- 15 - ABSTRACT An improved panel board construction is described, including an extruded insulative base pan having integral means for slidably engaging at least one main-line bus bar and a neutral con- nector element, each having a plurality of electrical contact points. The base pan also includes means for preventing current flow through the base pan between any two of the contact points of the main-line bus bars. The prevention means includes a protrusion extending from the base pan having a tortuously formed surface thereon. The panel board is provided with interchangeable main- line lugs which may be used to directly contact the main-line bus bars or, alternatively, support a main-line circuit breaker between the lugs and the main-line bus bars. The base pan is symmetrically formed by an extrusion process so that it may be adaptable for use with a variety of panel board sizes simply by shearing the base pan to form the appropriate length.
