What is the requirement for feeder conductors in a new restaurant?

Feeder conductors are responsible for carrying electrical power from the service equipment to various distribution points throughout the facility, such as panels or sub-panels. In a restaurant setting, it's important to ensure that the electrical system can handle the varying loads required by kitchen equipment, lighting, and other appliances.

The National Electrical Code (NEC) allows for feeder conductors to have less ampacity than service conductors. This is because the feeders are designed to distribute power to specific areas or panels rather than serving as the main entry point for electrical supply. Consequently, while it is essential that feeder conductors can safely handle the loads they are intended to supply, they are not mandated to exceed the ampacity of the service conductors.

This approach provides flexibility in designing the electrical system of the restaurant, allowing for potential adjustments based on the specific demands of the facility. It's also important to calculate feeder sizes based on the actual load that will be fed, ensuring safety and compliance with NEC standards. Thus, having feeder conductors with less than or equal ampacity compared to the service conductors is permissible and practical within the parameters of electrical installation standards for restaurants.
