A three phase gang-operated high voltage electric disconnect switch assembly comprising:
- a gang-operated switching unit per each electrical phase, each of the gang-operated switching units including at least one high voltage electric disconnect switch including a plurality of high voltage electrical insulators, each gang-operated switching unit mounted in operative arrangement on a linear transverse switch support member, each linear transverse switch support member mounted transversely on a pair of oppositely disposed parallel beams, each parallel beam having a top surface having secured thereto in spaced arrangement a plurality of the linear transverse switch support members with one linear transverse switch support member per electrical phase,
- a drive linkage transverse support member mounted transversely on the pair of oppositely disposed parallel beams,
- each of said linear transverse switch support members configured to support in operative arrangement the plurality of high voltage electrical insulators of the respective gang-operated switching unit, at least one of said high voltage electrical insulators of each of said linear transverse switch support members adapted to be rotatable,
- two of the linear transverse switch support members configured as outer transverse switch support members in operative attachment proximate their ends to respective opposite ends of the pair of oppositely disposed parallel beams and configured to form a unitized rectangular common base,
- the unitized rectangular common base configured to have in a first rectangular configuration a fixed multiple bolt connection between the ends of each of the linear transverse switch support members and the pair of oppositely disposed parallel beams and a fixed multiple bolt connection between the ends of the drive linkage transverse support member and the pair of oppositely disposed parallel beams and configured to have in a second rhomboidal configuration a pivot connection between the ends of each of the respective linear transverse switch support members and the pair of oppositely disposed parallel beams and a pivot connection between the ends of the drive linkage transverse support member and the pair of oppositely disposed parallel beams by removal of all the fixed bolts except one retained bolt at each pivot connection,
- a removable power actuator configured to pull and transform the unitized rectangular common base to a rhomboidal shape in the second rhomboidal configuration to reduce the width of unitized rectangular common base to a predetermined width to allow shipment of the three phase gang-operated high voltage electric disconnect switch assembly on a truck to an electric utility.
