Main Panel Upgrades in San Diego

Warning Signs

When Do You Need a Panel Upgrade?

A panel upgrade is usually the right move if you're dealing with:

1. Breakers tripping frequently or lights dimming/flickering
2. A panel that's 100A but you need more capacity (EV charger, HVAC, remodel, additions)
3. Warm/burning smell near the panel or visible discoloration
4. Buzzing/crackling sounds from the panel
5. Old or discontinued equipment (Zinsco, Federal Pacific, etc.)
6. Switching major loads (electric appliances, heat pumps, shop equipment, etc.)
7. Need to bring the system up to current code for permits/insurance

Residential

Residential Main Panel Upgrades

Modern homes pull more power than ever—EV chargers, induction cooking, heat pumps, spas, solar + battery systems, and full remodels all add load. If your panel is maxed out, an upgrade prevents bottlenecks and reduces the chance of unsafe workarounds.

1. 100A → 200A service upgrades
2. Panel replacements (same amperage, new equipment)
3. Adding circuits for kitchen remodels, ADUs, laundry, and HVAC
4. EV charger-ready panel capacity planning
5. Subpanel installs to expand circuit space

Commercial

Commercial & Light-Industrial Panel Upgrades

For businesses, power reliability matters. A panel that's undersized or deteriorating can cause downtime, equipment issues, and safety hazards. We help commercial properties increase capacity and modernize distribution safely—while keeping disruption as low as possible.

1. Main panel replacements and service upgrades
2. Adding circuits for tenant improvements and build-outs
3. Dedicated circuits for HVAC, refrigeration, office equipment, and machinery
4. Load assessments for expansions and new equipment
5. Subpanels and distribution improvements for better circuit management
6. Electrical safety corrections and code upgrades

Process

Our Panel Upgrade Process

1. 1. Site visit + evaluation – We check your existing panel, feeders, grounding/bonding, and capacity.
2. 2. Load planning – We confirm what you need now and what you might add later.
3. 3. Permits + coordination – We handle permitting and coordinate with the utility when a service disconnect is needed.
4. 4. Installation – Old equipment out, new panel in, circuits landed neatly, labeling done right.
5. 5. Testing + walkthrough – We verify proper operation, torque/termination, and confirm everything is functioning correctly.

Code Compliance

Safety & Code Compliance

Panel work isn't the place for shortcuts. We follow current electrical code requirements and best practices—especially around:

1. Proper grounding and bonding
2. Correct wire sizing and breaker sizing
3. Clean, secure terminations and torque specs
4. Accurate panel schedules (labels that actually make sense)
5. Load balancing and circuit organization
