[Elecraft] [OT] Zip Wire Misrepresentation?

[Don Wilhelm]

Ronnie,

It "all depends"

I use 12 gauge myself, but the runs are less than 6 feet.
For longer power cables, I would use 10 gauge or larger.

#10 is .000999 ohms per foot
#12 is .001588 ohms per foot.

For 12 feet of conductor (yes, you have to count the resistance both 
directions) - at 18 amps current draw, the #10 will produce a .22 volt 
drop while #12 will produce a .34 volt drop.
So take your pick, either increase your power supply voltage to 
compensate or go with the larger wire.
