override the chattering condition and the meter will have time to register the

reduced voltage. If this condition exists, identify and correct the low voltage

situation before proceeding further.

leads. Occasionally on these models, the wiring connections will get folded into

the can in such a manner that the wiring will interfere with the physical operation

of the relay. Visually inspect for free operation of the relay(s).

5. Hi-Pot Testing

(MANUFACTURING COMPANIES ONLY)

NOTE: If the hi-pot test is performed from the plug on the power cord, the test

may only hi-pot the cord itself; it may not test the RV wiring beyond the switch.

The hi-pot test should be performed from either the transfer switch output or from

the main panel.

Test as follows:

1. Turn on all circuit breakers in the panel.

2. Make sure the generator is off.

3. Make sure the power cord is unplugged. Verify that the prongs on the power

cord plug are protected so that the hi-pot voltage won’t cause a fault reading from

a short, or cause bodily injury from electrical shock.

4. Turn off or disconnect all appliances that would be damaged by the hi-pot test.

5. Connect the hi-pot leads to:

a) Transfer switch ground bar

b) Transfer switch output terminals hot 1, hot 2 (if present), and neutral.

6. Energize the hi-pot and conduct test. This will hi-pot test for leakage (short)

between the current-carrying conductors and the ground in the entire 120/240

VAC circuitry beyond the transfer switch. In most cases it will also test the power

cord itself. Turn off the hi-pot.

7. Do not test the transfer switch generator input. The hi-pot will damage the time

delay control module in the transfer switch. If the generator wires to the switch
