4.  GENERAL REQUIREMENTS

4.1  Description.  Solderless wrapped connections shall be made by wrapping a specified number of turns of wire, under tension, around a post having sharp corners.  The sharp corners of the wrappost shall produce high pressure points resulting in indentations of the wire or both the wire and wrappost to meet the requirements of the strip test (see 5.6.1).  The resulting gas-tight, high-pressure points shall provide electrical continuity and mechanical stability.  Wrappost connections covered by this standard shall be either class A or B (see 3.6 and 5.6.2).

a.    Class B wire wraps may be used only in instances where class A wire wraps cannot be accomplished, such as uninsulated wire and coaxial cables.
