Calculated load of a feeder or service is described as which of the following?

Calculated load of a feeder or service is described as which of the following?

• A. True
• B. False
• C. Cannot be determined
• D. Unknown

Answer: (A)

The key idea here is that the calculated load of a feeder or service represents the actual, expected load the system must carry—not just the equipment’s maximum rating or nameplate value. It’s determined by adding up the connected loads, applying any demand factors and continuous-load adjustments, and then converting that total to current at the service voltage. This calculated load is the figure used to size wiring and overcurrent protection because it reflects what the system will realistically experience. That’s why the correct answer is that the calculated load is described as true: it is the real, design-based load the feeder or service must support, not a theoretical maximum or a vague estimate. It isn’t false or unknown because, with proper data and standard calculation methods, you can determine this value.
