If the Centurion has a 4 wire power cord:
  I will tie the chassis ground to the ground in the feed, the amp's bond
to the feed's neutral and the 110V single phase lines to the amp's
black/red.

The idea being to use the neutral as a means to return fault current and
the ground to chassis ground.



If the Centurion only has 3 wires in its power cord:
  I will tie the 110V lines to the amp's black/red and tie the amp's
ground to neutral and run a chassis ground to the ground and also to my
shack ground (copper braid to a ground rod outside).


Is there an issue with tying my breaker panel ground to my shack's ground?


thanks,
Jason
