Will be doing NFPA 70E training with a mechanical service contractor who has HVAC technicians working on equipment typically operating at 480V and less. As you can expect, most of the commercial locations where they do service do not have Arc Flash Labels on their equipment. Per NFPA 70E, if an incident energy calculation has not been done, then the PPE Category method should be used for determining Arc Flash PPE. However, information such as the available fault current and clearing time are normally never available and trying to get this information would be extremely difficult. Just trying to be real! So looking for guidance on what they need to do to protect the workers. Ran across this document from the Mechanical Contractors Association of America:

What is basically states is when working on or around HVAC equipment at 480V and less that Category 2 PPE is required unless a risk assessment says it can be lower.
Thoughts?
