A vertical bus bar arrangement has three phases, each consisting of two U-shaped members disposed to form an H-configuration and a flat, rectangular bar spaced away from and on each side of the H-configuration. Insulator members are arranged between the bus bar arrangement and the brace members. The insulator members have extended portions raised away from the surface of the bus bars for receiving part of the two interconnected barrier members. The insulator members and a substantial portion of the barrier members form a labyrinth between phases. The barrier members have knockout portions for the electrical connections of the bus bars, and also portions for covering the raw edges of the bus bars in the areas through which the runbacks extend. The crossbars are connected to the bus bars by at least two connectors, one of which extends in the gap formed by the conductors of the bus bars, and one of which extends alongside the flat bar and parallel to the first connector. Flanges of the connectors are connected to the crossbars.
