How to Drastically Increase Your Safety and Avoid Costly Fines by Using Proper Industrial Wiring Standards

Industrial electrical systems can be extremely dangerous if not installed and maintained properly. Using improper wiring or failing to follow safety codes can put workers and facilities at serious risk. However, adhering to industrial wiring standards can help drastically increase safety and avoid potentially massive fines from regulatory agencies. Here's what you need to know about using proper wiring standards in industrial settings:

Why Industrial Electrical Standards Matter

Industrial facilities have unique electrical demands compared to residential or commercial buildings. Heavy machinery, high-power equipment, and sensitive electronics require robust electrical systems designed specially for the application.

Failure to follow electrical codes and use specified wiring can lead to:

Clearly, maintaining proper industrial electrical systems is extremely important for both safety and avoiding costly penalties.

Key Standards for Industrial Electrical Wiring

While residential wiring focuses on 120V circuits, industrial systems often use higher voltages and three-phase power. Specific wiring guidelines must be followed:


The NFPA 70E standard covers safety procedures and personal protective equipment for working on industrial electrical systems. It provides methods for safely de-energizing equipment, verifying deactivation, and guarding against arc flash hazards. Following 70E is mandatory for compliance with OSHA regulations.

UL Standards

The Underwriters Laboratories (UL) certifies electrical components for safety. Look for UL listing marks when selecting wiring, circuit breakers, panels, and other parts to ensure they meet requirements. UL 508A covers industrial control panels, for example.

NEC Article 675

Article 675 of the National Electrical Code (NEC) sets specific rules for industrial machinery wiring. It covers conduit fill capacity, ampacity selection, motor overload protection, and disconnection means. Local jurisdictions enforce NEC codes.

IEEE 3007.2

The IEEE 3007.2 standard focuses onArc Flash Analysis, providing methods to calculate potential arc flash energies and determine proper protective equipment. Conducting arc flash analysis on industrial systems helps quantify risks.

Key Wiring Safety Steps

Following proper industrial wiring standards comes down to a few vital steps:

Avoiding Costly Mistakes

Some common industrial wiring mistakes result in injuries or regulatory actions:

Always take electrical work seriously and use certified components and trained professionals. Reference official standards during any industrial electrical project. Adhering to codes and best practices will drastically improve safety and help avoid both tragic accidents and expensive OSHA fines.
