In what appears to be the first salvo of New Jersey litigation over the power losses caused by Hurricane Sandy, the state’s second-largest electric company has been hit with a putative class action.

The suit, filed Wednesday in Hunterdon County Superior Court, alleges that Jersey Central Power & Light, and its corporate parent, First Energy Corp. of Akron, Ohio, breached contracts with customers by ceasing to provide service for seven days or more after the massive Oct. 29 storm devastated large parts of the state.
