What Is an Industrial Electrician and Why Are They Essential?

What is an industrial electrician? An industrial electrician is a professional who can install, maintain, and repair electrical systems in heavy-duty environments, including factories, processing facilities, manufacturing plants and large industrial plants, and is different from a commercial electrician for several reasons, including the amount of voltage the industrial electrician works with.  

Industrial electricians play a critical role in keeping material handling systems, production lines, and process equipment operating in a safe and reliable manner. The daily work of an industrial electrician ranges from installing electrical wiring and motor controls to performing diagnostics on control panels, drives, and programmable logic controllers (PLCs).  

Inspections and maintenance help identify issues such as circuit overloads, failing components, and deteriorating insulation before they can cause unplanned shutdowns.  

Understanding Electrical Codes and Standards 

Electrical codes and standards keep everyone safe, but they are crucial in industrial settings because of higher power levels and more complex systems. In the United States, the National Electrical Code (NEC) sets the baseline requirements for safe installation of electrical equipment to reduce the risk of fire, shock, and arc-flash incidents. 

Industrial electricians must know how to read blueprints, single-line diagrams, and panel schedules. They must also know how to apply code requirements to real-world installations. They ensure that conductor sizing, overcurrent protection, grounding, bonding, and equipment clearances all align with NEC and applicable local codes. 

Because codes change every year due to changes in technology and safety expectations, the electricians at Dubak Electrical Group attend ongoing education to remain up to date with the latest standards and deliver design-build, maintenance, and electrical installations that meet all relevant codes and regulations.  

Power Distribution in Industrial Settings 

Industrial electricians implement and maintain power distribution strategies that handle large loads, multiple voltage levels, and mission-critical processes. Some of the factors they must work with include:  

• Main switchboard sizing 

• Coordination of protective devices 

• Redundancy 

• Safe feeder and bus duct routing, usually through congested plant spaces 

If the power distribution is not correct, it is not reliable enough to run heavy-duty loads, and safety becomes a concern.  

Additionally, the distribution system must have the ability to handle power interruptions and quality issues, which means adding generators and uninterruptible power supply (UPS) systems. Preventive power maintenance programs also help businesses through utility outages and reduce the risk of production losses.  

Dubak’s electricians handle central switchboard installations, bus duct, and riser feeders, and power and control wiring for processing and manufacturing equipment, ensuring that power is delivered where and when it is needed. 

Maintenance and Troubleshooting of Industrial Machinery 

Because industrial machinery runs for more hours and is more powerful than most commercial equipment, it is more prone to wear, vibration, and thermal cycling. Challenges include the breakdown of insulation, motor failures, nuisance tripping, control circuit faults, and issues with variable frequency drives (VFDs) and soft starters. 

Industrial electricians use a combination of electrical troubleshooting techniques, such as megger testing, thermal imaging, and circuit tracing, to pinpoint problems. Dubak’s teams, for example, provide contract maintenance and emergency services that cover everything from faulted cables and failed breakers to malfunctioning motor control center (MCC) buckets and panel components. 

To keep equipment efficient and longer lasting, it must have preventative maintenance. Programs often include inspections, torque checks, enclosure cleaning, infrared scans for hot spots, and verification of protective device settings, all of which help industrial electricians correct issues before they become downtime events. 

Safety Protocols in Industrial Electrical Systems 

Safety protocols protect people and equipment where high energy levels and complex systems can create serious hazards. These protocols typically address lockout/tagout (LOTO), arc-flash risk, grounding practices, and safe work distances around energized equipment. 

Regular safety audits and documented procedures help maintain a culture of electrical safety. By pairing strong safety protocols with proper equipment maintenance, industrial electricians help reduce accidents, protect infrastructure, and maintain regulatory compliance across the industrial environment. 

Safety protocols include:  

Core Work-Practice Protocols 

• De-energize circuits prior to work when feasible, per OSHA 1910.333 and NFPA 70E guidance.  

