand-new electrical subpanel, fully labeled and brought up to current code standards. All old Zinsco gear was removed from the site for proper disposal.

✔ Full Coordination With All Homeowners

We handled every aspect of communication, including:

• Scheduling individually with each resident

• Posting required 72-hour power-shutdown notices

• Providing daily updates and answering homeowner questions

• Minimizing downtime for each unit

No resident experienced more than a short afternoon of downtime while the new subpanels and main switchgear were energized.

✔ SDG&E Communication and Power Shutdown Management

We coordinated directly with SDG&E to handle all shutdowns, inspections, and re-energizing procedures. This ensured a safe transition and compliance with utility requirements.

✔ Safe Removal & Disposal of All Old Gear

Every outdated, unsafe Zinsco and legacy switchgear component was removed, hauled off-site, and properly disposed of.

Minimal Impact, Maximum Safety

One of the biggest concerns for the HOA was avoiding extended outages. Our team created a highly organized schedule that allowed us to:

• Complete each building’s switchgear upgrade in a single afternoon

• Replace subpanels inside each unit the same day

• Keep all essential services powered whenever possible

We worked efficiently to keep disruptions low while delivering a full modernization across all eight buildings.

The Results

With all new switchgear and 64 brand-new sub panels, this HOA is now:

• Fully compliant with current electrical code

• Protected from insurance cancellation

• Safer from overloads, arcing, and panel failures

• Better prepared for future electrical loads

Eco Electric San Diego once again delivered a high-quality, well-coordinated project with the homeowners convenience and safety as top priorities.

Why This Project Was Urgent

Eco Electric San Diego was recently contracted to complete a 400-amp, 9-meter service replacement and full sub-panel upgrades at a multi-unit apartment property in Pacific Beach, San Diego. The existing electrical system relied on original Zinsco switchgear and sub-panels  equipment that is widely documented as dangerous, outdated, and a major liability risk.

The urgency? The property’s insurance carrier issued a cancellation notice, stating coverage would be dropped unless the Zinsco meters and sub-panels were replaced. Without immediate action, the landlord faced both loss of insurance coverage and dramatically increased premiums from alternative carriers.

The Risks of Zinsco Electrical Gear

Zinsco electrical panels, once common in Southern California apartments and condos, are now known to be unsafe:

• Breaker Failures – breakers often fail to trip, allowing overheating and fire hazards.

• Overheating Bus Bars – aluminum conductors fuse, causing arcing and electrical failure.

• Insurance Problems – many carriers refuse to insure properties with Zinsco gear.

• Code Non-Compliance – no modern grounding or bonding, failing NEC standards.

For landlords and HOAs, these panels create a direct financial and safety threat: either replace the equipment or face insurance cancellation and skyrocketing premiums.

Our Solution in Pacific Beach: 400A Service & Sub-Panel Upgrades

Eco Electric San Diego engineered and installed a complete 400A service upgrade with a 9-meter stack, while also replacing each sub-panel inside every apartment unit.

Key project steps included:

• Demolition & Removal of the old Zinsco meter bank and tenant sub-panels.

• Installation of New 400A Service Gear with copper bussing and modern breakers.

• Nine New Meters installed to SDG&E specifications for reliable power distribution.

• New Sub-Panels in Each Unit — giving every tenant safe, code-compliant power.

• Grounding & Bonding Upgrades to meet today’s California electrical code.

• Coordination with SDG&E for shutdown, inspection, and reconnection.

• Tenant Communication to minimize downtime during sub-panel changeouts.

Most importantly, Eco Electric San Diego worked closely with the landlord, building owner, and insurance company to ensure there was no lapse in coverage throughout the process. By coordinating schedules and compliance documentation, the property maintained continuous insurance protection.

Why Landlords and HOAs Need to Act Now

If your property still has Zinsco, Federal Pacific, or other outdated gear, your insurance may already be at risk. We are seeing more and more:

• Insurance cancellations tied to Zinsco or FPE electrical equipment.

• Premium hikes of 30–100% for properties with outdated panels.

• HOA liability issues when boards delay necessary electrical upgrades.

Replacing both the main service gear and in-unit sub-panels not only satisfies insurance requirements but also improves tenant safety and property value.

Project Showcase:

What Is a Zinsco Panel and Why Is It Dangerous?

Zinsco electrical panels were commonly installed in homes from the 1950s through the 1980s. While they were considered innovative at the time, modern research and field data have revealed serious safety issues.

Major Problems With Zinsco Panels:

• Circuit breakers fail to trip when overloaded

• Electricity may still flow even when breakers are switched off

• Overheating and arcing are common inside the panel

• High risk of electrical fires

• Difficult to find replacement parts

• Do not meet current electrical safety codes

🔥 Real Fire Hazards: Zinsco Panel Failure in Action

This image shows a real example of what happens when a Zinsco panel fails. These issues aren’t just theoretical — we see damage like this regularly in homes that haven’t been upgraded.

🏠 How This Affects Your Home (and Your Insurance)

If your home still has a Zinsco panel, you could be at risk in more ways than one:

• Fire Risk: Breakers may not shut off during faults, leading to overheating and fire.

• Electrical Code Violations: These panels are no longer approved under current codes.

• Insurance Red Flags: Many insurers may deny or cancel policies for homes with Zinsco panels.

✅ What a Safe Electrical Panel Looks Like

A modern panel is designed with up-to-date circuit breakers that reliably trip during faults, reduce fire risk, and ensure your home meets all local electrical codes. Upgrading offers:

• Better safety

• Easier maintenance

• Increased property value

• Peace of mind

🔍 How to Tell If You Have a Zinsco Panel

Not sure if your panel is a Zinsco? Here are a few signs:

• The name “Zinsco” or “Zinsco-Sylvania” on the panel or breakers

• Brightly colored breaker switches (often red, green, or blue)

• Breakers that are difficult to remove or don’t snap in like modern ones
