Abstract
An electrical boot for the bus bar joints of electrical metal-clad switchgear is taught. The boot is formed by taking a piece of heat shrinkable material, disposing it over a joint or similar construction, heating and shrinking the material so that it shrinks to the shape of the joint or construction in question while at the same time, providing on two opened edges thereof a clamped chill bar which does not allow those portions to cohere to each other so that the boot may be removed after the formation process and easily disposed upon a bus bar joint located within the tight confines of a metal-clad switchgear cabinet. The process may be utilized to form metal-clad switchgear having bus bars with a heat-shrunk insulating boot on the joints thereof. Furthermore during the production process, a bolt envelope simulating template or jig may be utilized to fill out the area on the finalized boot which roughly corresponds to the outer dimensions of the bolt and nut arrangement.
