Current Limiting Protector Test
The purpose of the Current Limiting Protector Test, presented in Table 4.9, 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 that shown in Figure 4.2 with a
1.6 A 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 have not been met, and
external current limiting protectors must be specified for use with that equipment in the
manufacturer’s documentation.
Short-circuit Test
In addition to the AC Power Fault and Current Limiter Tests, equipment must also pass a
Short-circuit Test to comply with GR 1089. During this test, a short-circuit condition is
applied to the following Tip and Ring appearances for 30 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 30 minutes
At no time will the short circuit exceed 1 W. For equipment with more than one twisted pair,
the short circuit is applied to all twisted pair simultaneously. To comply with the short circuit
test, the EUT must function normally after the short-circuit condition is removed, and a fire
hazard may not be present. The equipment shall not require manual intervention to restore
service.
