Can a Circuit Breaker be Upgraded?

Whether a commercial circuit breaker can be upgraded depends on several critical factors, including your building’s current electrical capacity, compliance with the California Electrical Code (Title 24), and the physical condition of your existing equipment. In coastal areas like Marina del Rey, salt air causes rapid corrosion of bus bars, wiring, and panel components, making a professional feasibility assessment essential to determine if an upgrade is viable.

We offer expert Electrical Panel Upgrades and Circuit Breaker Services to help businesses transition from older, lower-amperage systems to modern 200-amp (or higher) services. Upgrading is often necessary to support modern loads such as additional lighting, AC units, and heavy machinery that frequently cause older 100-amp systems to trip or overheat.

To ensure a safe and legal installation, we follow a strict process:

• Load Calculations: We perform detailed assessments to ensure your current breaker box can handle the extra draw without risking electrical fires.
• Code Compliance: All upgrades must meet the latest National Electrical Code (NEC) standards and California-specific seismic bracing requirements for commercial equipment.
• Permitting: In Los Angeles County, all electrical upgrades require a valid permit through the Department of Public Works. Working without a permit is considered illegal and can result in insurance claim denials and legal action.
• Corrosion Resistance: For businesses near the water, we recommend using corrosion-resistant materials and enclosures to ensure long-term reliability.
