Blown Fuses...

I got up on the roof and opened up the electrical panel. Two of three phases were gone. I checked the other three units, same problem.


The building was undergoing a renovation. I spoke to the electrician on site and found out there was a few sparks that came from the circuit breaker when they ran their fish tape through it. I checked the breaker supply and found two blown fuses. I replaced them and left a few spares for future use...
