Constructions include step up, step down, insulating, and autotransformer type transformers as well as air-cooled, dry, and compound-filled type reactors.

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.
