Industrial Electrical Contractor in Fresno and Central California
Industrial Electrical Services
Industrial facilities put heavier, more continuous demands on an electrical system than offices or retail space. Motors, compressors, refrigeration, conveyors, and process equipment need reliable three-phase power, properly protected circuits, and distribution that can grow as equipment is added.
Sebastian’s industrial electrical services include:
Power distribution and three-phase service for motors, compressors, and production lines (three-phase vs. single-phase power explained)
Service upgrades, switchgear, panels, and transformers when a facility adds equipment or expands (commercial electrical panel upgrades)
Equipment and machinery circuits, disconnects, and safety switches
Industrial and high-bay lighting with controls, inside the plant and across the yard
Standby generators and transfer switches to keep critical loads running during outages (types of commercial backup generators)
Surge protection for controls, drives, and sensitive equipment (what happens after a power surge)
Industrial Electrical Maintenance Services
Unplanned electrical failures cost industrial facilities far more than scheduled maintenance does. Sebastian’s industrial electrical maintenance services put panels, connections, equipment circuits, and lighting on a regular inspection and service schedule, so loose connections, overheating, and worn components are caught before they shut down a line.
Plant electrical maintenance is planned around your production calendar, with larger work scheduled for planned shutdowns, off shifts, or seasonal slow periods. For facilities that need a clearer picture of electrical hazards at each piece of equipment, we also support arc flash and electrical safety planning. Learn more about commercial electrical maintenance programs and what an arc flash study involves.
Cabling, Security, and Site Work From the Same Team
Industrial electrical projects rarely stop at power. The same crews that install your electrical service can run industrial network cabling and fiber, install access control and video surveillance for yards and loading docks, and handle underground conduit across large sites. See our industrial services for the full range, including low voltage installation, access control and security, and underground contracting.
Industrial Facilities We Serve
- Food and agricultural processing: Processing lines, packing houses, and refrigeration that run through harvest season
- Cold storage: Refrigeration loads, standby power, and controls where a power loss means lost product
- Warehouses and distribution centers: High-bay lighting, dock equipment, charging circuits, and wireless coverage across large floors
- Manufacturing: Equipment circuits, power distribution, and controls for production floors
- Large-format commercial sites: Projects like the Costco builds in Clovis and Elk Grove, where Sebastian completed electrical, underground, and site work with general contractor RMC in 94 days

Electrical Work Planned Around Production
The difference between an industrial electrician and a commercial electrician often comes down to planning. Industrial work has to fit around running equipment, shift schedules, and safety procedures. Sebastian’s approach:
- Walk the facility with your maintenance or operations lead to understand the equipment, loads, and schedule.
- Plan the work in phases so production keeps running, with tie-ins and shutdowns scheduled in advance.
- Coordinate lockout/tagout and safety procedures with your team before work starts.
- Document the finished work so your maintenance staff knows what was installed and where.

Industrial Electrical FAQ
What does an industrial electrical contractor do?
An industrial electrical contractor installs, maintains, and repairs the electrical systems that power plants, warehouses, processing facilities, and manufacturing floors. That includes three-phase power distribution, switchgear and panels, equipment circuits, industrial lighting, standby power, and scheduled maintenance, planned around production schedules and plant safety procedures.
What is the difference between an industrial and a commercial electrician?
The difference between an industrial and a commercial electrician is mostly the environment and the equipment. Commercial electricians focus on offices, retail, and similar buildings, while industrial electricians work with heavier three-phase loads, motors, process equipment, and controls in facilities that often can’t stop running. Sebastian does both, so one contractor can handle a plant floor and its offices.
Can electrical work be done without shutting down production?
Electrical work can often be done without shutting down production by phasing the project, working off shifts, and scheduling tie-ins for planned shutdowns. Some work, such as service upgrades, requires a short outage, and we plan those with your team well in advance.
Does Sebastian offer industrial electrical maintenance services?
