Abstract: A support system for conductor wires within a building having horizontally spaced apart building structural points includes a support line having two support line ends, an anchoring mechanism anchoring the support line ends to the spaced apart building structural points, and at least one hanger suspended from the support line, the at least one hanger having an engaging structure for engaging and supporting the conductor wire at a given location along the conductor wire.

Abstract: Safety power outlet connected to a plurality of power lines, including a hot line, and arranged to receive the prongs of a matching multipronged power plug has a receive terminal connected to each power line. The receive terminal is arranged to receive a corresponding prong of the power plug which upon insertion into the terminal operates a switch associated with each terminal. All switches are connected in series, and upon complete insertion of all the prongs, the series connected switches complete a power connection from the hot line to its respective prong, which in turn provides power to the external circuit connected to the power plug.

Abstract: Safety power outlet connected to a plurality of power lines and arranged to receive the prongs of a matching multi-pronged power plug has a receive terminal connected to each power line. The receive terminal is arranged to receive a corresponding prong of the power plug which upon insertion into the terminal operates a switch associated with each terminal. All switches are connected in series, and upon complete insertion of all the prongs, the series connected switches generate a connect signal which activates a power connection device that applies power to all high potential prongs, which in turn activates the external circuit connected to the power plug.