• Verify the absence of voltage with an appropriate tester after lockout/tagout and before touching conductors or parts. 

• Maintain required approach distances to exposed energized parts using NFPA 70E shock and arc-flash boundaries. 

• Use insulated tools and nonconductive equipment when working on or near electrical systems. 

Lockout/Tagout and Hazardous Energy 

• Apply lockout/tagout (LOTO) on all energy-isolating devices before servicing or maintenance so equipment cannot be re-energized unexpectedly. 

• Attach durable tags and locks that identify the worker and keep them in place until work is complete and the area is clear. 

• Follow written LOTO procedures that include shutdown, isolation, verification of zero energy, and safe re-energization steps. 

Personal Protective Equipment (PPE) 

• Wear appropriate arc-rated clothing, voltage-rated gloves, eye/face protection, and head protection suited to the calculated arc-flash and shock risk. 

• Inspect PPE regularly for damage such as tears, cracks, and contamination and remove defective items from service. 

• Use additional protection such as insulated mats, shields, and barriers when working around high-voltage or arc-flash-risk equipment. 

Hazard Identification and Work Environment 

• Conduct a task-specific risk assessment before starting work to identify shock, arc-flash, and mechanical hazards. 

• Keep work areas dry, clear of conductive clutter, and avoid working near water or grounded metal when possible. 

• Ensure proper grounding and bonding of equipment and cords, and remove damaged cords, plugs, and enclosures from service. 

Training, Signage, and Administrative Controls 

• Maintain current training in NFPA 70E, OSHA electrical standards, emergency response, and company-specific procedures for all qualified electricians. 

• Clearly mark hazardous locations, restricted areas, and electrical rooms with posted warning signs, barricades, and, when needed, attendants. 

• Report and correct electrical hazards promptly and encourage a stop-work culture when conditions are unsafe. 

The Role of Automation and Control Systems 

Automation and control systems are now central to how modern manufacturing plants and process facilities operate. PLCs, distributed control systems (DCS), and human-machine interfaces (HMIs) monitor inputs from sensors, execute logic, and control motors, valves, and actuators to keep processes within tight tolerances. 

Industrial electricians work hand in hand with control and automation engineers to integrate and maintain these systems. Dubak Electrical Group’s control and automation group designs and fabricates control panels, performs PLC programming, and develops HMIs to give operators intuitive insight into their systems. 

To support automation systems, industrial electricians need skills that go beyond basic electrical wiring. They understand communication networks, instrumentation, I/O mapping, and the interaction between field devices and control hardware, along with the ability to troubleshoot electrical and logic-related issues. 

Advancements in Wiring and Motor Control Systems 

Modern wiring systems in industrial settings provide capacity, flexibility, maintainability, and safety. Advanced wiring techniques include prefabricated assemblies, modular skids, and organized cable tray routing to simplify installation and future modifications. 

Dubak Electrical Group leverages prefabrication and modular construction through its associated brands to accelerate schedules and improve quality control on complex projects. These approaches help reduce on-site labor time and minimize errors, all while delivering clean, well-organized wiring systems that are easier to inspect and maintain. 

Motor control systems have also evolved significantly, moving from simple across-the-line starters to sophisticated MCCs with integrated VFDs, soft starters, and networked controls. Industrial electricians understand motor protection, coordination, and control strategies to ensure motors start smoothly, run efficiently, and have protection against faults. 

Industrial vs. Commercial Electrical Work 

Industrial and commercial electrician roles require strong electrical fundamentals. However, they serve different sectors and face distinct challenges. Commercial electricians focus on offices, retail, schools, and similar facilities, dealing with standard building wiring, lighting, and power distribution at comparatively lower complexities. 

Industrial electricians work in heavy-duty environments such as manufacturing plants, food and beverage processing, steel production, and wastewater treatment facilities. They handle higher voltages, more complex control systems, and specialized equipment. 

While both roles are vital, industrial facilities require a dedicated electrical contractor who has extensive industrial expertise for the unique demands of manufacturing.
