ANSI/CAN/UL 2808:2020

1.1 These requirements cover submetering equipment and open and enclosed type current sensors intended for factory or field installation within the wiring space of enclosures for switches or overcurrent devices. Installation is in accordance with the National Electrical Code, ANSI/NFPA 70 and the Canadian Electrical Code (CE Code), CSA C22.1. These requirements also cover "Service Entrance" enclosed-type current sensors intended for indoor and outdoor use. 1.2 These current sensors are rated for use in a maximum 250 V, 600 V, or 1000 V line-to-line circuit or in a maximum 1500 Vdc circuit. The frequency measurement capability of the sensors is governed by the stated frequency. 1.3 Current sensor conductor leads under the scope of this standard are considered a Class 1 circuit, as defined by the National Electrical Code, ANSI/NFPA 70, and the Canadian Electrical Code (CE Code), CSA C22.1 and are intended to be installed with NFPA 70 Chapter 3, wiring methods and CE Code Section 12, wiring methods. 1.4 This standard does not include investigation of the function of the controlled equipment. 1.5 These current sensors have not been evaluated for accuracy or use with emergency control systems where the function of the control could affect safety. 1.6 These current sensors are intended for use in an ambient temperature of 0 – 40° C (32 – 104° F) unless specifically indicated for use in other conditions. 1.7 These current sensors are intended for use at altitudes up to 2000 m (6562 ft) and in a humidity tolerance of 0 – 95 percent, unless indicated for use in other conditions. 1.8 Unless specifically evaluated and marked “Service Entrance”, these current sensors are evaluated for installation within equipment on the load side of the service equipment overcurrent device.
