EV Charger Install · Franklin County & St. Louis, MO
Buying an EV — or already drove one home and need a real charger? CAS Electric installs Level 2 (240V) EV chargers across Franklin County and the Greater St. Louis area. We handle the load calc, the permit, the panel work, and the install — for Tesla Wall Connectors, ChargePoint, Wallbox, Grizzl-E, JuiceBox, and any other UL-listed unit you bring us.
Most Level 2 EV charger installs in the St. Louis area run $800–$2,200 depending on distance to the panel, conduit routing, and whether a sub-panel is needed. Service upgrades (if required) are quoted separately.
We check your panel capacity, measure the run to your parking spot, and confirm whether a sub-panel or service upgrade is needed.
We pull the electrical permit. If you haven't bought a charger yet, we'll recommend a unit matched to your car and amperage.
Dedicated 240V circuit, hardwire or NEMA 14-50 outlet, mounted charger, clean conduit, and a labeled breaker.
Local inspector signs off, we plug in and confirm charging speed with you before leaving.
Most installs in Franklin County and the St. Louis area run $800–$2,200. The variables are how far the charger sits from your panel, whether conduit has to go through finished walls, and whether your existing panel has capacity for a 40–60 amp circuit. We give a flat quote after looking at the panel.
Yes. Every Franklin County and St. Louis-area jurisdiction requires a permit and inspection for a hardwired Level 2 charger or a dedicated 240V circuit. We pull the permit and coordinate the inspection as part of the install.
Most 200-amp panels can — but a 100-amp panel or an older home with electric heat, an A/C, and an electric range may not. We do a load calculation on-site and tell you honestly whether you need a sub-panel, a load-management charger, or a full service upgrade.
Any UL-listed Level 2 unit — Tesla Wall Connector (including non-Tesla EVs), ChargePoint Home Flex, Wallbox Pulsar Plus, Grizzl-E, JuiceBox, Emporia, and the chargers Ford, GM, and Rivian ship with new vehicles. If you haven't bought one yet, we'll recommend a unit sized to your car.
Hardwired is required above 40 amps and is generally cleaner and more reliable. A NEMA 14-50 outlet is fine for 32A charging and lets you unplug the charger to take it with you. We'll recommend the right setup based on your charger and how much amperage your car can actually pull.
