An electric load center having an enclosure with a push-in screw holder fixture, a door latch comprising a one-piece molded member having a flexible tongue which urges the door latch toward the hinged door edge keeping a hook biasedly engaged with an underside edge of the trim, neutral bar having an elongated body portion with a trapezoidal shaped cross-sectional area with outwardly sloping downwardly extending side walls having apertures for insertion of electrical wires, a neutral tie bar adapted to be electrically connected to the enclosure of the load center, a main lug insulator having trough-shaped longitudinally extending compartments and first and second support legs for positioning aver the neutral tie bar, a basepan having a surface with integrally formed posts with an undercut extending around its periphery for securing a component of the load center to the surface by heat staking, the surface having two spaced apart integrally formed wall members extending upward from the surface forming a barrier between the bus bars of the load center, the surface having a tab with a tapered lower edge and a prong extending from a side edge of the tab for capture by lances found in the enclosure of the load center, the surface having a neutral bar wire guide comprising a wall upwardly extending from the surface member and having semicircular slots extending therethrough at an upper surface for receiving and guiding a return wire into an aperture in the neutral bar, the surface having a modular extension mounting foot extending from a lower end wall of a circuit breaker support rail for receiving a modular extension basepan, the mounting foot having a trapezoidal shaped slot for engagement by a correspondingly shaped ramp of the modular extension basepan, the modular extension mounting foot further having a slot for receiving a flexible snap hook of the modular extension basepan to secure the modular extension basepan to the basepan.
