Demand factors for commercial electric cooking equipment: Do they exist in practice?

• A. Yes
• B. No
• C. Only sometimes
• D. Never

Answer: (A)

Demand factors exist in practice because electrical design uses them to size feeders and service based on how loads actually occur, not just the sum of nameplate ratings. In a commercial kitchen you might have many electric ranges, ovens, fryers, and other appliances, and they rarely all run at full rated current at the same time. By applying a demand factor schedule, engineers estimate a realistic maximum load for design, reflecting that simultaneous use is common but not full-load everywhere all the time.

These factors come from electrical codes, standards, and manufacturers’ data, and they’re routinely used to determine required service and conductor sizing. While usage can vary with menu, time of day, and events, the established practice is to apply these factors to avoid oversizing while still ensuring reliable operation. That’s why the correct answer is that demand factors do exist in practice.
