Duke Energy engineers have found damage to an underground cable that likely caused an electrical fault that blew the covers off some downtown manholes Tuesday night and damaged wires and equipment.
It happened about 9:45 p.m. Tuesday, as a thunderstorm was over the city, but Duke spokeswoman Meredith Archie said workers did not know Wednesday whether that was a factor.
Archie said it’s not clear what caused the damage to the cable, which led to an electrical flash that dislodged the manhole covers. She said two business customers lost power and that a window in a building had been broken in the incident.
Archie said power should be restored to the businesses Wednesday evening and that Market Street, the focal point of the repair work, should reopen then.
