A portable locking means doesn't meet requirements [NEC 422.31(B)]. Does this circuit breaker lockout fulfill code requirements?


This circuit breaker lockout is designed for locking out machinery or isolating hazardous energy during repair or maintenance according to OSHA 1910.147. It was not designed to specifically comply with NEC 422.31(B), nor can we validate whether it meets the requirements.
