The spark test shall be performed by the manufacturer as a routine test at the factory on 100 percent of the finished wire in accordance with the spark test method, Section 900, and spark test for power-limited circuit cable and for cable for power-limited fire-alarm ciruits, section 910 of UL1581, and the method described in 45.2 the potential shall be 10 times the voltage rating of
the wire, up to 1000 volts, with a minimum potential of 1500 volts. if the rated voltage is not specified, the potential shall be 3000 volts. for wire rated more than 1000 volts, the potential shall be times the rated voltage with a minmium potential of 10,000 volts. the test potential for wire rated for direct current is specified in table
