Abstract
Abstract A compartmentalized cabinet installation for housing motor circuit controls mounted on plug-in modules. Controls such as motor starters and breakers are easily attached to the plug-in modules which allow rapid assembly and disassembly of the controls in associated compartments having power distributing bus bars therein. In order to gain entrance into a compartment, a safety handle must be turned causing actuation of a linked circuit breaker. The cabinet is equipped with a separate trough through which power bus bars pass. Fuses that are easily removed from a power circuit, bridge the bus bars located in the trough and other bus bars supplying power to the plug-in modules.
