Fielder Electrical Services, Inc. has been wiring homes and businesses across St. Louis since 1987. As electric vehicles become part of everyday life in the area, we install dedicated EV charging circuits for homeowners, landlords, and commercial property owners throughout St. Louis City, St. Louis County, St. Charles County, and Jefferson County.
Every installation is completed by our own professional electricians under the direction of a licensed Master Electrician. We do not subcontract.
Home EV Charger Installation St. Louis, MO
Level 1 (120V): Your EV likely shipped with a Level 1 cord that plugs into a standard outlet. It works, but it adds only 3 to 5 miles of range per hour. For most St. Louis drivers, that is not enough overnight recovery.
Level 2 (240V): A dedicated 240V, 40–50-amp circuit powers a Level 2 charger and adds 25 to 30 miles of range per hour. Most homeowners recover a full charge overnight. This is the installation our residential customers request most.
We assess your panel before quoting. Many St. Louis homes, particularly those in South City and the inner suburbs, were built with 100-amp panels that need upgrading before a Level 2 charger can operate safely. If a panel upgrade is needed, we handle that too. See our electrical panels page for details.
Typical installed cost for a Level 2 home charger in St. Louis runs $575 to $2,875, depending on circuit length, panel condition, and charger model. Jobs that require a panel upgrade add to that range. We provide a firm written estimate before any work begins.
Commercial EV Charger Installation St. Louis, MO
Parking lots, fleet garages, office buildings, and multi-tenant properties all have growing demand for on-site charging. Fielder handles the full scope: load calculations, conduit runs, trenching, breaker additions, and charger mounting. We own our equipment, including bucket trucks and trenchers, which keeps costs down for our customers.
St. Louis County ordinance now requires a percentage of commercial parking spaces to be EV-ready or charger-equipped in new developments. We work with your contractor or building manager to meet those requirements on time.
Permits and Inspections for EV Charger Installation in St. Louis
A dedicated 240V circuit for a Level 2 charger requires an electrical permit from the City of St. Louis Building Division or your county building department. St. Louis City and County adopted the 2023 National Electrical Code in January 2025. Under that code, GFCI protection is mandatory for all receptacle-type EV chargers, and conductor sizing for Level 2 circuits follows updated duty-cycle rules.
Fielder pulls the permit, schedules the inspection, and handles all code compliance. You do not manage that process.
Skipping the permit creates problems: home inspectors flag unpermitted electrical work at resale, and insurance claims tied to that work can be denied.

Do I Need a Panel Upgrade First?
If your home has a 100-amp panel or limited breaker capacity, likely yes. A 40-amp Level 2 charger requires a 50-amp dedicated circuit. We assess this during the free estimate so there are no surprises on installation day.
