I have a general question, I hope someone here knows the history on it.

Is there is a length restriction on power cords for instruments?  I am not 
referring to extension cords.  But either hard connected cord, or the the 
removeable C13/C14 style cords?

If so, what is it, and why is it?  Discounting the EMC issues, what, if any, is 
the safety issue with a long power cord?  Which standards spell out this 
length?  What testing or rationale supports this?


Many thanks,

Regards,

Gary
