Standards

This standard applies to pin and sleeve type plugs, receptacles, power inlets, and connectors, rated up to 800 amperes and up to 600 volts ac or dc, and which may include up to eight pilot contacts. These devices are intended to provide power from branch circuits, or are for direct connection to the branch circuit in accordance with the Canadian Electrical Code Part I, the National Electrical Code (NEC),ANSI/NFPA 70, and the Mexican Electrical Code, NOM 001 SEDE, using copper conductors, for use in either indoor or outdoor nonhazardous locations. In Canada, the terminals of a device intended to accommodate aluminum conductors also comply with CSA C22.2 No. 65.

These requirements cover low-voltage ac power circuit breakers as follows: a) Stationary-mounted or draw out-mounted types, b) 2-pole, 3-pole, and 4-pole constructions, c) Manually operated or power operated, and) With or without electromechanical or solid-state type trip device. Revised 1.1 effective April 13, 2017.

The requirements in this standard apply to a low-voltage landscape lighting system and components that consist of an isolating type power unit, low voltage cable or flexible cord, and luminaires. The equipment is intended to be installed in accordance with the National Electrical Code, ANSI/NFPA 70,Article 411.1.1 revised February 24, 2014.

These requirements apply to low voltage lighting systems and components intended for permanent installation and for use in locations in accordance with the National Electrical Code, NFPA 70, Article 411.1.2 These requirements cover: a) Power units in which output is limited to 25 A and below the risk of electric shock voltage levels as defined in 3.19; and b) Class 2, exposed bare conductor, POE, and other low-voltage luminaires and lighting systems.

This standard applies to metallic OUTLET BOXES, flush-DEVICE BOXES, FLOOR BOXES, CONCRETE BOXES, EXTENSIONRINGS, covers, CONDUIT BODIES, BAR HANGERS, bar-hanger assemblies, and all accessories whose principal function is for support of boxes. The products covered by this standard are intended for installation in accordance with the National Electrical Code (NEC), NFPA 70, the Canadian Electrical Code (CEC), Part I, and the Standard for Electrical Installations, NOM-001-SEDE.

These requirements cover nonmetallic outlet boxes, conduit bodies, flush-device boxes, extension rings, covers, floor boxes, floor nozzles, and concrete boxes to be employed in accordance with the National Electrical Code, NFPA 701.2 These requirements do not cover boxes and covers for use in hazardous locations as defined in the National Electrical Code, NFPA 70.1.3 These requirements do not cover cabinets and cutout boxes.

These requirements cover wire binding screw terminals of receptacles and switches rated 15 or 20 A intended for use with solid conductor aluminum building wire, and that require direct connection of wiring conductor(s) to the binding head screw terminal(s) prior to insertion of the device in an outlet box.1.2 These performance requirements for wire binding screw terminals are in addition to the requirements for the products covered by the Standard for Attachment Plugs and Receptacles, UL 498, and the Standard for General-Use Snap Switches, UL 20.

This standard covers portable flexible lighting products with a maximum input voltage rating of 120volts to be used in accordance with the National Electrical Code, ANSI/NFPA 70. These products are provided with a power supply cord and are intended for outline and decorative lighting use.1.2 These requirements cover lighting products incorporating non-replaceable series and series/parallel connected lamps enclosed within a flexible polymeric tube or extrusion.1.3 These requirements also cover flexible lighting products used in light sculptures.1.4 These requirements do not cover lighting products with replaceable lamps.1.5 These requirements do not cover the temporary-use, seasonal decorative-lighting products and accessories with a maximum input voltage rating of 120 V that are covered by the Standard for Seasonal and Holiday Decorative Products, UL 588.

1.1 These requirements cover LED equipment that is an integral part of a luminaire or other lighting equipment and which operates in the visible light spectrum between 400 – 700 nm. These requirements also cover the component parts of light emitting diode (LED) equipment, including LED drivers, controllers, arrays, modules, and packages as defined within this standard.

1.1 This standard describes the apparatus, test methods, and formulas to be used in carrying out the tests and calculations required by wire and cable standards. 1.2 Specific acceptance requirements are found in individual product standards. 1.3 Where a test method indicates a “specified” test parameter or condition, the parameter or condition is found in the individual product standard.
