What runs from the electrical supply to the house wiring?

The term that refers to the connection from the electrical supply to the house wiring is "service." In residential electrical systems, service encompasses the entire setup that brings electricity from the utility provider into the home. This includes the service drop (the overhead or underground wiring), the meter that measures electrical usage, and the main electrical panel that distributes electricity throughout the house.

The service setup is crucial because it dictates how electricity is delivered safely and efficiently to all the electrical circuits within the house. This portion of the electrical system is responsible for converting external electricity—typically at high voltage—into a usable form for household appliances and systems, ensuring that the home's electrical needs are met.

Understanding the function of service helps clarify the roles of other elements like junction boxes, which are junction points for wires and connections within the house, but do not serve as the primary pathway from the supply. Similarly, capacitors and transformers have specific functions within electrical systems but do not directly represent the pathway from the electrical supply to the house wiring.
