The EOOW conducts self-tests per hour at which rate?

• A. 6 self-tests
• B. 18 self-tests
• C. 24 self-tests
• D. 12 self-tests

Answer: (D)

Regular self-testing cadence ensures alarms and protective circuits stay functional while the EOOW performs duties. If self-tests occur 12 times in one hour, that’s one test every 60/12 = 5 minutes. This cadence provides timely detection of faults without overly interrupting normal operations. Other rates change the balance: 6 tests per hour would be every 10 minutes, 18 per hour about every 3 1/3 minutes, and 24 per hour every 2.5 minutes. Each option alters how often a fault could be caught versus how much time is spent testing, making 12 per hour the most practical regular interval.
