More About This Product

Description
These requirements cover suspended ceiling grid low voltage/extra-low voltage systems and equipment intended for installation and use in accordance with the: In Canada: Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, CSA C22.1, In the United States: National Electrical Code (NEC), ANSI/NFPA 70. The suspended ceiling grid low voltage/extra-low voltage systems covered by this standard are intended to be installed as a suspended ceiling grid that provides mechanical support for the ceiling tiles and provides electrical connections between the low voltage/extra-low voltage power supply and the low voltage/extra-low voltage equipment. The low voltage/extra-low voltage system consists of the following components: a) An isolating type low voltage/extra-low voltage power supply with output(s) operating at 30 V (42.4 V peak) or less and not exceeding Class 2 power limits, b) A grid rail power distribution system to provide power from the Class 2 power supply to one or more pieces of Class 2 powered equipment, and c) Class 2 powered equipment that is electrically connected to the suspended ceiling grid low voltage/extra-low voltage system
