<br />Drawings. The units shall be listed and approved by Underwriters'
<br />Laboratories for heavy duty entrance use and where applicable, shall
<br />be dual horsepower rated for both standard one-time or dual -element
<br />fuses. The fusible switches shall be group mounted in panel -type
<br />construction. Each switch shall be equipped with Class 'R' rejection
<br />type fuse clips per Bussman or Littlefuse KTN-R, Class "R" type.
<br />2.4.10.2 Each switch is to be enclosed in a separate steel enclosure. The
<br />enclosure shall employ a hinged cover for access to the fuses which
<br />shall be interlocked with the operating handle to prevent opening the
<br />cover when the switch is in the on position. This interlock shall be
<br />constructed so that it can be released with a standard electrician's tool
<br />for testing fuses without interrupting service. The units shall have
<br />padlocking provisions in the offposition and the operating handle
<br />position shall give positive switch position indication, i.e. horizontal
<br />oft; diagonal on. Switches shall pass industry standard I2T
<br />withstandability tests and fuse race tests as described elsewhere in the
<br />Specifications.
<br />2.4.10.3 All fusing -as manufactured by Bussman or Littlefuse; dual -element
<br />and current limiting as shown on the Drawings.
<br />2.5. Contactors
<br />2.5.1 Contactors shall be manufactured by Square'D', Siemens, or General Electric;
<br />or others as approved by Publix in writing specifically for this project.
