A fire that displaced two families last week and closed a Derry, N.H., restaurant, was most likely started by a loose electrical connection.
According to a report from The New Hampshire Union Leader, the blaze caused about $100,000 in damage to the Derry Restaurant & Pizza. Workers reported seeing sparks coming from the electrical panel in the basement of the building while they were unloading stock.
Fire investigators later disassembled the panelboard and determined that a short likely caused the blaze. It possibly was caused by a loose connection on a breaker that corroded over time and caught fire, a fire investigator said.
