Following is posted for Mel. The rational for limiting the maximum wrap over the many years was to allow the wire to be removed (if necessary) after initial soldering. It was concluded that often we attach wires to terminals as a design consideration to allow subsequent replacement of component/elements and there was less chance for damage if the wire did not overlap itself or contain several wraps making the removal more difficult. Often we require these additional design attachments at subsequent assembly build or in fielded hardware that may not be readily apparent at each phase but would prevent or complicate the subsequent operation. This is especially true for class three where these specifications were applied. There should be adequate strength in the solder connection with a nominal wrap as prescribed, and these standards allowed disposition which did not necessarily require rework.
