[Amps] 220VOLT LINE...Redux and ??

>Dear Mike,
>
>The Henry 2KD at 220vac input is said to consume 15 amps, tops.
>The #10AWG feed from your distribution panel, at 50 feet, is plenty
>of circular mils to not heat up when your key is down.
>
>The issue you mention of running a separate neutral outside of the 
>confines of your normal feed is a bad practice, though, because
>of the double-insulation requirement for Romex and because wiring that
>is not double-insulated normally runs in conduit, which provides the
>extra layer of protection.
>
>You've gone and spent $2K on a nice amplifier. Why not treat yourself
>to some nice wiring. Even though it will be in the wall will you not sleep 
>more soundly knowing your house wiring has that layer of protection it's 
>taken 100 years of electrical experience to afford you?
>
>If you're going to run the 10/3 with ground, make sure you install the 
>right 4-prong outlet. At the PDSC, you might even consider a GFCI type
>breaker.

**  GFI breakers have a reputation for RF detection, so some ferrite 
beads and bypass caps may be needed.  To pass NEC, the bypass caps must 
be 1400VDC-rated.    If you want your station to be fully  NEC-compliant, 
the smallest wire gauge allowed for radio antennas is 14-gauge.
