P, <br />D. Except where otherwise approved by the Engineer no splices will be allowed in <br />manholes, hndholes or other below grade located boxes. <br />3.04 GROUNDING <br />A. The entire electrical system shall be completely and effectively grounded as <br />I� required by the NEC and as specified hereinafter. <br />B. All metallic raceways shall be mechanically and electrically secure at all joints <br />I� and at all boxes, cabinets, fittings and equipment. Metallic raceways entering <br />the motor control center control panels or other electrical boxes shall be <br />grounded to the appropriate ground bus. All metallic raceways shall be <br />electrically continuous throughout the entire conduit system. Bond wires shall <br />be used in exterior concrete pull boxes. <br />C. The ground plane shall consist of a minimum of 2 -5/8" x 10' copper ground <br />rods spaced at least 10' apart. Rods and system ground shall be connected <br />with a #6 copper ground to the service entrance ground. The ground <br />resistance shall be tested and additional rods or plates added to achieve a dry <br />season resistance not exceeding 5 ohms. <br />ii <br />3.05 CONDUCTOR COLOR CODING <br />I� <br />A. All conductors shall be color coded as specified hereinafter. Color coding shall <br />be by means of colored insulation material, colored braid or jacket over the <br />insulation, or by means of suitable colored permanent, non -aging insulation <br />tape equal to Scotch #471 or "Texcel 98" applied to conductors at each <br />outlet, cabinet or junction point. <br />I�� <br />be to: <br />B. The following system of color coding shall strictly adhered <br />1 . Ground leads, green. <br />2. Grounded neutral leads, white. <br />3. Ungrounded phase wires of a 120/208 volt, 3- phase, 4 -wire system, <br />black, red and blue. <br />4. All control leads, other than line connected "hot" leads, shall be yellow, <br />orange and brown and /or I.P.C.E.A. standard control cable coding <br />provided method of identification is different from method used on <br />power conductors. <br />' <br />C. The color coding assigned to each phase wire shall be consistently followed <br />throughout the Work. <br />END OF SECTION <br />07/03 16050-11 <br />"I <br />03- 4138.A <br />
