ASTM F2249 outlines the Standard Specification for In-Service Test Methods for Temporary Grounding Jumper Assemblies Used on De-Energized Electric Power Lines and Equipment

This standard specifies the requirements for the in-service inspection and electrical testing of temporary grounding jumper assemblies. These critical safety devices are used to establish a protective ground on de-energized electrical lines and equipment, safeguarding workers from accidental re-energization or induced voltages.

The standard details the necessary procedures for both visual inspection and electrical testing of the complete grounding assembly, including its flexible cables, ferrules, clamps, and connectors. It outlines the criteria for passing the tests and provides guidance on when an assembly must be removed from service. Adherence to ASTM F2249 is essential for ensuring the continued reliability and effectiveness of temporary protective grounds, a foundational component of electrical safety protocols.
