CONNECTIONS WRAPPED ON TERMINALS WITHOUT SHARP CORNERS SHOULD BE CONSIDERED TEMPORARY AT BEST. Please be aware that solderless connections of this type *depend* on the sharp corners of the post biting into the wire for the gas tight connection. This is true with STRIPPED wire too. If you wrap onto a terminal without *sharp* corners, consider it *at best* a temporary connection only slightly better than if you had wrapped the turns with your fingers. That's why wire-wrap posts are either square or rectangular and have been, well before the existance of the tools that are supposed to bite through the insulation. Wire-wrap(r) is a registered trade mark of Gardner-Denver. Charlie ...!{cmcl2 ihnp4}!lanl!crs crs@lanl.arpa
