FAQ

What is CU Single Conductor USE?

CU Single Conductor USE is a 600V copper underground service entrance cable designed for underground service, feeder, utility, and electrical distribution applications.

What does USE mean?

USE stands for Underground Service Entrance. It identifies a cable construction intended for approved underground service entrance applications.

What type of conductor is used?

The product uses annealed copper conductors, available in solid or stranded configurations depending on conductor size.

Can CU Single Conductor USE be directly buried?

Yes, USE-type cable may be suitable for direct burial where the complete cable construction is approved and the installation complies with applicable electrical code and project requirements.

Can it be used in wet locations?

Yes. USE-type constructions are intended for underground and wet-location applications when manufactured and marked accordingly.

What is the voltage rating?

CU Single Conductor USE is designed for 600V applications.

What is the difference between USE and USE-2?

USE and USE-2 are related underground service entrance designations, but their exact temperature ratings, insulation systems, certification, and permitted applications can differ. The applicable product marking and governing standard should be checked for the intended installation.

Can CU USE be used above ground?

USE cable has specific application limitations. Above-ground use should only be made where the complete cable construction is specifically permitted and marked for that application. For general building wiring, a more appropriate building-wire designation may be required.

What conductor sizes are available?

Typical sizes range from 14 AWG through 1000 kcmil, with other sizes available according to project requirements.

Can custom constructions be supplied?

Yes. Conductor size, stranding, insulation color, marking, production length, and packaging can be customized subject to technical and certification requirements.
