C22 2 No 30 for Canada
Pollution Degree 2
Normally only non-conductive pollution occurs Occasionally, a temporary conductivity
caused by condensation must be expected
Overvoltage Category III Distribution level, fixed installation, with smaller transient overvoltage than installation
category IV (Primary supply level)
MPORTANT I
For this CSA rating to be valid, the circuit board must be mounted in a certified Killark one inch model Y-3 conduit outlet box.
