    Thank You Joe for this Very Important Warning.
    Like Joe says, Take the time to turn the circuit OFF and then TEST the circuit. I too have had similar experiences of finding an energized circuit that should have been OFF, and the condition could only be discovered by double checking and using a voltage tester. Make sure you have one and make sure you always use it.

    I used to be a refinery maintenance sparky. Got a ticket to replace a pump motor, went to the starter and turned off the breaker, and as per procedure took the time to open the explosion proof enclosure (about 15 minutes of removing bolts)put my meter across the load side of the breaker and found all three phases of the breaker welded closed. Being activated by a float switch, this could have been very unpleasant. It was only a 480v. circuit, but. Always, always, check. Even if it’s inconvenient, time consuming, or a “long walk”, open that panel, box, switchboard, and check at the source, it’ll make your day better.
