A system and apparatus for providing a temporary electrical bonding/grounding connection between a first conductive member and a second conductive member. The apparatus includes an electrically conductive cable having first and second ends. At least one magnet assembly is provided for mounting to the first conductive member. The at least one magnet assembly has multiple arcuate surfaces of different radiuses of curvature, with respective surfaces of the multiple arcuate surfaces being configured to properly mount to a respective arcuate surface of the first conductive member. A conductive coupling is provided on the at least one magnet assembly. The conductive coupling is configured to be electrically coupled to the first end of the cable. The second end of the cable is configured to be detachably and electrically coupled to the second conductive member.
