Your Trusted Electrician in Wentzville, MO
Electrical work in Wentzville, MO requires a focus on safety, dependability, and modern load expertise. At Kay-Bee Electric, we understand the unique challenges that homeowners and businesses in Wentzville face. Most Wentzville homes are post-2000 subdivisions or premium custom builds where the original 100A or 150A panel was sized before electric vehicles, heat pumps, induction ranges, and 24-kW whole-home generators became the standard. Whether you’re upgrading the panel to handle a new Tesla Wall Connector, planning a basement finish, or wiring a backup generator before the next ice storm, our licensed electricians are ready to deliver exceptional service.
Common electrical work we run for Wentzville homeowners:
- EV charger installation: Tesla Wall Connector, ChargePoint Home Flex, JuiceBox, Wallbox (Level 2 hardwired)
- 200A to 400A panel upgrades for homes with EV chargers, heat pumps, and induction ranges
- Backup generator installation (Generac, Kohler, Cummins) with ATS coordination for ice-storm continuity
- Smart switch and smart-home retrofits (Lutron Caseta, Leviton Decora Smart)
- Outdoor lighting, hot tub circuits, pool subpanels, and basement finish electrical
Your home’s electrical system is vital to your comfort and safety.

Frequently Asked Questions
Depends on your panel size and current load. A typical 200A panel in a 2,200 to 3,200 sqft Wentzville home with central AC and a gas dryer usually has room for a 50A EV circuit. A 100A panel almost always needs an upgrade before adding 50A. We run the load calculation once we're out for the job and give you the honest answer in writing before any work starts — panel capacity isn't something we quote over the phone. See our Install Electric Car Charger and Panel Replacement pages for the technical detail.
Depends on the scope. A single fixture swap is the smallest residential call we run. A whole-home panel replacement plus EV charger plus generator install is in the larger end of the residential spectrum. A full panel/service replacement or new-construction project gets every Wentzville homeowner a free on-site estimate and a written quote before any work starts — that's the only work we quote in advance. Smaller jobs aren't priced over the phone or before the visit; we price them once we're on site. If you're calling about a repair to something that's not working, that's a troubleshooting call, not an estimate — we diagnose the problem first, then quote the fix.
Same-week for most residential calls during business hours (Monday through Thursday 8AM to 4:30PM, Friday 8AM to 3:30PM). Same-day is sometimes available when we have a cancellation. For emergency residential scenarios where the power is out and the utility is fine, see our Restore Power page for what to check on your end while we schedule the visit. We don't operate a 24/7 residential dispatch line, so after-hours residential calls are scheduled for the next business day.
