What's different about electrical panel upgrade in Saint Louis
An upgrade usually means a new meter base and service entrance as well as the panel, coordinated with Ameren Missouri. Because the City of St. Louis and St. Louis County are separate jurisdictions, check which building department covers the address before work starts. A load calculation decides the right size.
Many of these brick homes still have knob-and-tube or cloth wiring behind plaster, small services and few outlets. Renovations of older homes and vacant buildings often mean a full rewire and a new service.
Weather and the utility in Saint Louis
St. Louis summers are hot and humid, and severe thunderstorms with damaging wind are common from spring into summer. In July 2006, back-to-back storms left hundreds of thousands of Ameren customers in the region without power during a heat wave, some for more than a week. Winters bring ice and cold snaps. Ameren Missouri serves the city and handles meters, service drops and reconnection. Older brick homes often have overhead service drops in back alleys, which is where storm damage tends to show up first.
