ABSTRACT:
A hot line load pick-up hand tool for use in electrical transmission and distribution systems has improved electrical conductivity and is capable of temporarily picking up and safely carrying high voltages being transmitted by energized main and branch feeder cables and transferring current therefrom to non-energized distribution lines prior to and during installation of permanent current transfer connections, all without any likelihood of damage to the cables or appreciable danger to workmen. Trip mechanism for closing the circuit through the tool after installation can only be reset prior to being placed in use, and the tool is inherently incapable of permitting breaking of the circuit while it is in place clamped to the main line. The entire tool is easily and quickly disassembled for inspection and cleaning of all its component parts.
