The resistance is not the problem, it is the small surface area making=20
the connection on both ends. The clamps on most cables have very small=20
contact area with the terminals. It would not surprise me if the contact=20
area was equal to that of a 10AWG wire. The resistance may read as 0 but=20
that will change when the metal begins to heat up from a lack of being=20
able to handle the high currents. It is like trying to power a home=20
using a needle at the end of the service wire and expecting all 200 amps=20
to flow across the needles contact point.
