Modified Appendix A to indicate power quality measurements are to be made on 120V 60Hz, 240V 60Hz and 230V 50Hz test power prior to any testing and align criteria with CTL-OP-0110. 3 S: y" K0 _. \2 h$ r5 |5 l1 A
Clarified circuits with larger power capacity are to be monitored during tests, or verified annually to confirm requirements with the test standard.
