after setting up a new 8" Can Fan in our attic, we decided to turn the setup on for a test drive before getting out and leaving things. Somehow, the motor arc'ed to the ducting attached to the fan, creating a monstrous spark that toasted nearly a foot of ducting in one big WOOOOF! My roommate was nearly blown backwards and if it had stayed plugged in for another 5 seconds it would have sparked the insulation and burned the house down.

Yay for test drives! There was so much amperage going through the cord that I had to brace myself to pull the cord from the socket. It fried the cord, the fan, the ducting, and the outlet. Then it tripped the breaker.

Fun stuff.
