Why Fenton Homes Need Panel Upgrades

Fenton homes range from 1960s-era ranches to newer construction near Gravois Bluffs, 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 Fenton home the capacity to handle modern demands safely. Fenton's mix of older residential neighborhoods and growing commercial corridor means we handle both residential and commercial electrical work here regularly.
