Switchgear busbar maintenance grounding
When performing maintenance on feeder cables or line-side equipment, operators first open the circuit breaker and disconnector, then close the earthing switch. This grounds the line side reliably. New Approaches for Maintenance Grounding in Medium-Voltage Switchgear by Joe Richard and David Mabius Executive summary Maintenance grounding has traditionally been performed by maintenance personnel working in close proximity to open switchgear. It effectively prevents electric shock incidents from accidental re-energization by an upstream. This section contains information on inspecting and performing preventive maintenance on HVL/cc Metal-Enclosed Switchgear. Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS-2011, or CSA Z462.
