Another risk involved with power lines is indirect contact. Because of the large
magnetic fields created by the currents in the power lines, large voltages may be
induced upon the phone lines via electro-magnetic coupling. In this instance voltages
should be limited to 1000V
PK
and 600V
RMS
by the primary protectors, while the
current will be limited by the current carrying capacity of the 24 gauge wire.
First Level AC Power Fault Criteria
Test conditions for the First Level AC Power Fault Test are shown in Table 4-4. The
EUT is required to pass operationally.

Notes:
1. 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.
2. Test 5 simulates a high impedance induction fault. For specific information, please contact Teccor
Electronics.
Second Level AC Power Fault Criteria
Test conditions for the Second Level AC Power Fault Test are dependent on whether
the EUT is intended for customer premises equipment or non-customer premises
equipment. In both instances, although the EUT is not required to pass operationally, it
may not become a fire, fragmentation, or electrical safety hazard.
Second Level AC Power Fault Criteria for Non-Customer Premises Equipment
For non-customer premises equipment, test conditions are shown in Table 4-5
(it should be noted that test conditions 1, 3, and 4 may be omitted if the EUT has
previously met UL 1459) and test connections are shown in Figure 4-1.
