Why Florissant Homes Need Panel Upgrades

The majority of Florissant homes were built between 1950 and 1975, when 100A service was standard and today's electrical loads — EV chargers, central AC, electric ranges, home offices — didn't exist. A 200A panel upgrade gives your Florissant home the capacity to handle modern demands safely. Florissant has one of the highest concentrations of post-war homes in North St. Louis County — many with original Federal Pacific panels and aluminum branch wiring.
