A plug-on neutral (PON) device includes a housing that defines a phase cooperation portion configured to physically cooperate with phase buses of a bus assembly. The phase cooperation portion is configured to be electrically isolated from the phase buses and stabilize the PON device when installed on the bus assembly. A neutral cooperation portion is configured to physically cooperate with the neutral bus and to physically stabilize the PON device when installed. An electrical connector disposed at the neutral cooperation portion is configured to electrically connect to the neutral bus at an external end and to electrically connect to a conductive current path at its internal end. A lug assembly has one or more conductive terminal lugs, each terminal lug configured to receive current from an external neutral source via an aperture in the lug end of the housing and to electrically connect to the current path.
