We have several 2400 volt induction motors in our plant. There is a theory in the plant that there is a shock hazard if you touch a motor lead wile the motors is coasting down to a stop. Some of the motors supply big blowers and can take 15 minutes to stop.When ask about I said that there was nothing to it but i would ask. I also was told by the millwrights that it was unsafe for them to work on equipment wile we were megging it.
