Looking for some input on how others verify you have a proper lock out? NFPA 70E states verify the equipment can not be restarted by means of a push button, selector switch... other electrical means. That approached work many years ago when we had simple 3 wire controls. Today , at least where I work we have DCS stops, Load controls interlocks, thermal cut out, flow, pressure... you name it we have interlocks for it. If we do a lock out and push the start button on the motor does not start, could or could not be a good lock out, could be held from starting via a interlock.
We talked in house about using a push to test pilot light at the start/stop station as indication that power has been removed? Costly to do that, so looking for any suggestions of insight on how others verify a proper lock out. As always you help and comments are greatly appreciated.
