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 shorted plug. If the test passes, turn on the main breaker, and turn
on all branch breakers except one. Retest each branch circuit individually
until the shorted circuit is isolated. Repair the fault and retest. The hi-pot test
is successful when there are no more fault indications.
