Maintenance: Electrical Safety Tests

Ground (Earth) Wire Leakage Current Tests

Perform this test to measure current leakage through the ground (earth)
wire of the equipment during normal operation.

1.

Set the leakage tester switches as follows:

Selector knob - 1,

GND switch - OPEN,

Polarity switch - NORM,

Power switch - OFF.

2.

Connect the DMM to the METER jacks on the leakage tester. Set the
DMM to measure AC millivolts.

3.

Connect the power cord of the device under test to the power
receptacle on the rear of the leakage tester.

127(

The device under test is to be tested at its normal operating
voltage.

4.

Set the leakage tester power switch to ON.

5.

Set the power switch of the device under test to ON.

6.

Read the current leakage indicated on DMM. If the reading is greater
than the appropriate specification below, the device under test fails
and should be repaired and tested again.

300 microamperes (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.

127(

Center-tapped and non-center-tapped circuits produce different
leakage currents and the UL and IEC limits are different.

7.

Set the polarity switch on the leakage tester to RVS (reverse).

8.

Read the current leakage indicated on DMM. If the reading is greater
than the appropriate specification below, the device under test fails
and should be repaired and tested again.

300 microamperes (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
