The practice of aggregating multiple loads for calculation purposes is called?

• A. Combining loads
• B. Open, individual overhead conductors
• C. Feeder and branch-circuit conductors
• D. Maximum volts to ground for luminaires

Answer: (A)

Combining loads is the act of adding together the wattages (or currents) of all individual devices or circuits that may operate, to determine a single total load for design calculations. This total is what you use to size feeders, panels, and overcurrent protection, ensuring the electrical system can handle the expected demand. In practice, you often start with the sum of all connected loads and then apply factors like diversity or demand to reflect that not all loads run at full power simultaneously.

Other choices describe things that aren’t about summing loads: open, individual overhead conductors refers to a physical wiring method, feeder and branch-circuit conductors describe types of conductors rather than calculation methods, and maximum volts to ground for luminaires concerns voltage/grounding rather than aggregating loads.
