What is required for the installation of a subpanel in a residential home?

The requirement for installing a subpanel in a residential home involves proper labeling and a feeder circuit from the main panel. This is essential for ensuring convenience and safety in the electrical system. Proper labeling is necessary for identifying the circuits connected to the subpanel, which aids in maintenance and troubleshooting. It helps anyone working on the electrical system to understand which circuits are controlled by the subpanel and prevents confusion or accidents during repairs or modifications.

The feeder circuit, which consists of appropriately sized conductors and a breaker from the main panel, is critical for providing adequate power to the subpanel. This ensures that the subpanel can handle the electrical load safely and efficiently. It also involves adhering to specific code requirements regarding wire size, which must be determined based on the subpanel's load demands and the distance from the main panel.

In summary, the requirement of having both proper labeling and a feeder circuit from the main panel ensures a safe, functional, and compliant installation of a subpanel within a residential setting.
