Table 4.7 Second Level AC Power Fault Test for Non-Customer Premises Equipment
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)
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
6. Intra-building, second level lower fault test uses test condition 1 only. The applied voltage is at 120 V rms only.

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

— Voltage reaches the maximum specified
— Current reaches 20 A or the wiring simulator opens
— EUT fails open circuit

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.
