National Grid officials ruled out natural gas as the cause for manhole explosions in Melrose Friday evening, and said there was an “underground cable fault’’ that crews were working to repair Saturday, according to a statement issued by the company.
The incident happened at about 8 p.m. Friday on Essex Street, between West Emerson and Vine streets. No injuries were reported.
In a statement that was posted on the city’s website Saturday afternoon, National Grid officials said they had to take a section of cable out of service for four houses, and replace it.
The endeavor was expected to take four to six hours.
Debris from the blast blew out a number of home’s windows, and a sidewalk was damaged. No one lost power, officials said.
National Grid officials are scheduled to meet with the city’s mayor on Monday.
