[R-390] R390 power cord

[Dan Merz]

Hi,   simple questions regarding power cords.  I'm in the habit of acquiring
the pc-type power cords and cutting the female end off and using them for
various radio projects.  I have a 10 ft one that I'm going to use for the
R390.  It's marked 3/18 (18 ga. wire I assume and that's what it looks
like).  It has three covered, stranded wires including a green ground and
also has a fourth uncovered stranded wire that is under the metal foil
shielding cover, and all are sheathed in the oute plastic cover.  First
question:  is this wire size big enough?  It would seem so to me based on 2
to 3 amps.  Second question:  Should I connect both the covered green wire
and the uncovered wire to the radio ground at the radio?  They are both
connected to the ground on the three terminal male plug.  I assume the
purpose of the uncovered ground wire has to do with contact to the metal
sheathing (shield) around all the wires.  Dan.
