Standards

1.1 These requirements cover molded-case circuit breakers, molded-case switches, and circuit-breaker enclosures rated up to 1500 V dc, intended for use with photovoltaic (PV) systems and Ref. No. 1 of Annex B.1.2 These requirements are intended to be used in conjunction with the requirements in Ref. No. 2 of Annex B, except as modified or supplemented by this Standard.1.3 These requirements do not cover molded-case circuit breakers or molded-case switches intended for use in battery circuits.

1.1 This Standard applies to grounding and bonding equipment for use in accordance with the Canadian Electrical Code, Part I, CSA C22.1, in Canada, the National Electrical Code, NFPA 70, in the United States, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico.

This standard specifies the requirements for cord sets and power-supply cords employing molded-on or assembled-on fittings, rated 600 V maximum, and intended for use in non-hazardous locations in accordance with the National Electrical Code, ANSI/NFPA 70. It also specifies the requirements for molded-on general-use attachment plugs and cord connectors etc.

These requirements cover the shielded and no shielded medium-voltage power cables that are described in Tables 1.1 (single-conductor) and 1.2 (multiple-conductor). Multiple-conductor cables may include one or more individually jacketed non-conductive optical-fiber members. These electrical andhybrid electrical and optical-fiber cables are for use (optical and electrical functions associated in the case of a hybrid cable) in accordance with Article 328 and other applicable parts of the National Electrical Code (NEC), ANSI/NFPA 70.

This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the National Electrical Code (NEC), NFPA 70, in Guyana. See Annex A for the complete list of types and voltage ratings covered by this Standard and the specific electrical codes for which they are intended, and Annex B for a summary of construction and test requirements for these types. Table 1 provides a summary of the maximum conductor temperature, voltage ratings, and the number of insulated conductors for the types to which this Standard applies.

This Standard also specifies the requirements for submersible pump cables, with or without jackets, in Deep Well Submersible Water-Pump Cable, Section 7. No type-letter designations are assigned to these cables.

Products within this Standard might have applications not covered by the electrical codes listed in 1.1.

1.1 This Standard specifies the requirements for 600 V single-conductor, thermoplastic-insulated wires and cables, for use as follows: In Guyana, in accordance with ANSI/NFPA 70, National Electrical Code (NEC).Note: See Annex A for the complete list of wire types and voltage ratings covered by this Standard and the specific electrical codes for which they are intended.

These requirements cover attachment plugs, receptacles, cord connectors, inlets, current taps provided with wiring terminals for flexible cord, and flatiron and appliance plugs – all intended forconnection to a branch circuit for use in accordance with the National Electrical Code, ANSI/NFPA 70.

This standard contains specific details of the conductors, of the insulation, of the jackets and other coverings, and of the methods of sample preparation, of specimen selection and conditioning, and of measurement and calculation that are required in wire and cable standards1.2 The requirements for the particular materials, construction, performance, and marking of an individual type of wire, cable, or flexible cord are stated in the standard covering the finished type. They are not part of this reference standard.1.3 In each case in which an element of this standard does not apply, the standard covering the finished type so states and specifies what does apply.

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.
