A start .and stop condition that will duplicate actual in-service operation shall be introduced for
this phase of the test. A minimum of twenty "start-stops" at the end of each hour's test is re-
quired. The deenergized period shall be of sufficient duration so as to permit the equipment
under test to come to a complete rest. The rest period shall not exceed 30 seconds.
