Abstract

Abstract A dielectric housing for mounting a pair of electrical conductors in place between the meter section and the distribution section of a multimetering service entrance panelboard which sections are separated by a sheet metal barrier for preventing unauthorized service access to bus bars within the meter section; the housing comprising a pair of duplicate diecast plastic housing members which when assembled is located within an opening in the barrier for mounting and maintaining a pair of conductors in place between the meter section and the distribution section; the assembled housing members having external grooves for engagement with peripheral portions of the barrier forming the opening for the dual purpose of supporting the housing in place and of preventing access to the meter section through the opening; and the assembled housing members also comprising an enclosed compartment through which the conductors extend and in which integral projection portions of the two housing members are disposed in transverse alignment for maintaining prescribed spacing between the conductors; and the housing members having pairs of spaced conductor-receiving openings in the end walls and edge walls which openings are enlarged at the outer surfaces of the end and edge walls for providing greater oversurface clearance between the conductors than air clearance, and which housing members include corresponding projections and recess means at the walls of the abutting members for increasing the oversurface clearance or electrical creepage distance between the conductors and the barrier.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 368 words
An enclosed metering and distributing panel comprising metal walls and a barrier forming an enclosure, at least one set of meter sockets mounted within the enclosure, the barrier having an aperture proximate to the set of meter sockets, bus bars connected to one pair of the set of meter sockets, rigid conductors connected to another pair of the set of meter sockets and extending through the aperture to spaced positions external of the enclosure, the external end portion of the conductors being stab-like members adapted for connection to circuit breaker means, means for mounting the rigid conductors in spaced relation with respect to each other and to the periphery of the aperture and comprising a dielectric housing structure forming an enclosing compartment and having integral projections comprising conductor-support surfaces and opening means for holding the conductor in place, the dielectric housing structure extending through and occupying a portion of the aperture and having opposite side walls, opposite end walls and opposite edge walls, each opposite side wall having groove means engaging opposite peripheral portions of the barrier around the aperture for maintaining the housing structure in place, the dielectric housing structure also having an external oversurface clearance projection extending from each opposite edge wall and in planar alignment with the groove means, one of the projections occupying the remaining portion of the aperture, one of the end walls having at least one pair of conductor-receiving openings and at least one of the edge walls having similar openings, the integral projections comprising a longitudinal projection and transverse projection means for dividing the compartment into three chambers, the longitudinal projection extending from said one end wall having the conductor-receiving openings and to the transverse projection, the transverse projection means being spaced from the other end wall and forming therewith a first chamber which chamber communicates with the other of the openings in the edge wall, the longitudinal projection forming second and third chamber adjacent respective edge walls, the second chamber communicating with one of the openings in the end wall and with one of the openings in one edge wall, and the third chamber communicating with the other of the openings in the end wall and with the first chamber.
Claim 2
Dependent Claim 368 words
An enclosed metering and distributing panel comprising metal walls and a barrier forming an enclosure, at least one set of meter sockets mounted within the enclosure, the barrier having an aperture proximate to the set of meter sockets, bus bars connected to one pair of the set of meter sockets, rigid conductors connected to another pair of the set of meter sockets and extending through the aperture to spaced positions external of the enclosure, the external end portion of the conductors being stab-like members adapted for connection to circuit breaker means, means for mounting the rigid conductors in spaced relation with respect to each other and to the periphery of the aperture and comprising a dielectric housing structure forming an enclosing compartment and having integral projections comprising conductor-support surfaces and opening means for holding the conductor in place, the dielectric housing structure extending through and occupying a portion of the aperture and having opposite side walls, opposite end walls and opposite edge walls, each opposite side wall having groove means engaging opposite peripheral portions of the barrier around the aperture for maintaining the housing structure in place, the dielectric housing structure also having an external oversurface clearance projection extending from each opposite edge wall and in planar alignment with the groove means, one of the projections occupying the remaining portion of the aperture, one of the end walls having at least one pair of conductor-receiving openings and at least one of the edge walls having similar openings, the integral projections comprising a longitudinal projection and transverse projection means for dividing the compartment into three chambers, the longitudinal projection extending from said one end wall having the conductor-receiving openings and to the transverse projection, the transverse projection means being spaced from the other end wall and forming therewith a first chamber which chamber communicates with the other of the openings in the edge wall, the longitudinal projection forming second and third chamber adjacent respective edge walls, the second chamber communicating with one of the openings in the end wall and with one of the openings in one edge wall, and the third chamber communicating with the other of the openings in the end wall and with the first chamber.
Claim 3
Dependent Claim 21 words
The apparatus of claim 1 in which housing structure comprises separable housing members comprising abutting edges which members support the conductors.
Claim 4
Dependent Claim 46 words
The apparatus of claim 1 in which the spacing between inner surfaces of the side walls is substantially equal to the width of the conductors, and in which the abutting edges of the edge walls and end walls are substantially equally spaced from the side walls.
Claim 5
Dependent Claim 39 words
The apparatus of claim 2 in which the groove means comprise a first groove in the outer surface of one of the housing members and a second groove in the outer surface of the other of the housing members.
Claim 6
Dependent Claim 72 words
The apparatus of claim 3 in which the opening means for holding the conductors in place comprise a first pair of spaced conductor-receiving slots in one of the end walls and edge walls and a second pair of spaced conductor-receiving lots in the other of the end walls and edge walls of each member, and the first and second slots of one member being aligned with corresponding slots in the other member.
Claim 7
Dependent Claim 30 words
The apparatus of claim 5 in which the first pair of slots are in one end wall and the second pair of slots are in one of the edge walls.
Claim 8
Dependent Claim 36 words
The apparatus of claim 5 in which the external portions of the slots in the end and edge walls are enlarged, whereby the electrical creepage distance between the conductors is greater than the air distance therebetween.
Claim 9
Dependent Claim 25 words
The apparatus of claim 5 in which the projections are within the enclosing compartment and extend inwardly from the inner surface of the edge wall.
Claim 10
Dependent Claim 51 words
The apparatus of claim 5 in whiCh the abutting edge of one housing member has a projecting portion that has a length and thickness of lesser dimensions than those of the edge wall, and the abutting edge of the other housing member having a corresponding recess for receiving the projection portion.
