ABSTRACT:
The improved plug-in base assembly of the present invention provides a means for complying with European Health and Safety requirements and particularly the requirement of IEC 439-1 paragraph 7.4.2.2. Subparagraph 7.4.2.2.3 generally requires that live parts be shielded such that they cannot be contacted when a door or cover normally protecting them is opened or removed. This requirement provides additional protection to the installer of a tap-off device against unintentional contact with the uninsulated edges of bus bars exposed through the plug-in openings. The additional protection is provided by a finger barrier which covers the normally exposed uninsulated edge of a bus bar. The finger barrier permits the electrical connectors of a tap-off unit to pass through the plug-in opening and make an electrical connection while preventing any unintentional contact of the installers fingers with the uninsulated edge of the bus bar.
