Reliable Electrical Panel & Capacity Upgrades

Modern St. Louis homes rely on significantly more electrical power than the systems designed several decades ago were originally built to handle.

Panel Replacement FAQs

  • Why do home insurance companies require replacing Federal Pacific or Zinsco panels?

    Federal Pacific Electric (FPE) and Zinsco panels have documented design flaws where breakers frequently fail to trip during overloads or short circuits. Insurance carriers often require replacing these hazardous panels with modern equipment before issuing or renewing home coverage.

  • What is the difference between a 100-amp and a 200-amp service panel?

    A 100-amp panel provides basic electrical current suitable for smaller properties with minimal electronics. A 200-amp main panel doubles total electrical capacity, providing the necessary amperage and breaker space to safely power high-draw HVAC units, kitchen remodels, EV chargers, and hot tubs.

  • Do I need a city permit to replace an electrical panel in St. Louis?

    Yes, replacing or upgrading a main electrical panel in St. Louis City or St. Louis County requires a municipal electrical permit and a final inspection to verify code compliance and safety standards.

  • How long will my electricity be shut off during a panel replacement?

    Power is typically shut off for 4 to 8 hours on the day of installation while our technicians replace the panel box, service entrance lines, and ground connections safely.

  • Will an electrical panel replacement allow me to install an EV charger?

    Yes, upgrading to a 200-amp service panel provides the physical breaker space and electrical load capacity required to run a dedicated 240-volt Level 2 EV charging circuit.
