Electrician Des Peres, MO

A GFCI (ground-fault circuit interrupter) protects against shock from ground faults, such as water contacting a live circuit. It's required in wet or damp locations, such as kitchens, bathrooms, garages, crawl spaces, and exterior outlets. An AFCI (arc-fault circuit interrupter) protects against electrical fires caused by arcing, which happens when damaged or loose wiring briefly sparks inside walls. The arc is often invisible until something ignites.

Under Missouri's adoption of the 2020 NEC, AFCI protection is required for all new circuits installed in bedrooms, living rooms, hallways, dining rooms, and similar finished spaces. Older Des Peres homes often have neither on circuits that predate these requirements.

If you're renovating a room, adding a circuit, or replacing a panel, those new circuits need to comply with current code. For homes built before 1999, a full evaluation by a licensed electrician is the fastest way to identify which circuits are protected and which aren't.

The most common reason is a tripped GFCI outlet upstream in the circuit. In Des Peres, homes, bathrooms, kitchens, garages, and exterior outlets must be GFCI-protected, and a tripped GFCI on a circuit cuts power to every outlet downstream. Before calling, press the "Test" and then "Reset" buttons on every GFCI outlet in the home, particularly in bathrooms and under kitchen counters, even if the dead outlet is in a different room.

Other causes include a tripped breaker (check the panel for a breaker that's moved to the center "tripped" position), a loose wire connection at the outlet itself, or a wiring fault in an older home. Homes in Des Peres with aluminum wiring are more prone to loose connections that develop intermittently, which is harder to diagnose without a proper inspection. A dead outlet that doesn't respond to a GFCI reset or breaker reset warrants a service call. Ongoing intermittent failures in older wiring should not be ignored.

St. Louis County sees an average of 50+ thunderstorm days per year, making it one of the more storm-active metro areas in Missouri. A direct lightning strike or a nearby hit on the utility line can send a voltage spike through your panel, destroying connected electronics in seconds. Individual plug-in surge strips protect one device cluster, but they don't protect hardwired appliances like your HVAC system, refrigerator, or well pump.

A whole-home surge protector installs at the main panel and intercepts voltage spikes before they reach branch circuits. According to the ESFI (Electrical Safety Foundation International), power surges are responsible for a substantial share of appliance failures each year, many of which go unattributed to surges because the damage accumulates over time rather than in one visible event.

For Des Peres homes with newer smart appliances, EV chargers, or home theater equipment, the protection is worth it. A panel-mounted surge device is a relatively low-cost addition compared to replacing the electronics it protects.
