    Unless you own your own power plant, have access to Bill Gates' money, or a sure-fire way to counterfeit US currency, this would be my current top pick for Bad Idea of the Year.

    When I worked for a contractor, my techs would take the power for the shunt (if we used one) from the device being shutdown. If the power failed, no worries, because the equipment was off already.
