There was a fire in my building. The two end tenants experienced an electrical fire. Although it was not serious. The electrical problem was caught by a manager before it got out of hand. Very close call. It was within a minute or two of being too late because he was on his way out for home.
The cause.
A contractor installed underground wiring for cable access to the building. Even though all the other underground wires and plumbing were marked they still managed to nick the power feeds. Possible miss mapped lines???...
dual quad 3 phase feeds.
Somehow the wire nick caused a leak to neutral that caused a reverse feed back into the building. Inside one circuit on each end of the building overloaded on the bare copper ground line. Of course it lit up and burned. Of course the wiring was on wood. Of course the only reason the fire did not get fully involved was because one person on his way out saw smoke.
This could have been a disaster. But it will still cost the contractor thousands to get this all fixed. All the wiring in the building is being audited. All the burned wiring has to be replaced. The quad four 3 phase underground feed has to be replaced. The smoke damage has to be cleaned.
I was lucky in that just my floors are tracked up from the fire department coming through to look for possible fire and a few ceiling tiles will need to be replaced.
Be sure to call Miss Dig and get the clearances. Otherwise you could be in for some very bad karma.
