Commercial Electrical Contracting in Tampa Bay
When the power is out in a business, every hour has a number attached to it. Third Gen Electric handles tenant improvements, service and panel work, lighting retrofits, and code compliance for Tampa Bay businesses, offices, and commercial properties — scheduled around your hours, not ours.
Commercial Electrical Services
Commercial work lives or dies on sequencing: permits pulled early, rough-in coordinated with the other trades, and inspections scheduled so nobody is waiting on us. We work directly with owners, property managers, and general contractors, and we keep whoever is paying the bill informed about where the job stands.
- Tenant improvement (TI) build-out wiring
- Three-phase service and panel work — 120/208V and 277/480V
- Service, feeder, and switchgear upgrades
- Lighting retrofits and LED conversions
- Exit and emergency lighting installation
- Data, low-voltage, and structured cabling
- Dedicated equipment and machine circuits
- Permit pulling and inspection coordination
Exit and Emergency Lighting Is an Inspection Item
Emergency egress lighting and exit signs aren't a one-time install — the fire code requires a 30-second functional test at intervals not exceeding 31 days, plus an annual 90-minute test confirming the batteries carry the load for the full required duration, with written records kept for the fire inspector. Dead batteries in emergency fixtures are among the most common findings at inspection, and nobody notices until the inspector does. Self-testing fixtures satisfy the monthly test automatically and are usually what we recommend specifying.
Maintenance & Service Work
Most commercial electrical failures announce themselves well before they stop the business — a breaker that runs warm, a ballast that's been humming for months, a parking lot pole that's been dark since spring. Scheduled maintenance catches those while they're still cheap to fix, and we take after-hours service calls for the ones that don't wait.
- Scheduled preventive maintenance
- After-hours and weekend service calls
- Breaker, panel, and circuit troubleshooting
- Panel and connection inspections
- Ballast and LED driver replacement

Frequently Asked Questions
Common questions about commercial electrical services. Don't see yours? Give us a call — we're happy to talk through your project.
Can you work after hours so we don't have to close?
Yes. Most of the retail, restaurant, and office work we do happens in the evening, overnight, or on weekends specifically so the business keeps running. Tell us your hours and the constraints — a restaurant's prep schedule, an office's server room, a shop floor that can't lose power — and we'll build the sequence around them.
Can you handle a full tenant improvement build-out?
Yes, from permit through final inspection. That includes demo of existing circuits, rough-in coordinated with framing and HVAC, panel and feeder work, lighting, data and low-voltage cabling, device trim, and the inspections at each stage. We work as a subcontractor to general contractors as well as directly for owners and tenants.
What's involved in a commercial lighting retrofit?
We survey what's installed, calculate what the space needs, and replace or retrofit fixtures accordingly — typically converting fluorescent troffers to LED and rebalancing circuits afterward. Worth knowing that occupancy sensors, automatic shutoff, and daylight-responsive controls generally aren't optional on this work: the Florida energy code requires them along with lighting power density limits, and compliance has to be documented to the building department. Lighting is usually the largest load you can actually control — cooling is bigger in Florida, but you can't switch it off — which is why this is normally the fastest electrical payback in the building. Most of the work can be staged so the space stays usable.
Do you work with property managers and general contractors?
Regularly. We're used to working inside someone else's schedule, submitting what the GC needs for the permit package, coordinating with other trades at rough-in, and keeping a property manager updated on multi-tenant buildings where the work touches more than one space.
How often does exit and emergency lighting need testing?
Thirty seconds of functional testing at intervals no longer than 31 days, and once a year a full 90-minute discharge test — 90 minutes because that's how long the egress lighting itself has to last. Records have to be written down and produced for the fire inspector on request. The duty sits with the building owner, not the contractor, but we can carry out the testing and keep the log as part of your preventive maintenance so it isn't something you have to track. If your emergency lighting runs off a generator instead of batteries, it falls under a different standard with its own monthly load test.
Do you do three-phase work?
Yes. Three-phase service, panels, feeders, and equipment circuits are standard commercial work for us — motors, compressors, HVAC, commercial kitchens, and machine circuits included. If you're adding equipment, send us the nameplate data, and we'll confirm what the service needs to support it.
