(E) Controlled Receptacle Marking. All nonlocking-type, 125-volt, 15- and 20-ampere receptacles that are controlled by an automatic control device or incorporate control features that remove power from the outlet for the purpose of energy management or building automation shall be marked with the symbol shown below placed on the controlled receptacle outlet where visible after installation or have clearly legible marking in letters not less than 6 mm (? in.) high reading ?Controlled?. The label shall comply with 110.21(B).

[Icon is a vertical line with its lower end at the center of a broken circle. It is the "standard" European on/off symbol"]

5 Statement of Problem and Substantiation.

Allow these receptacles to be marked with text for both retrofit work and new work when specially marked receptacles are not available and the electrician does not have stickers with the designated icon and lacks artistic skills.

Indeed currently produced ?controlled? receptacles are marked ?CONTROLLED?. For example see ?Leviton vizia rf+? (a random example).

Allow these receptacles to be marked with text for both retrofit work and new work when specially marked receptacles are not available and the electrician does not have stickers with the designated icon and lacks artistic skills.

Unlike the other two receptacles which are marked with icons (isolated ground and hospital grade) a controlled receptacle may be that merely by virtue of the branch circuit that feeds it, not by any mechanical property of the receptacle itself. (Yes, I know about X-10 and its like.)

I am not sure this is necessary in most cases I deal with. What if 1/2 the device is switched and feed from the same breaker? It would make sense if the receptacle that is controlled entirely by an automatic system but not where 1/2 of the outlet on the same circuit is concerned.

I can also see if the controlled half is controlled by a different circuit then the non controlled half.
