This standard applies, when required by the relevant product standard, to low-voltage switchgear and controlgear hereinafter referred to as equipment or device and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.
This standard states the general rules and common safety requirements for low-voltage switchgear and controlgear, including:
– definitions;
– characteristics;
– information supplied with the equipment;
– normal service, mounting and transport conditions;
– constructional and performance requirements;
– verification of characteristics and performance;
– environmental aspects.
This standard does not apply to low-voltage switchgear and controlgear assemblies which are dealt with in IEC 61439 series, as applicable.
1.1DV.1 D2 Modification of 1.1 by adding the following
1.1DV.1.1 This equipment is intended for installation in accordance with CSA C22.1, Canadian Electrical Code (CE Code, Part I); Mexican Official Standard, NOM-001-SEDE; and the US National Electrical Code (NEC), NFPA 70.
1.1
This Standard covers assemblies of wiring terminals and supporting blocks for copper conductors, copper and aluminum conductors, and aluminum conductors rated at a maximum of 1500 V and 2000 kcmil, intended to provide for the connection of wiring designed to be used in accordance with the Rules of the Canadian Electrical Code, Part I.
1.2
These terminal blocks are intended to support permanently and to insulate wire terminations and joints from each other and from the surface on which the terminal block is mounted, where the absence of such support or insulation could result in a hazard.
1.3
Terminal blocks can be of various designs, such as sectional, modular, or one-piece.
1.4
Terminal blocks can employ a combination of connectors.
1.5
Protective conductor terminal blocks (PCTB) are covered under CSA C22.2 No. 60947-7-2.
1.6
In this Standard, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.1
This standard applies to enclosures for electrical equipment intended to be installed and used in nonhazardous locations in accordance with the Canadian Electrical Code, Part I, CSA C22.1, the provisions of the National Electrical Code, NFPA 70, and the provisions of Mexico's Electrical Installations, NOM-001-SEDE, as follows:
a) Enclosures for indoor locations, Types 1, 2, 5, 12, 12K, and 13; and
b) Enclosures for indoor or outdoor locations, Types 3, 3X, 3R, 3RX, 3S, 3SX, 4, 4X, 6, and 6P.
1.2
This standard covers additional environmental construction and performance requirements for enclosures. The general requirements for enclosures are contained in CSA C22.2 No. 94.1, UL 50, and NMX-J-235/1-ANCE (See Annex B, Ref. No. 10) or the end-use product standards that are to be used in conjunction with this standard.
1.3
This standard does not cover the requirements for protection of devices against conditions such as condensation, icing, corrosion, or contamination that may occur within the enclosure or that may enter via conduit or unsealed openings.
1.4
Where an individual product standard contains requirements that are at variance with those of this standard, the requirements of the individual product standard take precedence.
1DV DR Modification of Clause 1 to replace with the following:
This part of IEC 60079 standard specifies the construction and testing of intrinsically safe apparatus intended for use in explosive atmospheres, and for associated apparatus which is intended for connection to intrinsically safe circuits which enter such atmospheres.
This Type of Protection is applicable to electrical equipment in which the electrical circuits themselves are incapable of causing ignition of a surrounding explosive atmosphere. This includes electrical equipment which contains circuits that are intrinsically safe only under certain conditions, for example under battery supply with mains supply removed.
This document is also applicable to electrical equipment or parts of electrical equipment located outside the explosive atmosphere or protected by another Type of Protection listed in IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0, where the intrinsic safety of the electrical circuits in the explosive atmosphere may depend upon the design and construction of such electrical equipment or parts of such electrical equipment. The electrical circuits exposed to the explosive atmosphere are assessed for use in such atmospheres by applying this document.
This document applies to sensors connected to intrinsically safe circuits but does not apply to the protection of catalytic elements for Group IIC or Group IIB + H2.
This document does not apply to Ex Equipment cable glands.
The requirements for intrinsically safe systems are provided in IEC 60079-25 UL 60079-25 and CSA C22.2 No. 60079-25.
This document supplements and modifies the general requirements of IEC 60079-0, UL 60079-0 and CSA C22.2 No. 60079-0 except as indicated in Table 1. Where a requirement of this document conflicts with a requirement of IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0, the requirement of this document takes precedence.
Unless otherwise stated, the requirements in this document are applicable to both intrinsically safe apparatus and associated apparatus, and the generic term "apparatus" is used throughout the standard.
As this document applies only to electrical equipment, the term "equipment" used in the standard always means "electrical equipment".
This document applies to apparatus for use under the atmospheric conditions of IEC 60079-0 UL 60079-0 and CSA C22.2 No. 60079-0 with additional requirements for use at extended atmospheric pressures in the range from 60 kPa (0,6 bar), up to 110 kPa (1,1 bar).
Where references are made to other IEC standards, the referenced requirements found in these standards apply as modified by any applicable US National Differences for the standard (see Clause 2).
