NFPA 79:external power vs estop string
NFPA 79:external power vs estop string
(OP)
From NFPA 79, 13.2.4 requires that orange is to be used for conductors that do not de-energize when a disconnect is switched off. How does that reconcile with a production line that has multiple machines but only one central estop string. Do all of the estop conductors have to be orange in the various line components?
