What is not a method of determining power requirements?

• A. Using estimated load requirements
• B. Using a load table
• C. Conducting a site survey
• D. Reviewing historical data

Answer: (A)

Determining power requirements should be based on actual, documented loads rather than guesses. Using estimated load requirements isn’t a reliable method because it hinges on assumptions about what will be used, when, and to what extent, which can lead to over- or under-sizing and potential safety or efficiency issues. A load table provides established values for equipment or scenarios, helping you anchor calculations to known quantities. Conducting a site survey identifies every load on the system and how it operates in real conditions, capturing items that might be missed by memory or paperwork. Reviewing historical data shows how loads have behaved over time, informing demand patterns and peak requirements. When precision matters, you combine these data-driven methods to determine a solid, safe, and economical power requirement. Rough estimates might be used early for budgeting, but they don’t substitute for measured or documented loads in design.
