Good information, Tom.  This is one reason why I replaced the excessively 
long #18 AWG line cords on my Alpha amps and replaced them with #10 AWG.

In addition to the line cords, I am using #10  between the shack and load 
center.  30-amp 4-pole twist lock plugs to a 30-amp breaker.

If the load center wasn't already conveniently on breakers, I would also 
bring out a shack sub-panel and use fuses rather than breakers.
