Should the feeder or service calculated load be less than or greater than the sum of the loads of the two largest pieces of kitchen equipment?

In the context of electrical loading for kitchens, it is essential to ensure that the feeder or service calculated load is greater than the sum of the loads of the two largest pieces of kitchen equipment. This requirement is based on the principles of demand factors specified in the NEC (National Electrical Code) to ensure adequate service capacity.

By calculating the feeder or service load to be greater than this sum, you are accounting for potential peak usage scenarios, ensuring that the electrical service can handle the maximum expected demand without risking overload conditions. It helps to provide a buffer for simultaneous operation and potential future expansions of kitchen equipment. Additionally, this practice aligns with safety standards, reducing the likelihood of power interruptions or equipment failure under load.

In contrast, having the feeder or service load be less than or equal to the load of the largest equipment could result in insufficient capacity, leading to overheating, circuit tripping, or damage to the systems due to excessive demand. Thus, making sure the calculated load is greater than the sum of the two largest kitchen equipment loads is crucial for both performance and safety in the electrical design of kitchens.
