Key Takeaways

  • Excel Electrical Technologies has been serving the Chicagoland area (Cook, Will, and DuPage Counties) since 2000.
  • Industrial electricians specialize in high-voltage equipment, automation (PLCs), and minimizing production downtime in factories and plants.
  • Commercial services focus on small to medium businesses, providing “whole package” solutions like 3-phase wiring and EV rapid chargers.
  • Safety and code compliance (NEC/OSHA) are the foundations of every project to protect property and people.

When the lights go out at home, it’s an inconvenience. When the power goes down in a business, factory or industrial plant, it can mean thousands of dollars lost per hour, safety hazards for workers, and equipment damage that takes weeks to repair. That’s exactly why industrial electricians exist, and why choosing the right electrical partner matters more than most facility managers realize. Just like you rely on a trusted IT service provider like TechKooks to keep your systems running, your business deserves an electrician you can count on just as much.

At Excel Electrical Technologies, we’ve been providing industrial, commercial, and residential electrical services to the Chicagoland area since 2000. Backed by a 10-year workmanship warranty and a 5-year warranty on supplied parts, our team of licensed professionals is built around one goal: keeping your facility safe, compliant, and running without interruption.

What Makes Industrial Electricians Different

An industrial electrician is not simply a residential electrician who works in a bigger building. These are highly specialized maintenance professionals trained to install, troubleshoot, and repair complex electrical systems in demanding environments such as:

  • Manufacturing plants and assembly lines
  • Power generation facilities
  • Chemical refineries and processing plants
  • Food production and distribution centers

Unlike residential work, the industrial environment introduces high-voltage equipment, intricate control systems, and heavy-duty machinery that require a different depth of knowledge entirely. Add in the presence of hazardous materials, extreme temperatures, and the constant pressure to minimize production downtime, and it becomes clear why strict adherence to OSHA safety standards and the National Electrical Code (NEC) is not optional. It’s the foundation of every job.

Key Areas of Industrial Electrical Work

Machinery and Equipment Installation

Industrial electricians handle the full electrical buildout for manufacturing equipment. This includes wiring for motors, installing disconnects, and designing and connecting distribution systems that can handle the demands of continuous heavy-duty use. Proper installation from the start prevents failures down the line and keeps your machinery running at peak capacity.

Automation and PLC Systems

Modern manufacturing runs on automation. Programmable Logic Controllers (PLCs) are the backbone of that automation, managing everything from conveyor speeds to robotic arm sequences. Industrial electricians work directly with PLC systems to install, configure, and maintain them, ensuring your automated processes stay in sync and production targets stay on track.

Troubleshooting and Diagnostics

When something goes wrong in an industrial setting, finding the cause quickly is critical. Industrial electricians use specialized tools including ammeters, voltmeters, and thermal scanners, to identify faults in complex circuits, drives, relays, and breakers. A precise diagnosis means faster repairs and less time offline.

Preventive Maintenance

The most expensive electrical failure is the one you didn’t see coming. Routine inspections catch small problems before they become costly shutdowns. Preventive maintenance programs include checking connections, testing equipment under load, inspecting insulation, and identifying “mystery” electrical issues that don’t yet show obvious symptoms but are developing into serious risks.

Commercial vs. Industrial: Choosing the Right Partner

Not every electrician is qualified for every job. Here’s a quick breakdown of who does what and why it matters:

Commercial Electricians focus on small to medium-sized businesses and institutions. Services in this space include:

  • Cat 5e/6 Ethernet cable runs for networking infrastructure
  • 3-phase wiring at 208 and 240 volts for commercial equipment
  • Lighting automation and energy management systems

Construction Electricians specialize in new builds. Their work centers on installing systems within new frameworks: pulling wire, setting conduit, and establishing grounding systems before walls go up. Their expertise ends largely when the building is occupied.

Industrial Electricians take over where construction leaves off, managing the ongoing maintenance, repair, and optimization of complex machinery and electrical systems throughout the life of a facility.

Excel Electrical Technologies bridges all three. Whether you’re a business owner, a property manager, or running a full-scale production facility, our licensed team delivers expert service across every category.

Property Management: Reliable Electrical Upkeep for Real Estate

For property managers overseeing multi-unit residential or commercial real estate, having a dependable electrical contractor isn’t just convenient. It’s essential. Tenant satisfaction, code compliance, and property value all depend on electrical systems that work consistently and safely.

Excel Electrical Technologies acts as a trusted extension of your property management team. Our property services include:

  • Common area maintenance: Laundry rooms, exit signs, hallway lighting, and landscape lighting
  • Administrative support: Clear documentation of all maintenance tasks, upfront estimating, and organized billing that simplifies your records
  • Code compliance: Ensuring every rental unit and shared space meets current NEC and local code requirements to protect tenants and protect your liability

We respond promptly, communicate clearly, and leave every job site clean, because your tenants and your reputation deserve nothing less.

The Future of Power: EV Chargers and Modern Upgrades

The electrical demands on homes and businesses are growing. Between electric vehicles, high-draw appliances, and modern smart systems, many older electrical panels simply weren’t designed for today’s usage. Upgrading now prevents bigger problems later.

EV Charger Installation

Electric vehicle adoption is accelerating. Excel installs rapid EV chargers for both residential and commercial properties, giving homeowners the convenience of overnight charging and giving businesses the ability to attract EV-driving customers and employees. We handle everything from the panel assessment to the final installation and inspection.

Panel Upgrades

We upgrade circuit breaker panels from 100 to 800 AMPs, a critical service for any property that experiences:

  • Frequently tripped breakers
  • Flickering or dimming lights under load
  • An older fuse box that hasn’t been updated in decades
  • New appliances or machinery that demand more power than the current system can deliver

Safety Inspections

An outdated or improperly installed panel is a fire hazard. Our safety inspections identify failing components, overloaded circuits, and panels that won’t pass code before they become emergencies. We give you a clear picture of what’s safe and what needs attention, with no surprises and no hidden costs.

Frequently Asked Questions

Do I need an electrician, or can this issue wait? If you’re noticing flickering lights, warm outlets, burning smells, or breakers that trip repeatedly, do not wait. These are warning signs of deeper electrical issues that can escalate into fires or electrocution hazards. When in doubt, have a licensed electrician assess the situation. The cost of an inspection is far less than the cost of an emergency.

Is my electrical panel outdated or unsafe? Signs your panel may be failing include frequent trips, physical rust or burn marks, a panel that feels warm to the touch, or a system that simply can’t keep up with your power needs. Panels older than 25 to 30 years warrant a professional evaluation.

Are EV chargers or surge protectors worth the investment? Absolutely. A whole-home or whole-facility surge protector protects thousands of dollars of electronics from power spikes. EV chargers add convenience and long-term value. Both are investments that pay for themselves over time.

Do I need permits or inspections for electrical upgrades to my business? In most cases, yes. Unpermitted work can void insurance coverage, create liability, and cause problems when it’s time to sell or lease a property. Excel handles all permitting and code compliance as part of every job, so you’re protected from day one.
