English
Follow the steps below to ground test a CE Source Four jr/Zoom
luminaire.
1. Plug the luminaire into the PAT outlet and attach the test clip
to the PAT point on the luminaire.
2. Set the PAT device to test at 10 amperes and press the GO/
TEST button.
If your PAT device doesn't allow you to change the amperage, it
can still be used for the test. However, the earth tether, which
connects the burner assembly to the body of the unit, may get
hot enough to cause injury and could become permanently
discoloured. This is normal for test currents above approximately
20 amperes.
The PAT device should read less than 0.5 ohms. Most Source
Fours give a reading of less than 0.1 ohms, if in good condition.
The Insulation test
The insulation proves that the internal insulation is in good
condition. You can use standard PAT devices to perform the
insulation test. Follow the steps below to test the luminaire's
insulation.
1. Plug the luminaire into the PAT outlet and attach the test clip
to the PAT point on the luminaire.
2. Set the PAT device to test at 500 volts D.C., then press the
G0/TEST button.
A reading below 1M ohms indicates a possible or imminent
failure. Moisture build-up around the lamp holder or in the
connector or foreign matter accumulated around electrical
connections can cause a low reading.
Why a CE Source Four jr/Zoom may give a fail reading
The majority of appliances must fulfill a ground resistance
requirement of 0.1 ohms or less. Some simple, low-cost PAT
devices assume the 0.1 requirement and do not offer a method
for reading the actual resistance or for setting the fail level to 0.5
ohms. These devices may provide a fail reading for an acceptable
unit if the resistance is slightly above 0.1 ohms. If in doubt, check
with your PAT device supplier and verify that the PAT device can
correctly test a luminaire for the 0.5 ohm condition.
How often to test
Your local regulatory authority has guidelines on the testing
frequency.
