Commercial · Franklin County & St. Louis, MO
Warehouses, shops, garages, and light-industrial spaces need real electrical: heavy-gauge branch circuits, 3-phase where required, overhead power drops on reels, high-bay LED lighting, and machine-specific circuits. CAS Electric wires these spaces across Franklin County and the Greater St. Louis area — Pacific, Washington, Union, Sullivan, St. Clair, Eureka, Wildwood, Villa Ridge, and Marthasville.
A working space is only as productive as its power infrastructure. Extension cords across a shop floor are a safety liability and a productivity drag. Proper power drops, correctly sized circuits at every workstation, and bright, uniform overhead lighting change how a shop or warehouse operates day-to-day.
We handle the full scope for small and mid-size industrial spaces: main distribution and sub-panels sized for future growth, dedicated machine circuits (including 3-phase for CNC, compressors, welders, and lifts), ceiling and column-mounted power drops on retractable reels or fixed hangers, 20A and 30A convenience receptacles at workstations, welding receptacles, and 240V/208V circuits where the machinery calls for them.
Lighting is a big part of the value: swapping metal-halide high-bays for LED high-bays typically cuts lighting energy 60–70% while doubling foot-candles on the floor. Combined with occupancy sensors and daylight harvesting where skylights allow, the payback is often 2–4 years.
Warehouse and shop wiring is quoted per project based on square footage, machinery list, and lighting scope. High-bay LED retrofits often qualify for Ameren Missouri BizSavers utility rebates that lower net cost.
We inventory your machinery, receptacles, and lighting needs — then build a distribution plan sized for today plus 25% growth headroom.
Itemized by area (main distribution, lighting, machine circuits, drops) so you can phase the work if needed.
Conduit, panels, circuits, drops, and lighting installed on schedule — after hours if needed to keep the shop running.
Local inspector signs off, we walk you through the distribution and labeling, and hand you as-built panel schedules.
Yes — high-bay LED retrofits and new installs are one of our most common shop upgrades. We handle the fixtures, wiring, controls (occupancy sensors, daylight harvesting), and any Ameren BizSavers rebate paperwork.
Yes. If you have 3-phase available at the panel, we can pull a dedicated circuit to the machine location, size the disconnect, and land the equipment. If you don't have 3-phase, we can talk through phase converters or a 3-phase service upgrade with Ameren.
Yes — retractable cord reels, fixed hangers, and drop cords over workstations, all with dedicated circuits and proper strain relief.
Usually yes. We phase the work, tie in new circuits during off-hours when possible, and coordinate any brief shutdowns around your production schedule.
Yes — 50A and 60A welding receptacles, dedicated 240V circuits, and appropriate disconnects at the outlet location.
