[Elecraft] KPA500 AC power

[Don Wilhelm]

Tom,

If you have a dedicated 120 volt receptacle in the shack, that would be 
OK to use, but if it is shared with other receptacles in the house, you 
will find blinking lights with CW or SSB speech.

If you have to run new wiring to the shack, run 240 volts and if you run 
a 4 wire system, it can be split out to 2 120 volt receptacles that you 
can use exclusively in the hamshack.  Your electrician will know how to 
split it out.  Ask him to use #12 wire, or better yet #10 for a lower 
voltage drop from the breaker box.  Many receptacles are wired with #14 
wire (except for kitchen circuits which must be #12 wire according to 
code).  If you have an older house, definitely get dedicated wiring to 
the shack - who knows what older wiring may entail, it was wired only to 
the codes at the time of construction.

73,
