NOTE
If either reading is greater than the appropriate specification below, the
device under test fails. Contact GE Technical Support.

300 µA (0.3 volts on the DMM), and the device under test is powered from
100-120 V/50-60 Hz
„ 300 µA (0.3 volts on the DMM), and the device under test is powered from a
centered-tapped 200-240 V/50-60 Hz, single phase circuit
„
500 µA (0.5 volts on the DMM), and the device under test is powered from a
non-center-tapped, 200-240 V/50-60 Hz, single-phase circuit
NOTE
Center-tapped and non-center-tapped supply circuits produce different
leakage currents and the UL and IEC limits are different.
8. Set the power switch of the device under test to OFF.
Enclosure leakage current test
Perform this test to measure current leakage through exposed conductive surfaces on
the device under test during normal operation.
1. Configure the leakage tester like the circuit shown below with GND switch
OPEN and polarity switch NORM .
enclosure leak
2. Connect probe to an unpainted, non-anodized chassis ground on the unit under
test.
3. Set the power switch of the device to ON .
4. Read the current leakage indicated on DMM.
NOTE
Center-tapped and non-center-tapped supply circuits produce different
leakage currents and the UL and IEC limits are different.
5. Set the polarity switch to RVS .
