Notes:
1. Primary protectors are removed for all tests.
2. For EUT containing secondary voltage limiting and current limiting protectors, tests are to be performed at the indicated voltage(s)
and repeated at a reduced voltage and current just below the operating threshold of the secondary protectors.
3. This test is to be performed between the ranges of 100 V to 600 V and is intended to produce the greatest heating affect.
4. Test 5 simulates a high impedance induction fault. Specific information regarding this test is available upon request.
5. These tests are repeated using a short-circuit value just below the operating threshold of the current limiting device, or, if the EUT
uses a fuse as current limiting protection, the fuse may be bypassed and the short circuit current available adjusted to 135% of the
fuse rating.
6. Intra-building, second level lower fault test uses test condition 1 only. The applied voltage is at 120 V rms only.
Second Level AC Power Fault for Customer Premises Equipment
For customer premises equipment, the EUT is tested to the conditions presented in
Table 4.8 and connected to a circuit equivalent to that shown in Figure 4.2. During this test,
the wiring simulator cannot open. For equipment that uses premises type of wiring, the
wiring simulator is a 1.6 A Type MDQ fuse from Bussman. For equipment that is connected
by cable, the wiring simulator is a piece of 26-gauge copper wire.

Notes:
1. Applied between exposed surfaces and Ground
2. The 60 Hz signal is applied with an initial amplitude of 30 V rms and increased by 20% every 15 minutes until one of the following
occurs:
— Voltage reaches the maximum specified
— Current reaches 20 A or the wiring simulator opens
— EUT fails open circuit
3. If the EUT fails open circuit, the test continues for an additional 15 minutes to ensure that another component of the EUT does not
create a fire, fragmentation, or electrical safety hazard.
