MOUNT CARMEL - Approximately 4,000 borough residents were without power Saturday when a circuit breaker opened, causing a problem on the line.

PPL spokesman Rich Beasley said crews were dispatched shortly after the 8:10 a.m. incident and they gradually restored power to all customers by 9 a.m.

"We got back and we're trying to find what caused it. We're still looking into that," he said Saturday evening.

During the outage, Mount Carmel Borough Police advised citizens via Facebook posts that the street department would be placing stop signs at the red light intersections of Fifth and Market streets, Third and Market streets and Avenue and Market streets.

"Use caution at intersections where traffic signals are in place," police said. "Residents are reminded that if a traffic signal is not functioning properly you are to act as it is a four way stop and stop until it is safe to proceed."

Fire police were not needed during the outage, said Mayor Philip "Bing" Cimino.

Police Chief Todd Owens could not be reached for further comment.
