Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 355 words
A power outlet device removably mountable in an electric power distribution panel, said device including a ground fault detector-interrupter first means, a receptacle means, and an elongated unitary generally block-like insulating housing means including a first housing portion for said first means and a second housing portion for said receptacle means; said second housing portion including a front section, a rear section and retaining means securing said sections together and securing said first and second housing portions together; said first means including a line terminal at one end of said first housing portion operatively engaging a distribution panel hot conductor positioned at the rear of said first housing portion; said receptacle means including hot load contact means, grounding contact means, line neutral contact means and load neutral contact means; first conductor means within said housing means extending through said first means and connecting said hot load contact means to said line terminal; said hot load contact means being operatively engaged by plug prong means extending through opening means in the front of said second housing poriton; said grounding contact means having a first portion operatively engaged by plug prong means extending through opening means in the front of said second housing portion and having a second portion engaged with a panel ground conductor at the rear of said device; said load neutral contact means being operatively engaged by Plug prong means extending to opening means in the front of said second housing portion; said hot load and load neutral contact means having substantially identical constructions; a block-like insulating member disposed within said second housing portion between said front and rear sections; said grounding contact means extending through said member with said first and second portions of said grounding contact means projecting from said member at its front and rear, respectively; said line neutral contact means being maintained by said member at a position both insulated from said load neutral contact means and operatively engaged with a panel neutral conductor at the rear of said device; second conductive means within said housing extending through said first means and connecting said line and load neutral contact means.
Claim 2
Dependent Claim 355 words
A power outlet device removably mountable in an electric power distribution panel, said device including a ground fault detector-interrupter first means, a receptacle means, and an elongated unitary generally block-like insulating housing means including a first housing portion for said first means and a second housing portion for said receptacle means; said second housing portion including a front section, a rear section and retaining means securing said sections together and securing said first and second housing portions together; said first means including a line terminal at one end of said first housing portion operatively engaging a distribution panel hot conductor positioned at the rear of said first housing portion; said receptacle means including hot load contact means, grounding contact means, line neutral contact means and load neutral contact means; first conductor means within said housing means extending through said first means and connecting said hot load contact means to said line terminal; said hot load contact means being operatively engaged by plug prong means extending through opening means in the front of said second housing poriton; said grounding contact means having a first portion operatively engaged by plug prong means extending through opening means in the front of said second housing portion and having a second portion engaged with a panel ground conductor at the rear of said device; said load neutral contact means being operatively engaged by Plug prong means extending to opening means in the front of said second housing portion; said hot load and load neutral contact means having substantially identical constructions; a block-like insulating member disposed within said second housing portion between said front and rear sections; said grounding contact means extending through said member with said first and second portions of said grounding contact means projecting from said member at its front and rear, respectively; said line neutral contact means being maintained by said member at a position both insulated from said load neutral contact means and operatively engaged with a panel neutral conductor at the rear of said device; second conductive means within said housing extending through said first means and connecting said line and load neutral contact means.
Claim 3
Dependent Claim 42 words
A power outlet device as set forth in claim 1 in which the retaining means includes a bracket secured to one side of said first housing portion and operatively engaged with a sidewall of an extending section of said second housing portion.
Claim 4
Dependent Claim 25 words
A power outlet device as set forth in claim 2 in which a part of the bracket is sandwiched between said front and rear sections.
Claim 5
Dependent Claim 58 words
A power outlet device as set forth in claim 1 in which the first means includes cooperating contact means constituting a portion of the first conductor means; and an operating handle operatively connected to said contact means for selectively opening and closing the latter; said handle being accessible at the front of said housing means for manual operation.
Claim 6
Dependent Claim 35 words
A power outlet device as set forth in claim 1 in which the line terminal, the second portion of the grounding contact means and the line neutral contact means each constitutes a plug-in type terminal.
Claim 7
Dependent Claim 49 words
A power outlet device as set forth in claim 1 in which said line terminal, said second portion of the grounding contact means and said line neutral contact means each constituting a plug-in type terminal; said receptacle means including first and second plug-prong receiving receptacles connected in electrical parallel.
