PART 3 - EXECUTION

3.1 INSTALLATION

A. Installation shall be in accordance with the NEC , as shown on the drawings, and manufacturer’s instructions.

B. Factory-installed SPD: Panelboard manufacturer s hall install SPD at the factory.

D. Do not perform insulation resistance tests on pa nelboards or feeders with the SPD connected. Disconnect SPD before cond ucting insulation resistance tests, and reconnect SPD immediately aft er insulation resistance tests are complete.

3.2 ACCEPTANCE CHECKS AND TESTS

A. Perform in accordance with the manufacturer's re commendations. In addition, include the following:

1. Visual Inspection and Tests:

a. Compare equipment nameplate data with specificat ions and approved shop drawings.

b. Inspect physical, electrical, and mechanical con dition.

c. Verify that disconnecting means and feeder size and maximum length to SPD corresponds to approved shop drawings .

d. Verifying tightness of accessible bolted electri cal connections by calibrated torque-wrench method.

e. Vacuum-clean enclosure interior. Clean enclosur e exterior.

f. Verify the correct operation of all sensing devi ces, alarms, and indicating devices.

3.3 FOLLOW-UP VERIFICATION

A. After completion of acceptance checks and tests, the Contractor shall show by demonstration in service that SPD are in go od operating condition and properly performing the intended func tion.

3.4 INSTRUCTION

A. Provide the services of a factory-trained techni cian for one 2-hour training period for instructing personnel in the ma intenance and operation of the SPD, on the date requested by the COR.
