I am an electrical novice.

 

  • In and industrial setting, is it required by NFPA 70/70E to lockout a 120v standard breaker (like a household breaker), where the breaker has not been designed to take a lock?
  • Is a tagout device acceptable for standard 120v breakers?
  • Does it matter if the equipment was designed pre- or post-1990?
