14.7 Resistance to arcing test
請教UL 817 以下標準的中文意思？這抗電弧測試是否只針對連接器呢 ？
14.7 Resistance to arcing test
14.7.1 The connector fittings that were subjected to 50 cycles of operation in the Overload test described
in 14.4 shall perform acceptably when subjected to an additional 200 cycles of operation under the
overload test conditions following the temperature test and the repeated retention of plugs test.
14.7.2 Alternatively, six representative connector fittings may be subjected to the 50 cycles of operation
in the Overload test described in 14.4, followed by the Temperature test and repeated Retention of blades
test on the connector fittings, and then, to determine resistance to arcing, a second, previously untested
set of connector fittings may be subjected to 250 cycles of operation under the overload-test conditions.
14.7.3 The attachment plug used for this test may be changed after every 50 operations. There shall not
be any sustained flaming of the material in excess of five seconds duration. There shall not be any
electrical tracking or the formation of a permanent carbon conductive path that results in a dielectric
breakdown, as determined by the application of a 60 Hz essentially sinusoidal potential of 1500 V
Cord Connector 、Socket、Receptacle 都要做此測試 也就是带电插拔，会产生打火的效果 这250下插拔看打火烧灼叫抗电弧还好理解，前面14.4小节50下叫过载，这词意太牵强了。
