Electrical Panel Upgrades

200A and 400A service upgrades, code-compliant and permitted.

Overview

An aging or undersized panel limits everything — from EV chargers to induction ranges to HVAC. Flash Power LLC upgrades hundreds of panels each year across Maryland, DC, and Virginia, including utility coordination and same-day cutovers.

What's included

  • 100A → 200A and 200A → 400A upgrades
  • Federal Pacific, Zinsco, and Challenger panel replacement
  • Square D, Eaton, and Siemens panel installs
  • Meter base, mast, and service entrance replacement
  • Whole-home surge protection included
  • Utility coordination with Pepco, BGE, Dominion, and Washington Gas

Our process

  1. 1. Load calculation
    We perform a NEC load calc and recommend the right service size.
  2. 2. Permit & utility coordination
    We pull the permit and schedule the utility disconnect/reconnect.
  3. 3. Single-day install
    Most panel upgrades are completed in one day with the home re-energized by evening.
  4. 4. Inspection & closeout
    We meet the inspector, close the permit, and email you the closed permit copy.
