Supplementary information:
Note 1: An Arcing PIS requires a minimum of 50 V (peak) a.c. or d.c. An Arcing PIS is established when the
product of the open circuit voltage (V
p
) and normal operating condition rms current (I
rms
) is greater than 15.
Note 2: Assumption: All circuits inside the equipment enclosure are declared as arcing PIS.
