Commercial Electrical Panel & Service Upgrades in Los Angeles County

Commercial Electrical Panel & Service Upgrades in Los Angeles County

As your business grows, so do your power needs. Older buildings across Los Angeles County often operate on undersized or outdated electrical panels—unable to handle modern machinery, HVAC systems, or automation equipment.

At 911 Construction & Electric Inc., we specialize in commercial electrical panel upgrades and 3-phase power installations, ensuring your facility can handle today’s demands safely and efficiently.

Why Businesses Upgrade Their Panels

Commercial buildings often require:

  • Higher amperage for new equipment

  • Stable voltage for 3-phase machinery

  • Better load distribution for safety and code compliance

  • Integration with new technology like EV chargers and automation systems

An overloaded panel can cause tripped breakers, equipment damage, and even fire hazards.
