UL 2808-2020 pdf free download.Energy Monitoring Equipment. 9.13 The insulation of internal wiring is considered to be a suitable insulating barrier if it complies with 10.1, and all temperatures measured within the current sensor, when adjusted for maximum rated ambient, do not exceed the temperature rating of the conductor insulation. 10 Field Wiring 10.1 Current sensors field wiring leads and electrical sleeving shall be rated minimum 300 V for current sensors marked “250 V”, minimum 600 V for current sensors marked “600 V”, minimum 1000 V for current sensors marked “1000 V”, and “1500 Vdc” for all others. All conductor insulation and conductor sleeving shall be rated minimum 90°C (194°F). 10.2 Each field-wiring lead shall be copper. Conductors smaller than 0.75 mm 2 (18 AWG), but not smaller than 0.32 mm 2 (22 AWG) for a single conductor and 0.21 mm 2 (26 AWG) for a multi-conductor cable, shall be permitted to be used. 10.3 Field wiring leads of indoor-use current sensors shall be suitable for contact with exposed live parts of a Class 1 circuit and/or routing through the same conduit with other Class 1 circuit conductors. The conductors shall consist of Class 1 wiring or appliance wiring material with insulation that meets the following: a) At least 0.75 mm (30 mils) “Minimum Average” thickness with at least 0.68 mm (27 mils) thickness “Minimum-At-Any-Point”; or b) At least 0.4 mm thick (16 mils) thickness “Minimum-At-Any-Point” and additional electrical sleeving that is also minimum 0.4 mm thick. Sleeving shall also be rated in accordance with 10.1, above. 10.4 Heat shrink tubing shall meet the above thickness requirements “After Heating”. 10.5 The insulation thickness requirements of field wirings leads shall be met for each conductor individually or by a jacket or sleeve around a group of conductors. Exception: Internal wiring and the portion ofany field wiring lead that is located within the current sensor case mayhave insulation ofanythickness, so long as the insulation is rated in accordance with 10.1. 10.6 Field wiring leads of an enclosed-type current sensor shall comply with 10.1 and 10.2. Additionally, field wiring leads shall be hard-service or junior hard-service flexible cord, rated for outdoor use and water resistant (such as type SOOW or SJOW). 10.7 In lieu of field wiring leads, a current sensor may use a connector and cable set if it meets all of the following parameters: a) Cable/Connector assembly is rated in accordance...
