Abstract
An electrical busway system includes a joint assembly having a joint housing with an upper plate and a lower plate. The lower plate has a nut-receiving hole. A top mounted bolt secures a plurality of electrical conductors to the joint housing, the conductors being mounted between the upper plate and the lower plate. A nut is connected to a threaded end of the bolt, the nut having a main body positioned at least in part within the nut-receiving hole and a tightening end positioned outside the nut-receiving sleeve. A nut gasket is provided for the main body of the nut within the nut-receiving hole to form a sealed zone for preventing water entry into the joint housing.
