The fuse shall be as declared in table 7.2, item 103, but not less than 16 A. The circuit shall be adjusted such that the prospective current s

21、elected from the table 17.101.1 is obtained at the maximum voltage declared in table 7.2, item 103 and without the protector connected in the circuit. The power factor of the circuit shall not be less than 0,9. In the US and Canada, the fuse shall be as declared in table 7.2, but not less than 20 A

22、for a device rated 150 V or less, or 15 A for a device rated greater than 150 V; but not less than four times the motor full-load nameplate amperes.

27、circuit, without further circuit adjustment, by two 1 m lengths of copper wire having a cross-sectional area as indicated in table 10.2.1 for the current rating of the fuse. If the protector is tested inside the equipment, the cotton is to be wrapped around the equipment enclosure. Cotton shall be w

28、rapped around the protector, if tested alone, during the test. Each manual reset protector shall be subjected to one test in which the short circuit is closed on the protector. If the protector cycles during the test and if the cotton is not ignited, the test shall be continued until the protector p

29、ermanently opens the circuit or the series fuse opens. Cotton used shall be as specified in annex C. 17.101.2 The protector shall be deemed to comply with the requirements of 17.101 provided there is no ignition of the cotton. After the test, accessible metal parts shall not be live. _ PRINTEDINCANADAIMPRIMEAU CANADA
