ABSTRACT:
The present invention provides an interior assembly for an electrical distribution device having a fuse for each phase in a circuit. The interior assembly includes a plurality of modules having an operating mechanism for opening and closing a switch contact. The switch contact is connected to each fuse and phase of the circuit. Each module has a housing and a mechanism for demountably securing one of the modules to at least one adjacent module. The securing mechanism is manually operated and integrally formed with the housing of each module. The present invention also provides a method of assembling the interior assembly of an electrical distribution device having a fuse for each phase in a circuit. The step of the method includes manually and demountably affixing a plurality of modules to one another without discrete fasteners. The plurality of modules have an operating mechanism for opening and closing a switch contact. The switch contact is connected to each fuse and phase of the circuit.
