SYSTEM FUNCTIONAL TESTS

OPERATIONAL TESTS AND ADJUSTMENTS

PART 5

INTRODUCTION

Following home standby electric system installation and periodically thereafter, the system should be tested Functional tests of the system include the following:

Manual transfer switch operation.

System voltage tests.

Generator Tests Under Load.

Testing automatic operation.

Before proceeding with functional tests, read instructions and information on tags or decals affixed to the generator and transfer switch. Perform all tests in the exact order given in this section.

MANUAL TRANSFER SWITCH OPERATION

"V-TYPE" TRANSFER SWITCHES:

1.On the generator panel, set the AUTO-OFF-MANUAL switch to OFF.

2.Turn OFF the "Utility" power supply to the transfer switch using whatever means provided (such as a "Utility" main line circuit breaker).

3.Set the generator main line circuit breaker to OFF or "Open".

DANGER: BE SURE TO TURN OFF ALL POWER VOLTAGE SUPPLIES TO THE TRANSFER SWITCH BEFORE ATTEMPTING MANUAL OPERATION. FAILURE TO TURN OFF POWER VOLTAGE SUPPLIES TO THE TRANSFER SWITCH MAY RESULT IN DANGEROUS AND POSSIBLY LETHAL ELECTRICAL SHOCK.

4.Remove the manual transfer handle from the enclosure.

5.Place open end of the manual transfer handle over transfer switch operating lever.

6.To connect "Load" terminal lugs to the "Standby" power source, move, the handle upward.

7.To connect "Load" terminals to the Utility" power source, move the handle downward.

8.Actuate the switch to "Utility" and to MANUAL several times. Make sure no evidence of binding or interference is felt.

9.When satisfied that manual transfer switch operation is correct, actuate the main contacts to their "Utility" position ("Load" connected to the "Utility" power supply).

ELECTRICAL CHECKS

Complete electrical checks as follows:

1.Set the generator main circuit breaker to its OFF (or open) position.
