Electrical work on a mislabeled control wire at the Dean Street Station caused a townwide power outage that lasted about 20 minutes, according to the Norwood Light Department.
"There are thousands of control wires that control breakers and meters and one of them was mislabeled," said Malcolm McDonald, Light Department superintendent.
Calls from residents and business owners reporting loss of electrical power began pouring in at 10:20 a.m., according to incident logs provided by the Norwood Police Department.
Police Department spokesman Kevin Grasso said that outages along Route 1 affected traffic lights. "There were no incidents and no serious calls resulting in this," he said.
McDonald said within 11 minutes 90 percent of the town's power was restored and seven minutes after that the entire town had power.
According to police incident logs, by 10:50 a.m. most of the town's traffic lights were operating.
