Panelboard with provision for optional use with main breaker or main lugs with spaced insulators supporting main bus bars

Claim 1

An electric distribution panel including a relatively shallow panlike housing; first and second inulsator members of substantially equal size and shape mounted in spaced relation to the rear wall of said housing and extending forward therefrom; first and second elongated main conductors extending generally parallel to each other in a common plane parallel to said rear wall; each of said insulator members including a plurality of recesses wherein the ends of the conductors are entered to provide the sole support operatively mounting the conductors to the insulator means; a circuit breaker locating and supporting rib positioned between said main conductors with the ends of said rib being supported by said insulator members; each of said main conductors, at locations spaced along the length thereof, being provided with means defining circuit breaker connecting points; each of said insulator members including first and second guide apertures positioned in the vicinity of the respective first and second main conductors and slightly forward thereof to direct energizing cables for said panel to cable receiving openings of main lug means positioned inboard of the insulating members and connected to those of said connecting points at the ends of said conductors.
