I don't want to setup to measure voltage at 60 Hz, but a quick ohmmeter measurement puts the DC resistance below 0.1 ohm.
If it was 0.1 ohm, then at 20 A the DC drop would be 2 V, and power dissipation would be 40 W. From a calculation of 40 W, that alone says the resistance is much lower than 0.1 ohm. AC impedance won't be much higher than DC resistance.
