Generator capacity shall be adequate to permit operation of essential communications for a period of how many hours without refueling?

• A. 72 consecutive hours
• B. 24 hours
• C. 96 hours
• D. 48 hours

Answer: (A)

The requirement focuses on how long a generator must keep essential communications operating without refueling. The standard answer is 72 consecutive hours, or about three days. This length gives a practical resilience window during power outages or when fuel resupply is delayed, ensuring critical communications stay up while crews arrange refueling or alternative power. Shorter durations, like a day or two, risk gaps in communication during longer outages, while a much longer duration would demand significantly more fuel and is not the minimum standard typically mandated. So, the generator capacity must support essential comms for 72 hours without refueling.
