Abstract: An electrical distribution system having a meter socket, load center combination apparatus is disclosed. The meter socket, load center combination apparatus has an enclosure having a meter socket section with a meter socket configured to receive an owner utility meter, an owner load center with a plurality of locations configured to receive circuit interface devices, and a combination cross bus connection section extending between sides of the enclosure, the cross bus connection section having one or more side openings configured to allow electrical connection to one or more main cross bus bars of a main panel, a parallel energy source disconnect, and a parallel energy source coupled to the parallel energy source disconnect. Methods of configuring electrical distribution systems are disclosed, as are other aspects.

Abstract: An electric load center having a basepan having a surface with a modular extension mounting foot extending from a lower end wall of a circuit breaker support rail for receiving a modular extension basepan, the modular extension mounting foot having a slot for receiving a flexible snap hook of the modular extension basepan to secure the modular extension basepan to the basepan.

Abstract: An attachment for attaching a main circuit breaker in an electrical panel has a uniquely constructed hold-down for the circuit breaker and a headed screw for fastening the hold-down in the panel. The hold-down is a non-electrically conductive part, such as a plastic. A circuit-breaker-engaging projection for engaging a circuit breaker projects from a first side of the hold-down body and a gripping tab projects from a second side of the body opposite the first side. A shank of the headed screw passes through a through-hole in the hold-down body to thread into a hole in a base pan. The screw is tightened against the hold-down body to hold it, and in turn the main circuit breaker, in place. In such an installed condition, the main circuit breaker cannot be removed easily from the panel unless the screw is intentionally unscrewed by a tool sufficiently to allow movement of the hold-down to a position that enables the main circuit breaker to be removed.

Abstract: An electric load center having a basepan having a surface with 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.

Abstract: A bonding screw is pre-assembled in a distribution panel in a non-bonding position that does not bond a neutral bar within the panel enclosure to the enclosure wall. This allows an installer of the panel to select between the option of maintaining the bonding screw in the pre-assembled non-bonding position and the option of positioning the bonding screw from non-bonding position to a bonding position. A basepan is disposed within the enclosure between the neutral bar and the enclosure's back wall. The non-bonding position is defined by the screw shank thread having a threaded engagement with a through-hole in a basepan, the head of the bonding screw being spaced from the neutral bar, and the shank of the bonding screw being spaced from the enclosure's back wall. The bonding position is defined by the head of the electrically conductive part being disposed against the neutral bar and the shank being threaded into an extruded hole in the enclosure's back wall.

Abstract: An electric load center having a basepan having a surface with two spaced apart integrally formed wall members extending upward from the surface forming a barrier between the bus bars of the load center.

Abstract: An electric load center having a basepan having a surface 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.

Abstract: An electric load center having a basepan having a surface, 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.

Abstract: A basepan for an electric load center 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.
