3-7
Document no. 2044677-001
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(5) Read and record the current leakage indicated on the tester.
(6) Change leakage tester switches to:
•
Polarity - NORMAL
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(7) Read and record the current leakage indicated on the tester.
(8) Change leakage tester switches to:
•
Polarity - NORMAL
•
Neutral - OPEN
•
GND (Earth) - CLOSED
(9) Read and record the current leakage indicated on the tester.
If measured reading is greater than the appropriate specification below, the device under test
fails. Contact GE Technical Support.
2.7.1 Acceptance criteria NC (Normal condition)
•
(USA only) 300 µA, and the device under test is powered from 100-120 V/50-60 Hz
•
(USA only) 300 µA, and the device under test is powered from a center-tapped 200-240
V/50-60 Hz, single phase circuit (UL Split Phase Exemption)
•
500 µA, and the device under test is powered from a non-centertapped, 200-240 V/50-60
Hz, single-phase circuit
2.7.2 Acceptance criteria SFC (Single fault condition) - ground (earth), line or
neutral open
•
(USA only) 300 µA, and the device under test is powered from 100-120 V/ 50-60 Hz
•
(USA only) 300 µA, and the device under test is powered from a center-tapped 200-240
V/50-60 Hz, single phase circuit (UL Split Phase Exemption)
•
1000 µA
NOTE: Center-tapped and non-center-tapped supply circuits produce different leakage
currents and the UL and IEC limits are different.
