(1) You must make sure the disconnecting means (such as on/off switches and circuit breakers) is marked to show when it is open and closed and what equipment it controls, unless located and arranged so the purpose is obvious.
(2) You must install the disconnecting means at a readily accessible location nearest the point of entrance of the service-entrance conductors.
(3) You must make sure the disconnecting means for each motor and appliance is marked, at the disconnecting means or overcurrent device, to show when the circuit is open and closed and what circuit it controls, unless located and arranged so the purpose is obvious.
(4) You must make sure each service, feeder and branch circuit is marked, at its disconnecting means or overcurrent device, to show when the circuit is open and closed and what circuit it controls, unless located and arranged so the purpose is obvious.
(5) You must make sure markings are durable and appropriate to the environment.
