ABSTRACT:
An electrical busway system comprising a busway uniquely configured for cutting to length in the field. Special connector devices are also disclosed, with features for engaging and immobilizing busway insulators to assure accurate initial alignment of conductors and contact elements prior to joining of connector devices with busway sections. An accessory device, specially adapted to the new busway design, includes a rotatable contact element, slideably received in its rotatable support, which progressively displaces a spring as the contact element is rotated into contact with a busbar carried by a busway insulator. Good electrical contact at both ends of the slideable contact element is assured. The accessory device also includes a positioning element which is rotatable with, but rotationally advanced with respect to, the contact elements, to accurately position, and substantially immobilize an insulator element prior to the contact elements being rotated into restricted, busbar-receiving recesses in the insulator element.
