EV Chargers & Panel Upgrades in O'Fallon
EV charger installation is one of the most common projects we complete in O'Fallon, and it consistently sparks a broader conversation about panel capacity.
A Level 2 charger draws 30 to 50 continuous amps, a load that panels in homes built before 2005 often weren't designed to handle alongside everything else running in a modern household. Potts Electric performs load calculations before every charger installation and provides a clear recommendation on whether the existing panel can support the addition or whether an upgrade makes more sense.
Generator installations are common in O’Fallon, where past extended outages from major storm systems motivate many homeowners to plan ahead. Our team handles site assessment, fuel line coordination with your gas provider, transfer switch installation, and system testing.
Aging Electrical Systems in O'Fallon's Earlier Subdivisions
O'Fallon's earliest residential subdivisions are now old enough that the electrical infrastructure is showing its age. Homes built in the late 1980s and through the '90s often have 100-amp panels that handled the loads of that era but aren't keeping pace with today's household demands. Breakers that trip regularly, circuits that can't support added appliances, and panels that have no room for additional breakers are all signs that an upgrade is overdue.
Whole-home surge protection is a natural companion to panel upgrade projects in O'Fallon. St. Charles County sees its share of severe weather, and panel-level surge protection guards every circuit in the home against the voltage spikes that cause cumulative damage to appliances and electronics over time.

Frequently Asked Questions about Electrical Service in O'Fallon
Why do newer O'Fallon homes sometimes have electrical problems?
New construction is not immune to capacity issues, particularly in homes built in the late 1990s and early 2000s when panels were sized for the loads of that era. A household that has added an EV, a home office, and a smart HVAC system since moving in may be pushing a panel that was never designed for that combination.
Can I add a subpanel to my O'Fallon garage instead of upgrading my main panel?
In some cases, yes. A subpanel fed from the existing main panel can provide additional capacity for a specific space without requiring a complete service upgrade. Whether that approach makes sense depends on how much capacity remains in the main panel and what the subpanel needs to support.
How does O'Fallon's permitting process work for generator installations?
Generator installations in O'Fallon require a permit through the City of O'Fallon's building department, and the transfer switch work must be inspected before the system is considered complete. Coordinating that process alongside the gas line work is part of what makes proper planning important from the start.
