SEATTLE (AP) — Seattle City Light says three of its employees were injured as they tried to install a ground rod at a Seattle substation.
The Wednesday afternoon accident triggered a power outage that affected nearly 10,000 customers. Power has since been restored.
Utility officials say the crew’s equipment caused an electric arc from an underground power line.
Seattle Fire Department spokesman Kyle Moore says one man in his 50s tumbled 20 feet and suffered a concussion, a 63-year-old man suffered thermal burns and a man in his 20s was cut and bruised. Moore says all three were taken to Harborview Medical Center.
