C. A plastic marking tab shall be provided to label each individual terminal <br /> block. Each tab shall have a unique number/letter for each terminal <br /> which is identical to the "elementary" and "loop" diagram wire <br /> designation. Numbers on tabs shall be machine printed and 1/8-inch <br /> high. <br /> d. Terminal blocks shall be physically separated into groups by the level of <br /> signal and voltage served. Power and control wiring above 100 volts <br /> shall have a separate group of terminal blocks from terminal blocks for <br /> wiring below 100 volts, intermixing of these two types of wiring on the <br /> same group of terminal blocks is not allowed. <br /> e. As a minimum, provide a ground terminal or connection point for the <br /> power system grounding conductor for each terminal block group. <br /> f. 'Terminate field wiring on the "field side" of the terminal blocks. Do not <br /> connect internal panel wiring to the "field side" of the terminal blocks. <br /> Do not connect field wiring to the "panel side" of the terminal block. <br /> g. Provide a separate common or neutral terminal for every two (maximum) <br /> inputs and/or outputs or as coordinated with the interconnect diagrams. <br /> h. Terminal blocks shall be, DIN rail, and 600V rated. <br /> i. Provide terminal blocks with "follower"plates which compress the wires <br /> and have wire guide tangs for ease of maintenance. Terminal blocks <br /> which compress the wires with direct screw compression are <br /> unacceptable. <br /> j. All power, control and instrument wires entering and leaving a <br /> compartment shall terminate on terminal blocks. <br /> 2. Control Panel Terminal Blocks <br /> a. Power Distribution, 120 VAC <br /> 1) Terminal Blocks: Compression -clamp, black bodies, 600 volt <br /> rating, Entrelec M4/6 or approved equal. <br /> 2) Fuse Blocks: Compression Clamp, black bodies, 600 volt rating, <br /> with fuse blown indicator, Entrelec ML10/13.SFL or approved <br /> equal. <br /> b. Control Circuits, Analog and Digital <br /> 1 ) Terminal Blocks: Compression-clamp, grey bodies, 600 volt rating, <br /> Entrelec M4/6 or approved equal. <br /> 2) Fuse Blocks: Compression Clamp, grey bodies, 600 volt rating, <br /> Entrelec M4/8.SF or approved equal. <br /> C. Provide a separate fuse and neutral terminal block for each LLC input or <br /> output card. <br /> d. Analog input and output terminal blocks, in addition to terminal block <br /> numbering, shall have "+," "-" and ground prefabricated symbol plastic <br /> terminal label inserts. <br /> July 2007 Division III-192 NEI Phase II Water and Sewer <br /> CIP Nos. 7468, 7589, 7590 <br />
