Enclosure leakage current test
This test pertains to the Solar 8000M/i, part of the monitoring system.
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.
2. Connect probe to an unpainted, non-anodized chassis ground on the
device 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 EN limits are
different.
5. Set the polarity switch to RVS.
6. Read the current leakage indicated on DMM.
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.
7. Set the GND switch on the leakage tester to CLOSED.
8. Read the current leakage indicated on DMM.
