Does the NEC allow for portable lockout devices, such as those manufactured by Panduit, to be used to lockout a circuit breaker in a panelboard? We have a number of these devices in use to prevent the shutting off of breakers that feed lights, outlets, etc. These devices fit over the circuit breaker (such as Square D I-Line or QO style) and allow for a safety lock to slide through it. Please let me know what the regulations and requirements are for these portable lockout devices. Thank you. GMEngineer
