I had a similar problem last friday night. 16 inch water main broken, 4 hours until it was shut off. about 500,00 gallons of muddy, sandy water through 600 amp service. Customer refused to let me shut them down (car dealership, have to sell those cars!!). I called the fire dept, who called city inspector. Immed. red tagged. Going back tonight to clean out the service and repair. Richard
