Ron:
There are lots of 240V installations that have short circuit currents in excess of 25kA and fault clearing time greater than 2 cycles.
and
Notes:
1. Maximum of 25 kA short circuit current available, 0.03 second (2 cycle) fault clearing time.
What level of PPE would those examples require?
Table 130.7(C)(9)(a) Hazard/Risk Category Classifications
Where is this information located?
Thanks!!
