[Elecraft] Breakers for KPA1500

[Clay Autery]

I put a sub-panel in the shack....  I ran 4 x 6GA stranded THWN-2 in two 
sets of twisted pairs inside a steel flex conduit from the main box to 
the sub box.  Running dual 60 Amp (tied) breakers at the box to catch 
both hots for 240 VAC.  The hots are paired, and the Neutral and ground 
are paired.

The sub-panel is broken out into 2 x 240 @ 15amps, 2 x 240 @ 20amps, and 
8 x 120 @ 20 amp breakers.  Each breaker feeds a single plug on each of 
the 6 x 120 x 20amp duplexes, and 1 x 240 @ 15 and 20 amp duplexes 
respectively.  I can turn EACH receptacle off at the sub-panel.  From 
the panel to the 6-ganged (in steel gang boxes), I also ran 4 x 10GA 
THWN-2 paired the same also in steel flex conduit.

Currently, I have a single 220 x 15 amp and 220 x 20 amp receptacle 
free. ALL 120 receptacles are in use (no bus bars).
Never thought they'd fill up that fast.

No where near maxing out ANY of the breakers or the master 60amp........ 
yet.

My solution MAY be overkill for your install, but the lesson is...

Don't build for today.... build for TOMORROW and build ONCE.

They used new metal clad 4  by 12 gauge from the service box to the outlet with 20 amp breakers on each side.  I personally make no warranty, but they assured me it would be both safe and more than sufficient.
