[Amps] Dedicated 220AC Wiring for Amps..

[monty taylor]

This brings up a question I have.  I am using my pre-wired dryer outlet,
30 amp breaker, #10 wire; red, black and white.  It has only three
conductors and no ground wire, just; hot, hot, and neutral.  The house
is 10 years old and code approved.  For the amp, an AL1500, I wired per
the instruction manual for 220 Volts, hot, hot and neutral to the
ground/chassis connection.  Now, I want to RF/AC ground the chassis to a
different 8ft copper clad ground rod.  I read that you should never
connect neutral and ground together at any place other than the entry
panel as a difference in voltage potential could exist.   The #10 run to
the dryer outlet is about 30 feet.  My question: Should I ground the amp
to the new rod outside my shack or not?  I have been using the shack
with out any ground rods so far; only at the far end of all my coax runs
through lightning surge protectors.

A little wordy, but I hope I get some answers.
