Industrial Electrical Contractor for the St. Louis Manufacturing Corridor
Kay-Bee Electric has been doing industrial electrical work in St. Louis for more than 75 years. Industrial service installations run differently than commercial work: large power services, three-phase distribution, and clients who cannot tolerate downtime on the production floor. Our master electricians and journeymen know the tolerances that industrial facilities require, and they work on permit under the supervision of our in-house engineering staff.
Common industrial electrical scopes we run across St. Louis County, St. Charles County, and Jefferson County:
- 3-phase service entrance upgrades, switchgear, and feeder runs for new production equipment
- Motor control centers (MCCs), variable frequency drives (VFDs), and soft-start installations
- NFPA 70E arc-flash studies, labeling, and PPE coordination for plant electrical safety
- Uninterruptible Power Supplies (UPS), emergency lighting, and back-up power systems for production continuity
- Hazardous-location wiring per NEC Article 500 where flammable processes or dusts are present
Our engineers and designers have scope across every aspect of an industrial facility, from the service entrance to the last branch circuit on the production floor. Learn more about industrial electrical safety at NFPA.org and process energy efficiency at Energy.gov.
Emergency Power, Damage Recovery, and Plant Continuity
Your emergency power requirements can all be installed by Kay-Bee, including emergency lighting, Uninterruptible Power Supplies (UPS), generator paralleling, and full back-up power systems. Our engineering staff will work with you to establish your requirements, size the generator and ATS correctly, and make sure your installation keeps the plant up and running through utility outages, voltage sags, and weather events.
- Free electrical construction cost estimation on new service entrance and equipment installations
- Damage recovery after fire, flood, lightning strikes, or production equipment failures
- Generator sizing, ATS coordination, and load-bank testing per NFPA 110 on critical loads
- 24/7 emergency response on contract for production-down events and equipment failures
- Scheduled maintenance agreements with quarterly panel infrared scans and switchgear inspections

Frequently Asked Questions
Planning a service upgrade, an equipment install, or a generator project for your plant? Call (314) 837-3308 or request a site walk-through across the St. Louis manufacturing corridor.
Yes. We can perform the arc-flash hazard analysis (or coordinate with your existing engineering consultant), produce the labels and the boundary calcs, and update them whenever your service entrance or major loads change. Arc-flash labeling is required on every panel, switchgear, MCC, and disconnect under NFPA 70E. We can also coordinate the PPE category requirements with your plant safety lead so your team has the correct gear on the floor.
Yes, on contract. Industrial clients with a signed service agreement get 24/7 after-hours emergency response for production-down events, generator failures, and equipment outages. The response window depends on the agreement tier. For plants where unplanned downtime costs more than scheduled response time, we recommend the higher tier with on-call rotation. Talk to one of our representatives about the options that fit your operation.
Call us. We handle facility damage recovery from fire, flood, lightning strikes, accidents, and equipment failures. We will inspect the affected service entrance, switchgear, and branch wiring, determine what is salvageable versus what needs replacement, coordinate with your insurance adjuster on the scope and the cost, and run the rebuild on permit so your plant comes back online with documented, code-compliant work.
