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.
