PART 3 - EXECUTION

3.1 INSPECTION

A. Installer must examine areas and conditions under which electrical grounding connections are to be made and notify Contractor in writing of conditions detrimental to proper completion of work. Do not proceed with work until unsatisfactory conditions have been corrected in a manner acceptable to Installer.

3.2 INSTALLATION OF ELECTRICAL GROUNDING

E. Test the existing service entrance grounding electrode system and implement corrections or improvements as necessary to achieve 5 ohms or less resistance to ground. If required, provide a new service entrance grounding electrode system including bonding to metallic cold-water pipe, structural steel and building re-bar, if available.

F. All ground connections shall be made on surfaces which have been cleaned of all paint, dirt, oil, etc., so that connections are bare metal to bare metal contact. All ground connections shall be exothermic weld type (CADWELD or equal), except where equipment or devices are provided with a factory supplied terminal connector that is listed for use with that device or equipment.

I. In all cases where flexible metallic conduit, nonmetallic rigid conduit or liquid tight flexible conduit is used, a green wire ground conductor shall be used to provide ground continuity between the equipment of device and the conduit raceway system.

J. Provide a separate green wire ground conductor for each branch circuit originating from each panelboard. This ground shall be used to ground the device or load fed, and shall be bonded to components of the raceway system, such as junction boxes, starter or disconnect switch enclosures, equipment cases, etc. The green wire ground conductor shall terminate in the panelboard at the green wire ground bus. Ground conductors for branch circuits shall be of size indicated in NEC, except minimum size ground conductor shall be No. 12 AWG.

K. Each branch feeder originating at the main panel shall have a green wire ground conductor originating at the ground bus in the switchboard and terminating at the green wire ground bus in the panelboard. This green wire ground conductor shall be of size indicated in NEC except in no instance smaller than No. 8 AWG.

L. The green wire ground conductor is in addition to the neutral conductor and in no case shall the neutral conductor serve as the grounding means.

M. Multiple conductors in a single lug not permitted. Each grounding conductor shall terminate in its own terminal lug.

N. Grounding connections shall be tested and certified by the installer. The service entrance ground and each building ground shall have a maximum of 5 ohms resistance to ground.

Supplemental grounding shall be provided if necessary.

1. Grounding Tests: The resistance of electrodes (main service, building feeders, transformers, lighting poles, etc.) shall not exceed 5 ohms and shall be measured by the Contractor before equipment is placed in operation. Testing shall be performed on all grounding electrode installations. Testing shall be 2-point method in accordance with IEEE Standard 81. Submit all ground test readings to the Engineer in tabulated format, indicating each ground test location by main service, panel feeder tag, transformer tag, pole # and location, etc., at substantial completion.
