Abstract
Abstract A very flexible electric service panel for temporary hookups is constructed to receive plug-in circuit breakers for direct wiring, as well as four prong receptacle type plug-in power outlet fittings for making cord set connections. The power outlet fitting is constructed by utilizing a hook-like member to mechanically hold a subassembly and a receptacle together as a unitary structure. The subassembly consists of two single pole circuit breakers stacked side by side. The receptacle is adjacent to the load end of the subassembly and electrically connected to the load terminals of the breakers. Plug-in type neutral and grounding connectors at the rear of the receptacle engage forwardly extending legs of neutral and ground busses in the service panel, as plug-in line terminals of the breakers engage energized stabs in the service panel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
148 words
An electric panel including an enclosure and within said enclosure an elongated neutral bus, an elonaged grounding bus, and conductor means defining hot contact points; within said enclosure, said contact points being electrically insulated from said buses said buses being transversely spaced and parallel to each other with said contact points positioned to one side of said buses; said conductor means and said buses being operatively positioned so that said contact points are engageable by line terminals of receptacLe type power outlet fittings having plug-in type neutral and ground terminals engageable with the neutral and ground buses, respectively; one of said buses being positioned between the other of said buses and said contact points; each of the buses being generally of L-shaped cross-section with a forwardly extending leg thereof engageable by plug-in type terminals of receptacle type power outlet fittings having at least three prong engaging contact elements.
Claim 2
Dependent Claim
148 words
An electric panel including an enclosure and within said enclosure an elongated neutral bus, an elonaged grounding bus, and conductor means defining hot contact points; within said enclosure, said contact points being electrically insulated from said buses said buses being transversely spaced and parallel to each other with said contact points positioned to one side of said buses; said conductor means and said buses being operatively positioned so that said contact points are engageable by line terminals of receptacLe type power outlet fittings having plug-in type neutral and ground terminals engageable with the neutral and ground buses, respectively; one of said buses being positioned between the other of said buses and said contact points; each of the buses being generally of L-shaped cross-section with a forwardly extending leg thereof engageable by plug-in type terminals of receptacle type power outlet fittings having at least three prong engaging contact elements.
Claim 3
Dependent Claim
30 words
An electric panel as set forth in claim 1 in which the hot contact points are disposed in a row parallel to and transversely spaced with respect to said buses.
Claim 4
Dependent Claim
33 words
An electric panel as set forth in claim 2 in which the hot contact points are alternately phased and are engageable by plug-in type line terminals of a receptacle type power outlet fitting.
Claim 5
Dependent Claim
51 words
An electric panel as set forth in claim 3 including a mounting ledge within said enclosure extending parallel to said buses and positioned between said hot contact points and said buses; said mounting ledge having a forward surface provided with securing formations for mechanical securement of receptacle type power outlet fittings.
Claim 6
Dependent Claim
51 words
An electric panel as set forth in claim 1 including a mounting ledge within said enclosure extending parallel to said buses and positioned between said hot contact points and said buses; said mounting ledge having a forward surface provided with securing formations for mechanical securement of receptacle type power outlet fittings.
Claim 7
Dependent Claim
37 words
An electric panel as set forth in claim 5 including a meter socket positioned on the side of said contact points remote from said mounting ledge; said meter socket having terminals electrically connected to said conductor elements.
Claim 8
Dependent Claim
51 words
An electric panel as set forth in claim 5 in which the mounting ledge is provided with first and second forwardly extending mounting hooks for mechanically engaging a circuit breaker whose width spans at least four consecutive ones of said contact points said mounting hooks being positioned between said securing formations.
Claim 9
Dependent Claim
55 words
An electric panel as set forth in claim 7 in which the mounting hooks are spaced apart by a distance sufficient to permit a receptacle type power outlet fitting for a plug having at least three prongs, to be secured to the forward surface of said mounting ledge in a position between said mounting hooks.
Claim 10
Dependent Claim
41 words
An electric panel as set forth in claim 8 in which the forward surface of the mounting ledge is long enough to secure at least three receptacle type power outlet fittings for a plug having at least three prongs positioned side-by-side.
Claim 11
Dependent Claim
63 words
An electric panel as set forth in claim 7 in which each of the L-shaped cross-section with a forwardly extending leg engageable by plug-in type terminals of a receptacle type power outlet fitting having at least three prong engaging contact elements; each of said contact points comprising a forwardly extending sheet-like stab disposed in a plane transverse to said legs of said buses.
Claim 12
Dependent Claim
55 words
An electric panel as set forth in claim 7 in which each of the L-shaped cross-section with a forwardly extending leg engageable by plug-in type terminals of a receptacle type power outlet fitting having at least three prong engaging contact elements; each of said forwardly extending legs having notches in line with said mounting hooks.
Claim 13
Dependent Claim
55 words
An electric panel as set forth in claim 10 in which the mounting hooks are spaced apart by a distance sufficient to permit a receptacle type power outlet fitting, for a plug having at least three prongs, to be secured to the forward surface of said mounting ledge in a position between said mounting hooks.
Claim 14
Dependent Claim
30 words
An electric panel as set forth in claim 10 in which the hot contact points are disposed in a row parallel to and transversely spaced with respect to said buses.
