Service Entrance Conductor
Definition and meaning of Service Entrance Conductor in real estate.
A service entrance conductor is the electrical wiring that connects the utility company's service drop or lateral wires to the home's main electrical panel or meter socket. It runs along or inside the building's structure to deliver power safely to the main service equipment.
In more detail
These wires represent the portion of the electrical service system that the homeowner is responsible for maintaining and repairing. They are typically housed inside a protective conduit or cable assembly to shield them from weather, moisture, and physical damage. During home purchases, inspectors examine these conductors to ensure they are undamaged, properly grounded, and rated for the home's electrical capacity.
If these wires are undersized, the home may not support modern electrical demands, which is a common issue in older properties. Upgrading these conductors requires a permit and must be performed by a licensed electrician to comply with national and local codes.

What size service entrance conductor do I need?
The wire gauge depends on the electrical service capacity of the home, with a two-hundred-amp service typically requiring larger copper or aluminum wires than a one-hundred-amp service.
Why would service entrance conductors need to be replaced?
They require replacement if they show signs of decay, cracking, water intrusion, or if the homeowner is upgrading the home's total electrical capacity.
