ABSTRACT:
An interlock assembly for use with a pair of aligned multiple switch assemblies configured to control the supply of electrical power to an electrical panel. Each multiple switch assembly includes a two-pole transfer switch for a pair of “hot” conductors, and a single-pole transfer switch for a neutral connection. The interlock assembly is movably mounted relative to both of the multiple switch assemblies, and is configured to control a sequence of connection and interruption of each neutral connection relative to switching the hot conductors associated with switching each multiple switch assembly. The interlock assembly prevents the “hot” conductors of each multiple switch assembly from being connected without the associated respective neutral connection having been made in advance. The interlock assembly also ensures that the neutral connection of each multiple switch assembly is interrupted without previous interruption of the connection of the respective “hot” conductors.
