The standard length of high- end power cords is usually 5 feet. If you need only 3 feet, then that's what I would buy. It will save you a few dollars and you won't have to loop or route the excess cord. Of course, if you want to use it somewhere else, in the future, it might be too short. Something to think about.
Power cords: does length matter?
This is a serious question, however if you don’t believe that anything about power cords matter, and you feel the need to make a joke out of the question, feel free.
Anyway: I have noted that all the stock power cords that have been provided by the manufacturers for my equipment are about six feet long. After looking at various aftermarket power cords on the internet, I note that they can be ordered in various lengths from one meter on up.
I would think that the shortest possible power cord in any given application would be desirable (meaning one meter if it would work), but I find that a lot of notions I had about things like this are often wrong (such as what I very recently posted on misc about manually tripping breakers to protect components). So am I also mistaken about selecting lengths of power cords?
TIA for any and all legitimate consideration and answers to this question, and to all others, enjoy the laughs.
