When working with energized electrical equipment, knowing when PPE is required can prevent serious injury—and confusion. According to NFPA 70E Table 130.5(C), if you’re operating a breaker under normal operating conditions and it’s not the first time it’s being operated since installation or maintenance, the likelihood of an arc flash event is considered low—and PPE is not required.
However, at Shaw Consulting Services, we recommend a more conservative approach: PPE should always be worn when incident energy levels exceed 25 cal/cm², even if the standard doesn’t explicitly require it. Safety isn’t just about compliance—it’s about protecting people.
What Qualifies as a “Normal Operating Condition”?
NFPA 70E Section 110.2(B) outlines seven specific criteria. All must be met for equipment to be considered in normal operating condition:
- Proper Installation
Equipment must be installed in line with all applicable codes, standards, and manufacturer guidelines, including required clearances and safe egress. - Proper Maintenance
Maintenance must follow NFPA 70B and the manufacturer’s service instructions. Lack of documented maintenance invalidates the condition. - Rated for Available Fault Current
The equipment’s rating must match the available fault current at its location. - Used in Accordance with Listing and Labeling
It must be operated per manufacturer instructions and intended purpose. - Doors Closed and Secured
All doors must be properly closed and latched to prevent contact with live parts. - Covers in Place and Secured
No missing fasteners or unsecured panels—everything must be fully intact. - No Signs of Impending Failure
Look for visible damage, corrosion, arcing, overheating, or mechanical wear. If something looks off, it likely is.
