Communications Line - Underground

How it Works

Communication wiring connects your home communication devices with the outside world. This includes telephone, internet, security (closed circuit) television, computer networking and TV cable wire. These wires usually run underground from your utility supplier’s main connection box - usually located near the street - to your home.

In most cases, underground communications wiring is low voltage, so it does not require a protective conduit. However, proper wiring has a special rating for underground service and it should be buried low enough to prevent damage from freezing and thawing cycles. In some cases, mandatory building codes and standards may apply.

What Can Go Wrong?

Underground communications wiring is sometimes damaged during excavation. Know where your wiring is located before any digging projects and call the “Call Before You Dig” hotline to mark out any previously installed wiring. Problems also arise when homeowners use wiring that is not rated for underground use.
