How many types of feeders are there that connect to a service panel?

The correct answer indicates that there are two types of feeders that connect to a service panel. These types are typically classified as "main feeders" and "sub feeders."

Main feeders are responsible for delivering the primary electrical supply from the utility to a service panel. This connection provides the power necessary for a residential or commercial building's electrical system.

Sub feeders, on the other hand, are used to distribute power from the main service panel to additional panels or separate areas within a building, such as garages or workshops. They function to extend the electrical supply beyond the main service panel.

Understanding these two types is crucial for assessing and designing electrical systems, ensuring proper load distribution and compliance with electrical codes. This knowledge is also essential for any electrical inspections required during property transactions or renovations.
