Is arc flash required for 208v?

The available fault current can be well over 100 kA. At these locations, there is definitely an Arc Flash (and blast) hazard. However, a low power source such as a 45 kVA 480 - 208 V distribution transformer most likely will not have enough energy to have a arc flash be self sustaining.
