During coldweather, particular attention shall be paid to the manufacturer’s minimum installation temperature. Cableshall not be installed when the temperature is at or below the manufacturer’s minimum installationtemperature. At the Contractor’s option, the Contractor may submit a plan, for review by the Engineer, forheated storage of the cable and maintenance of an acceptable cable temperature during installation whentemperatures are below the manufacturer’s minimum cable installation temperature.

Cable shall not be dragged across pavement or earth. When cable must be coiled, lay cable out on acanvas tarp or use other appropriate means to prevent abrasion to the cable jacket.

For phased projects, the tests must be completed by phase and results meeting thespecifications below must be maintained by the Contractor throughout the entire project as well as duringthe ensuing warranty period.

Earth resistance testing methods shall be submitted to the Engineer for approval. Earth resistance testingresults shall be recorded on an approved form and testing shall be performed in the presence of theEngineer. All such testing shall be at the sole expense of the Contractor.

Should the counterpoise or ground grid conductors be damaged or suspected of being damaged byconstruction activities the Contractor shall test the conductors for continuity with a low resistanceohmmeter. The conductors shall be isolated such that no parallel path exists and tested for continuity. TheEngineer shall approve of the test method selected. All such testing shall be at the sole expense of theContractor.

After installation, the Contractor shall test and demonstrate to the satisfaction of the Engineer thefollowing:

b. That all affected circuits are free from unspecified grounds.

c. That the insulation resistance to ground of all new non-grounded series circuits or cable segmentsis not less than 50 megohms.

d. That the insulation resistance to ground of all non-grounded conductors of new multiple circuitsor circuit segments is not less than 50 megohms.

e. That all affected circuits are operable. Tests shall be conducted that include operating eachcontrol not less than 10 times and the continuous operation of each lighting and power circuit for notless than 1/2 hour.

f. That the impedance to ground of each ground rod does not exceed 25 ohms prior to establishingconnections to other ground electrodes. The fall-of-potential ground impedance test shall be used, asdescribed by ANSI/IEEE Standard 81, to verify this requirement.

Two copies of tabulated results of all cable tests performed shall be supplied by the Contractor to theEngineer. Where connecting new cable to existing cable, ground resistance tests shall be performed on thenew cable prior to connection to the existing circuit.
