Standards

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.

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.

1.7    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    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.

This International Standard specifies requirements for metallic, non-metallic and composite cable ties and their associated fixing devices used for the management and support of wiring systems in electrical installations.

Cable ties and associated fixing devices may also be suitable for other applications and where so used, regard should be taken of any additional requirements.

This standard does not contain requirements that evaluate any electrical insulation properties of the cable tie or mechanical protection of the cables provided by the cable tie.

This standard does not consider the mechanical interface of a fixing device to a solid surface such as a wall or ceiling.

This British Standard specifies requirements for sheets of factory-made machine-welded steel fabric for the reinforcement of concrete, manufactured from ribbed bars conforming to BS 4449:2005, or manufactured from wire conforming to BS 4482 for wrapping fabrics D49 and D98.

NOTE 1 Where the term “bar” is used in this standard, it includes bar or recoiled product conforming to BS 4449:2005. For clarity only. It can also include wire conforming to BS 4482 for wrapping fabrics only.

This standard specifies the general labelling requirements for electrical equipment, fittings and electrical appliances and their detachable heating element (s) if any, offered for sale in Guyana.

This Guyana Standard shall be applied to all electrical equipment, fittings and electrical appliances and should therefore be a standard for a particular products. It shall be applied in conjunction with the labelling requirements of this standard.

IEC 61511-2 provides guidance on the specification design , installation operation and maintenance of safety instrumented functions and related safety instrumented system as defined in IEC 61511-1. This standard has been organized so that each clause and sub clause number herein addresses the same number in IEC 61511-1 (with the exception of the annexes).
