NFPA 70E-2021 makes no mention of required PPE for levels below 1.2cal/cm^ 2 . While there is not enough energy to produce an arc flash hazard, we still recommend using the following table as a “best practice” to ensure safety from electrical shock hazards that are still present.
Incident Energy
PPE
Incident energy exposures up to 1.2 cal/cm²
