I was removing a Jacuzzi and the homeowner turned off all the breakers for the house (even though I only needed one turned off). I don't know whether she flipped the master switch or the subsidiary switches first but she did both. Later we turned everything on but the jacuzzi breakers. I was fine working outside with my reciprocating saw plugged into the house. I remove the special secondary fuse then I cut the jacuzzi wires, put plastic hats on the ends and wrap them in tape.
Later she finds that most of the plugs and lights in the house no longer work. What happened?
