<p>An electrical plug (21) includes six equally angularly spaced axially extending tubular insulators (22) which have a central internal annular ridge (23) against which a thimble (13) and a socket (14) are collectively secured by the operation of bolt (15). A phase barrier (16) is a structural member being engaged at opposed ends (31, 32) by respective plates (27, 29). The plates are forced toward each other and into clamping engagement with insulators (22) by the action of bolts (33) which are threadedly engaged within complimentary bores in barrier (16).</p> |
