If during the monthly emergency generator test a critical procedure interrupts the testing of the automatic transfer switches and some of them do not get tested at that time, must the untested switches be tested prior to the next scheduled monthly generator test?
Yes. Standard EC.7.40 requires that all automatic transfer switches on the emergency system be exercised 12 times a year, with testing intervals not less than 20 days and not more than 40 days apart.
