Notes:
1. Short-term refers to no more than 96 consecutive hours per occurrence and no more than 15 occurrences in
a one-year period.
2. Pollution degree is as defined in IEC 60950. Pollution Degree 2 applies where there is only non-conductive
pollution that might temporarily become conductive due to occasional condensation.
