Arcing PIS?
Yes / No
Supplementary information:
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.

Supplementary Information:
A combination of voltmeter, VA and ammeter IA may be used instead of a wattmeter.
If a separate voltmeter and ammeter are used, the product of (VA x IA) is used to determine Resistive PIS
