Method for selecting power from two or more circuits

1. A method for the selection of power from two or more different circuits, said method comprising the steps of:

providing a chassis with an electrical chassis receptacle for providing power from said two or more different circuits that are electrically connectable to said chassis for the supply of said power thereto;

providing a duplex element having at least one electrical duplex receptacle, said duplex element additionally having first conductor means therein for electrical connection to said chassis receptacle, said duplex element being connectable to said chassis in different orientations for selection of power from one of said two or more different circuits;

providing said chassis with a plate member for engaging said duplex element, said plate member being slidably movable in relation to said chassis for alternately moving said duplex receptacle into and out of electrical contact with said electrical chassis receptacle;

choosing one of said two or more different circuits to which to electrically connect to said at least one duplex receptacle by choosing an orientation in which said duplex element is to engage said chassis; and

engaging said duplex element with said plate member in said orientation and sliding said plate member and duplex element towards said electrical chassis receptacle to electrically couple said at least one electrical duplex element with said electrical chassis receptacle, thereby electrically connecting said at least one electrical duplex receptacle with said chosen one of said two or more different circuits.

2. The method of claim 1 , wherein said electrical chassis receptacle comprises a plurality of connection points therein for selection of power from one of said two or more different circuits, and wherein electrical coupling of said duplex element with said electrical chassis receptacle includes electrically connecting said first conductor means with at least one connection point.

3. The method of claim 2 , wherein said duplex element comprises first and second ends, said first conductor means extending between both of said first and second ends, said first and second ends being alternately releasably connectable to said electrical chassis receptacle for placing said first conductor means in electrical contact with at least one different connection point in said electrical chassis receptacle.

4. The method of claim 3 , wherein the method further comprises positioning a non-conductive cover at said second end of said duplex element to obstruct exterior access to said first conductor means.

5. The method of claim 1 , wherein said duplex element comprises a housing defining at least a first surface having at least one electrical duplex receptacle and a second surface having at least one electrical duplex receptacle; and wherein said duplex element can alternately engage said plate member of said chassis in a first orientation to expose said first surface or in a second orientation to expose said second surface, said first and second orientations allowing for electrical connection of said duplex element to different circuits of said two or more circuits.

6. The method of claim 1 , wherein said chassis comprises first and second ends with second electrical conductor means extending therebetween, said second conductor means comprising a pre-determined number of electrical conductors, respective ones of said electrical conductors being electrically connected to respective ones of connection points in said chassis receptacle;

wherein said first and second ends of said chassis are respectively connectable to said second or first ends of another of said chassis for a series electrical connection therewith.
