Arc Flash Boundary Chart - When an arc flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm 2. 2 in.) 0.2 m (0 ft. Employers must provide appropriate arc flash clothing to employees who work in areas with potential electrical hazards. 0 in.) 2.5 m (8 ft. These boundaries trigger multiple requirements in 70e including but not limited to determining the type and level of ppe and qualifications required to cross into each level. Web this online arc flash calculator is based on ieee std.
Reference the 2015 nfpa 70e¢ç: When an arc flash hazard exists, an approach limit from an arc source at which incident energy equals 1.2 cal/cm 2. Web the table below has been adapted from nfpa 70e, table 130.4 (e) (a) shock protection approach boundaries to exposed energised electrical conductors or circuit parts for alternating current systems. The arc flash boundary, or restricted approach boundary, changes depending on the potential arc flash hazard. Web under nfpa 70e, there are three boundaries that are observed—limited approach, restricted approach, (the shock protection boundaries) and arc flash boundary.
