Always verify the motor/equipment you're locking out is prevented from running! Coworkers and I were just dishing commissioning job horror stories where folks get too antsy to run their facility and start bumping motors while people are still working elsewhere.

Just because that breaker is labelled to run a specific motor, unless its been verified, it might be wired to the wrong motor, or the labelling is wrong or any other host of oversights.

Had a manager come in, and run his motor. The electrician who was elsewhere in the facility straddling a auger watched it suddenly spin beneath his feet because the lock he put on a breaker was not physically wired to that motor (had not yet been tested).

Lots of horror stories from that particular site. Always verify YOURSELF. Don't trust other people's word
