Overvoltage Test Procedures
Use the following criteria when applying the overvoltage tests presented in Table 4.17:
1. Test Set-up — Equipment is to be mounted as it is intended to be used. Tests may be
2. Indicators — Before testing, two single pieces of cheesecloth are to be wrapped tightly
3. Line Cords — Equipment with a removable telecommunications line cord is to be
4. Functional Circuitry — UL mandates that functional circuitry must be used for each
5. Wiring Simulators — A wiring simulator is used to indicate whether the maximum I
conducted on either the equipment as an assembly, individual subassemblies, or a
partial assembly containing those components which may be exposed to an overvoltage
condition.
around the assembly, subassembly, or partial assembly. The cheesecloth acts as an
indicator for conditions that may result in fire.
connected to the test circuit with a line cord having 0.4 mm (26 AWG) or larger copper
wire conductors and not more than 1 W total resistance.
overvoltage test conducted. This allows repair or replacement of damaged circuitry
before subsequent testing. Alternatively, separate samples may be used for each test.
imposed upon telecommunications wiring has been exceeded. For Tests 1 and 5, a
wiring simulator is to be used unless the equipment is specified for use with a suitable
secondary protector or a secondary protector simulator. The wiring simulator can consist
of one of the following:
a. 50mm length of 0.2 mm (32 AWG) bare or enameled solid copper wire (for test
b. Bussman Mfg. Co. Type MDL-2A fuse (for test condition 1)
c. 300 mm length of 0.4 mm (26 AWG) solid copper wire which connects to a
d. Current probe used with a 300 mm length of 0.5 mm (24 AWG) copper wire (for test
