Figure 4-2 Second Level AC Power Fault and Current Limiter Connection
Current Limiting Protector Test
The purpose of the Current Limiting Protector Test (Table 4-7) is to determine if the
EUT allows an excessive amount of current flow under power fault conditions. During
this test, the EUT is connected to a circuit equivalent to Figure 4-2 with a 1.6A Type
MDQ fuse from Bussman used as the wiring simulator. If the EUT draws enough
current to open the fuse, then the acceptable time/current criteria has not been met
and external current limiting protectors must be specified for use with that equipment in
the manufacturers documentation.

Short Circuit Test
In addition to the AC Power Fault and Current Limiter Tests, Bellcore compliant
equipment must also pass a Short-Circuit Test. During this test, a short circuit condition
is applied to the following Tip and Ring appearances for thirty minutes while the EUT is
powered and under operating conditions:
Tip-to-Ring, Tip-to-ground with Ring open-circuit.
Ring-to-ground with Tip open-circuit.
Tip and Ring-to-ground simultaneously for thirty minutes.
