One does have to deal on occasion with questions from marketing and others…. I didn’t expect there would be any regulatory reason not to have power cords with different colors, other than possibly some obscure safety requirement for particular colors that I wasn’t aware of, hence my question. From the answers, it appears that there is no problem. Apparently colorized power cords are over the place and I just haven’t seen them. (Nope, I’m not color blind :=)
I know of course there are requirements for the wire markings inside the power cord, however, that was not the question I asked. Regards, George Stults From: Ronald R.

The intended usage of these power cords was for the audio industry when they rack mounted products and wanted to tell what cables were power cords behind an instrument rack. Also, a previous employer of mine had a tendency to change the color of their power cord sets about every 3 to 5 years. Flint gray, dove gray, and mint gray are but a few colors but who knows what color the industrial designers like these days. Probably black, because black is the most widely used color and is the most available. Also, cost of cord sets has nothing to do with color if you buy lots of them. Another argument about color has to do with out-of-sight, out-of-mind. Who cares what color a power cord is when its behind an instrument and hidden by furniture and other equipment. As a product safety professional I'm more concerned about consistent and reliable construction of the power cord, how it will be used, and making sure there is no excessive lead (Pb) residue in PVC jackets.

The cords you are speaking about are typically molded-on with a plug and a molded-on connector to mate with appliance inlet. For each country, you will need to supply a cord set which is approved for the country's usage. Therefore, colors do not make a difference since you will be purchasing cord sets with certifications for that countries power system. Why worry about colors? Peter George Stults <[email protected]> wrote: Hello Group, I have a question regarding the Colors that detachable equipment power cords (type used for ITE equipment, AC Mains 220/110VAC) are available in. I have only ever seen Black and Grey power cords. Is there a regulatory or other practical reason (in USA or Europe or Worldwide) that they could not, or should not, be made for example with Blue, or Yellow, or Red pigmented plastics? (or does someone already manufacture such power cords?) Thanks in advance.
