The National Electrical Code (NEC) sets the standards for safe electrical installations across the United States. As an industrial facility manager, staying up to date with the latest NEC codes for lighting can feel like a moving target. However, there are ways to get your facility into compliance without starting over from scratch. Here is an in-depth guide on how to get around updated NEC codes for industrial lighting.
Understanding the Code Changes
The first step is understanding exactly what has changed in the latest NEC industrial lighting codes. Major updates include:
Height Requirements
- The NEC now requires minimum height standards for installation of industrial luminaires. Previously, there was more flexibility on mounting height.
- For example, high bay luminaires now must be mounted at least 10 feet off the ground in most areas. This reduces glare and provides safer clearance.
Spacing and Layout
- More attention is paid to uniformity of lighting layout under the new codes.
- The standards aim to eliminate dark spots through proper pole spacing and mounting locations.
- Simply swapping out old luminaires for new may not meet code if the overall lighting layout is uneven.
Light Levels
- The acceptable light levels, measured in lumens, have been increased in many industrial spaces.
- More light is required in detailed manufacturing areas, warehouses, and corridors.
- This ensures workers have sufficient illumination to perform tasks safely and accurately.
Performing Code-Compliant Retrofits
When upgrading older industrial lighting systems, you can avoid a complete overhaul by taking a strategic approach:
1. Evaluate the Existing Layout
- Survey your existing industrial lighting layout and take detailed measurements.
- Identify areas, such as manufacturing zones, that now require higher light levels based on the updated NEC codes.
- Determine if you need to adjust pole locations or add supplemental lighting to meet code.
2. Install New Code-Compliant Fixtures
- Replace outdated industrial luminaires with new ones that meet current standards.
- Consult manufacturing specs to verify the light levels and mounting heights comply with latest NEC.
- Reuse existing electrical and pole infrastructure as much as possible to avoid major construction.
3. Adjust and Redistribute As Needed
- After installing new LED luminaires, examine the overall light distribution.
- Make adjustments like raising poles, adding supplemental lights, or relocating poles to achieve uniformity.
- Correct any remaining dark spots or glare issues that are against code.
4. Have Updated Lighting Layout Certified
- Once the lighting installation meets all NEC industrial standards, have it certified by the local building authority.
- This ensures your lighting layout complies with the updated codes prior to final inspection.
The Importance of Staying Up to Date
While updating industrial lighting to meet new NEC codes can be disruptive, it is extremely important for safety and efficiency. Here are some key reasons to stay compliant:
-
Ensures OSHA Compliance: Updating lighting is required to meet federal Occupational Safety and Health Administration (OSHA) standards. This reduces accidents and injuries.
-
Improves Working Conditions: Proper industrial lighting enhances visibility, reduces eye strain, and creates a better workplace. This can improve productivity.
-
Saves Energy: Modern LED luminaires use less power than outdated HID lighting. Upgrading can significantly reduce energy costs.
-
Avoids Fines: Bringing your facility up to code avoids citations, violations, or fines from local authorities during inspections.
Final Thoughts
Adapting older industrial lighting systems to meet new NEC codes can require planning and investment. However, the long-term benefits for your facility and workforce make it well worthwhile. By taking a strategic approach and utilizing code-compliant retrofit techniques, industrial managers can achieve compliance without starting from zero. Keeping up with evolving NEC industrial lighting standards ensures optimal safety, visibility, and energy efficiency.
