ABSTRACT: GR-347-CORE provides the functional performance requirements for telecommunications power cable products (14 AWG to 1,000 kcmil sizes) used to supply up to 600 volts ac/dc power to communications equipment in Central Office (CO) and outside plant (OSP) facilities.

This document combines all aspects of power cable product performance relevant to telecommunication applications and customized for the CO and OSP applications.

Issue 3 includes:

• Updating of cable designations (RHH, RHW, etc.) to harmonize with current industry practice and codes (NEC), and expanded to cover applications in wet environments
• Updated quality management system requirements and expanded to match with the latest trends in the telecommunications industry
• Revised conductor diameter requirements to match the current industry needs in terms of more stringent tolerances on copper conductor core dimensions to provide more uniform and improved performance in crimped connectors
• Revised mechanical requirements to clarify test procedures and supply guidance on specific tests including the bend resistance and the frictional abrasion tests as well as introduce new and improved test procedures
• Enhanced and clarified fire resistance requirements to meet users' and suppliers' needs.
