    I have a single 20A circuit breaker for my garbage disposal, reading 122.9vac at the box, and ~114vac at the switch, whether the switch is connected or not.

    I realize that 114-126 is the accepted range for 120v systems, but my new Insinkerator Evolution is not even making a sound when I try to turn it on - and the power is making it to the unit, but only 114v.

    Maybe I'm TOTALLY wrong, but I'm testing the hot and the neutral. Other receptacles and switches give me 122-124 with hot and neutral. I had an electrician out here Monday and he did a more than thorough check, showing me 124 from the box all the way to the contacts on the Insinkerator.

    Is it possible that he was testing hot and ground? Because when I do that I get 123.5v.
