The equipment I am working on is not labeled, how do I select the right arc flash PPE based on voltage?
How do I select the right arc flash PPE based on voltage?
Selecting appropriate arc flash PPE knowing only the voltage is impossible. You must have the fault clearing time and the available fault current as well as the voltage. If the equipment is in normal operating condition, you may be able to utilize the NFPA 70E 130.7 tables to select appropriate arc rated PPE.
