Bill,
The simplest way to do it is to remember that the fuse protects the wire; not the device. Size the wire to handle the continuous load with acceptable voltage drop, and the size the fuse to protect the wire. (A whole fuse panel is about the price of one a/c circuit breaker.)
There's a chart in Bob's book showing how to size wire for load & length.
