5.3  Solderless wrapped connection.

5.3.1  Process.  Solderless wrapped connections shall be made with either hand or automatic wrapping tools capable of wrapping connections which conform to all requirements of this standard.  The sequence of operations for making wrapped connections shall be as follows (see figure 4).

a.    Verify that the tool meets the requirements specified in 5.4. b.    Insert the stripped wire into the feed slot (hand tools only).

c.        Bend insulated or bare wire into notch in tool to anchor (hand tools only). d.    Place tool (large hole) over the wrappost.

e.    Rotate the tool spindle around the wrappost. f.        Remove tool from wrappost.
