Hi-Pot Testing - Dometic Go Power GP-TS-50 User Manual

6. HI-POT TESTING

such a manner that the wiring will interfere with the physical operation of the relay.
Visually inspect for free operation of the relay(s).
6. HI-POT TESTING
(MANUFACTURING COMPANIES ONLY)
NOTE: If the hi-pot test is performed from the plug on the powercord, 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 powercord is unplugged. Verify that the prongs on the powercord
plug are protected so that the hipot 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 powercord
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
must be checked, disconnect the generator wires from the transfer switch and
connect hi-pot test leads to the loose wires. Reconnect wires after testing.
8. If hi-pot test fails, there is a short in the system. The next step is to isolate the
location of the short. Turn off the main breaker in panel and hi-pot test again.
If the test still fails, the fault is between the switch and the panel. Test cord for
