Five pieces of kitchen equipment in a restaurant would have a feeder demand factor of ___ percent.

Five pieces of kitchen equipment in a restaurant would have a feeder demand factor of ___ percent.

• A. 65 Percent
• B. 70 Percent
• C. 80 Percent
• D. 90 Percent

Answer: (B)

Feeder demand factor is used to size feeders by applying a percentage to the sum of the connected loads for a group of electrical equipment. It reflects that not all pieces will be on at the same time, even though they are all capable of drawing power. For a restaurant with five kitchen pieces, a 70% factor is the standard estimate because, with several items, the likelihood of simultaneous maxing out is low enough to justify reducing the total load, but high enough to be realistic for typical kitchen use. So, if each piece is rated 2 kW, the total connected load is 10 kW. Applying the 70% feeder demand factor gives 7 kW as the feeder load. At 240 V, that’s about 29 A, guiding you to size the feeder around 30 A or more. The other percentages would either understate the demand (65% would give a smaller feeder than typical) or overstate it (80% or 90% would push you toward unnecessarily larger feeders, as five kitchen loads rarely reach near-full simultaneous demand).
