Not from the point of view of safety. The plug fuse is there to protect the cord (only, not the product). But if the EUT is small and light, a 13A cord may be so mechanically assertive that the product can't be positioned easily and may even not stand on its feet properly, if the cord is twisted. A case of the 13 A tail wagging the 0.5 A dog. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Swine wave - a waveform whose spectrum is exceptionally difficult to calculate.
