I am in the process of making some home brew power cables and need to choose between a cable capable of carrying 10A and a cable capable of carrying 16A. (Its the Supra Lo-Rad stuff). Denon advertise my AVR-2805 amp as having a power consumption of 290W. Panasonic publish the same figure for my PW7 plasma. Is it possible to calculate a corresponding ampage figure from that? Basically, I just need to know if 10A cable will do, or if I need the 16A stuff. Thanks, folks.
