Upgrading your electrical panel is a critical step in ensuring the safety, efficiency, and capacity of your home’s electrical system.

Why Your San Leon Home May Need an Electrical Panel Upgrade
Older homes in San Leon often have panels that were designed for much lower electrical loads than today’s standard appliances and electronics require. Common signs indicating you might need an electrical panel upgrade in San Leon include:
- Frequent Circuit Breaker Trips: Tripping breakers suggest your panel is overloaded or the breakers are outdated and unable to handle current electrical loads.
- Flickering or Dimming Lights: Voltage drops from an insufficient panel capacity can cause visible flickering or dimming in lighting fixtures.
- Outdated Panel Components: Panels with fuses or obsolete breakers, or those from manufacturers with known recall histories, need replacement for safety reasons.
- Adding High-Power Appliances: If you’re installing EV charging stations, generators, or high-demand HVAC systems, your existing panel may lack the capacity or proper integration.
- Electrical Shocks or Warm Outlets: These serious safety concerns often relate to inadequate panel grounding or worn-out components.
- Lack of Space for New Circuits: When your current panel is full, adding circuits for new devices or rooms becomes unsafe and difficult.
San Leon homes are frequently exposed to humidity, which can corrode electrical components, increasing the risk of failure and fire hazards. A panel upgrade addresses these issues with modern, corrosion-resistant materials and improved surge protection.
Load Assessment and Panel Sizing for San Leon Homes
Before a panel upgrade, a comprehensive load assessment is conducted. This assessment ensures your new panel matches current and projected energy demands. The process includes:
- Reviewing your home’s existing electrical appliances, HVAC systems, lighting, and future plans for additions like EV chargers or standby generators.
- Calculating total electrical load requirements based on National Electrical Code (NEC) guidelines and local San Leon electrical codes.
- Recommending an appropriate panel size, typically between 100 and 200 amps for residential upgrades, though larger panels are available when needed.
Correct panel sizing avoids underpowered systems that cause frequent trips or overheating, as well as overspending on unnecessarily large panels.

Safety Improvements and Surge Protection Options
An electrical panel upgrade is an opportunity to boost your home’s safety significantly. Key safety features we recommend for San Leon homes include:
- Surge Protection Devices (SPDs): These devices protect your home’s electronics and appliances from voltage spikes caused by lightning, utility issues, or switching surges prevalent in coastal areas like San Leon.
- Arc Fault Circuit Interrupter Breakers: AFCI breakers reduce the risk of electrical fires caused by arcing faults.
- Ground Fault Circuit Interrupter Breakers: GFCI breakers are essential in damp or wet areas to prevent shocks and electrocutions.
- Proper Panel Grounding and Bonding: Ensuring your panel is properly grounded protects against shock hazards and electrical noise.
Integration with Added Loads Like EV Chargers and Generators
San Leon residents are increasingly adopting clean technologies such as Electric Vehicle (EV) charging stations and whole-house generators to improve convenience and resiliency. A modern panel upgrade can seamlessly incorporate these:
- EV Charger Integration: Our electricians install dedicated circuits with appropriate amperage to support Level 2 EV chargers, avoiding overloads and maintaining electrical integrity.
- Generator Interlock Kits or Transfer Switches: When adding a generator, integration with your electrical panel is vital to prevent back feeding and ensure safe power switching during outages. We provide expert installation and connection tailored to your generator model and panel type.

Factors influencing the cost include:
- Panel amperage and brand selection.
