Service Entrance Cable

Service entrance cable is specifically designed to handle the high voltage and current levels required for supplying electricity to the premises.

Construction

Voltage:
0.6/1kV

Conductor:
Copper, AAC, AAAC, Copper clad aluminum

Insulated:
XLPE/PVC/PE

Out Sheath:
PE/PVC

Application

Service entrance cables are typically installed underground or overhead, connecting the electric meter on the exterior of the building to the main electrical panel or load center inside.

They serve as the primary connection point between the utility’s power lines and the electrical system of the building.

Feature

It is constructed with multiple conductors, including phase conductors (usually black, red, or blue insulated wires), a neutral conductor (typically white or gray insulated wire), and sometimes a bare copper or green-insulated grounding conductor.

The conductors are typically made of copper or aluminum, with copper being more common due to its superior conductivity.

Standard

IECA Standard, NFC Standard.
