warning
The thick cable is rated for 8 amps, but, be pre-warned
that is VERY difficult to get a good termination, as the
conductors are very small, and the insulation is very
thick and stiff. (calm down, you guys).
Seriously, the only worse cable I've worked with is
Genius cable.
If I had it to do over, I'd use the 4AMP cable, and
be done with it. Much nicer.
