Limited approach boundary 50v
NettetThe arc flash boundary, or restricted approach boundary, changes depending on the potential arc flash hazard. The arc flash boundary is calculated to 1.2 calories/cm2 of incident energy. That’s the distance where a worker without appropriate PPE would receive second-degree burns. NettetThe limited approach boundary and the restricted approach boundary are often found on an arc flash label provided an arc flash risk assessment has been completed at the …
