Effective system load is used to determine the amount of propane required to operate appliances at a reduced demand and assumes the customer's appliances are:

• A. Operate at full demand only during typical operating cycles and do not operate simultaneously
• B. Operate at reduced demand continuously
• C. Operate at full demand for all cycles
• D. Off during peak hours

Answer: (A)

Effective system load relies on the idea that appliances don’t all peak at the same time. It estimates propane needs by treating each appliance as capable of drawing its full amount during its normal cycle, but ensuring they don’t operate simultaneously. This gives a realistic picture of peak demand because devices run in cycles and overlap is partial, not total. So, the reasoning described—full demand during typical operating cycles, with appliances not running at full demand all at once—best captures how propane use actually happens. It prevents overestimating the load that would come from adding every appliance’s full demand together, while still recognizing that individual appliances can reach their full use during their cycles.
