All joints shall be made so as to prevent the passage of concrete <br />inside the conduit to form obstructions or cause cable abrasions. <br />5. Pullbox covers in all areas shall finish 3- inches above crown of <br />adjacent ground elevation. <br />6. A 5/8 -inch by 10 -foot copperclad ground rod shall be driven in the <br />bottom of each pullbox. All bond wires and pullbox cover shall be <br />bonded to the ground rod. <br />PART 3 - EXECUTION <br />3.01 CONDUIT INSTALLATION <br />1 05/04 <br />A.

Bends in metallic raceways shall be made while "cold" and in no case shall <br />the raceways be heated. Raceways shall not be bent through more than <br />900. The radius of bends shall not be less than six (6) times the internal <br />diameter of the raceway. Not more than four (4) (equivalent 901) bends <br />will be permitted between outlets, the bends at the outlets being counted. <br />160501 -9 <br />03 -4465 <br />
