STATE HOUSE, BOSTON - A "failed joint" in a feeder cable caused last week's power outage that upended the morning commute on three of the MBTA's four subway lines, officials said Wednesday, somewhat contradicting the T's earlier suggestion that its own infrastructure did not appear to be the problem.

Six days after the incident that prompted major delays on the Blue, Green and Orange Lines, the MBTA said its power department determined that a joint in the roughly seven-mile-long feeder cable was to blame.

"The MBTA is working diligently to address a power infrastructure issue that caused a recent disruption," T spokesperson Joe Pesaturo said in a statement. "Teams have pinpointed the cause -- a failed joint in a feeder cable located underground, only accessible by manhole -- and are replacing the damaged cable section. By leveraging backup systems utilizing energy from other parts of the power grid, service has continued safely through alternate feeder cables in the interim."
