Brief Description of Incident:
Using UG equipment, we were pulling in 3 phases of primary underground, termination to termination, no boxes in between. Pulled wire all the way through conduit and used digger boom to pull enough wire out of conduit for termination.
Roller was approximately 40′ in the air when the cable on the puller broke at the crimp end by the swivel and the wire fell to the ground. No equipment damage and no one was injured. Lesson learned was inspect cable ends for wear or damage.
Contributing factors: departure from routine, overconfidence/complacency, unexpected equipment conditions
