I assume that part of the reason for the &quot;thick copper cables&quot; is to bring the resistance as low as possible, like, under an ohm for a few thousand feet of 2 gauge wire.<p>Which will still be thousands of volts, but it sounds like it&#x27;s pulsed thing as well, and they would certainly disable it if they&#x27;re not in a dive or otherwise trying to be stealthy.
