Abstract
Electrical power conductor apparatus for earth boring using a rotary drilling rig and drilling string for mounting a bottom hole electrical motor to rotate a drill bit to form the borehole with electrical power from an electrical power source at the earth surface communicated to the electrical motor by conductor lines positioned in the bore of the drill string and having releasable supporting connectors to enable adding and removing of lengths of conductor lines as desired. The conductor apparatus includes electrical conductors having upper and lower plugs with the upper plug releasably securable with the drilling string and releasable by engagement with a fishing tool to remove the conductor from the drilling string.
