Scope of Work

When to Upgrade

If your facility trips breakers regularly, runs out of circuit space, or needs to add major equipment, a panel upgrade solves the root cause. Common reasons: reached max capacity, adding HVAC/kitchen/manufacturing loads, space conversion, insurance or code findings, replacing obsolete Federal Pacific or Zinsco panels, or preparing for EV chargers and solar.

  • Main service upgrades (200A to 400A, 400A to 800A)
  • Sub-panel additions and distribution expansions
  • Panel and switchgear replacements
  • Bus duct and feeder upgrades
  • Utility coordination and service entrance work
  • Infrared thermal scanning
  • Breaker testing and torque inspections
  • Arc flash studies and labeling
