Standards

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 cover aluminum (ERMC-A) and stainless steel (ERMC-SS) electrical rigid metal conduit, nipples, elbows, and couplings in 12 – 155 (3/8 – 6) trade sizes for use as metal raceway for the installation of wires and cables in accordance with CSA C22.1, Canadian Electrical Code, Part 1, NOM-001-SEDE, Standard for Electrical Installations, and NFPA 70, National Electrical Code (see Reference Item No. 1, Annex A). It is the user’s responsibility to determine the appropriate product for the application.

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.

Requirements contained in this Standard cover controls of the light-sensitive or presence-sensitive types, or both; for indoor or outdoor service; intended for the control of indoor or outdoor loads up to maximum of 20 A and maximum 347 V; intended for installations on 50 Hz or 60 HZ systems or DC upto 60 V (for US); and DC up to 42.4 V (for Canada); and intended to be installed in accordance with the National Electrical Code (NEC), NFPA 70, the Canadian Electrical Code (CE Code) Part I, CSA C22.2 No0, and NOM 001 SEDE.

1.1 These requirements cover flat-plate photovoltaic modules and panels intended for installation on or integral with buildings, or to be freestanding (that is, not attached to buildings), in accordance with the National Electrical Code, NFPA 70, and Model Building Codes. 1.2 These requirements cover modules and panels intended for use in systems with a maximum system voltage of 1500 V or less. 1.3 These requirements also cover components intended to provide electrical connection to and mounting facilities for flat-plate photovoltaic modules and panels

1.1 These requirements cover aluminum (ERMC-A) and stainless steel (ERMC-SS) electrical rigid metal conduit, nipples, elbows, and couplings in 12 – 155 (3/8 – 6) trade sizes for use as metal raceway for the installation of wires and cables in accordance with CSA C22.1, Canadian Electrical Code, Part 1, NOM- 001-SEDE, Standard for Electrical Installations, and NFPA 70, National Electrical Code (see Reference Item No. 1, Annex A). It is the user’s responsibility to determine the appropriate product for the application.

This standard establishes the minimum energy performance standards (MEPs) for refrigerating appliances and relevant test method to specify the energy label.  It also specifies the energy label requirements.

1.1    These requirements cover the installation of lightning protection systems on all types of structures other than structures used for the production, handling, or storage of ammunition, explosives, flammable liquids or gases, and other explosive ingredients including dust.

1.2    These requirements apply to lightning protection systems that are complete and cover all parts of a structure. Partial systems are not covered by this standard.

 
1.4    Adjacent structures shall be considered separate structures.

1.5    Adjacent structures with lightning protection shall be considered part of the structure if the adjacent structure’s lightning protection system complies with this standard and is connected to the lightning protection system of the structure in accordance with Section 10.4.

1

1.7    Free standing Walkways shall be considered an adjacent structure under the following conditions:

     a)  It is separated by a fire wall and conductive media that is shared by both facilities has an SPD in accordance with Section 13.

1.8      This standard does not cover lightning protection for:

       a)  Electric transmission lines or open air distribution racks,

       b)  Outdoor substations or switch yards, and

       c)  Electric generators unenclosed by a building other enclosed structure.

1.9    Enclosed generators and conventional building structures at or associated with generators or power plants, etc. are covered.

1

1.1    These requirements cover industrial control panels intended for general industrial use, operating from a voltage of 1000 volts or less. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum.
