ABSTRACT:
A modular section insulator switch having a unique base on which two feeder cable assemblies and at least two trolley line assemblies may be provided in combination with a switch assembly. In use, different sized feeder cable assemblies and switch assemblies may be interchanged quickly while the switch is in-line to accommodate higher amperage feeder cables because of the unique base.
