lighting cables for CNC

Hi,

As a greenhorn, when I first stared wiring up motor cables, I took
the trouble to look for cables with hefty cross-section, ended up
using what they called automobile cable or something. But these are
hard to solder onto the connector pins.

I had a look at the Nema23 2amp wires and they were pretty wimpy, and
it looks like they have about the same cross-section as those cables
for domestic lights (220VAC). Like to fish for comments on the
suitability of these lighting cables for motor usage.

Thanks in advance

Andrew
