[Elecraft] Voltage drop in DC Power to K3

[Charlie T]

>From the wire tables, I think you'll find that doubling the number of wires
will result in an equivalent of one cable 3 wire sizes larger.

That is, two #18 wires equals one #15 ( and yes, I KNOW there isn't any #15
wire easily available).
Likewise, two #12 wires is the same as one #9.
So, from this, the hassle of using two #12 wires is only slightly better
than one #10, but not quite as good as one #8.

Obviously, every installation may be unique, so use the largest you're
comfortable with.

Heatshrink tubing will cover the unsightly chop job.

Yep.

And I've also used W1ZR's solution of two of the same size cables in
parallel.
