AFB stands for which term in arc flash terminology?

Explanation:
Arc Flash Boundary is the distance from live equipment within which an arc flash could deliver enough energy to cause a burn. This boundary is defined so that the incident energy at that distance is 1.2 cal/cm^2, which is the threshold used to determine the level of arc-rated PPE and safety precautions required. Knowing this boundary helps you plan safe work practices and establish when PPE must be worn. The other terms aren’t standard arc flash terminology, so they don’t describe the protective distance used in NFPA 70E.
