Hello,
I am trying to understand when temporary/external lockout devices are OK and when they are not and am having a hard time finding an answer. For example, when is it OK to use a circuit-breaker lockout device that is not attached permanently to the breaker? When does "The provisions for locking or adding a lock to the disconnecting means shall be installed at the switch or circuit breaker used as the disconnecting means and shall remain in place with or without the lock installed." apply? Is it required to have a permanently-affixed lockout device on all circuit breakers that need to be locked out at some point? Or are the above provisions limited to certain applications?
Thanks for any help or insight provided!
