Scope
This part of IEC 60947 specifies requirements for terminal blocks with screw-type or screw-less-type clamping units primarily intended for industrial or similar use and to be fixed to a support to provide electrical and mechanical connection between copper conductors. It applies to terminal blocks intended to connect round copper conductors@ with or without special preparation@ having a cross-section between 0@2 mm2 and 300 mm2 (AWG 24/600 kcmil)@ intended to be used in circuits of a rated voltage not exceeding 1 000 V a.c. up to 1 000 Hz or 1 500 V d.c. NOTE AWG is the abbreviation of ??American Wire Gage?? (Gage (US) = Gauge (UK)) kcmil = 1000 cmil; 1 cmil = 1 circular mil = surface of a circle having a diameter of 1 mil 1mil = 1/1000 inch This standard may be used as a guide for ?C terminal blocks requiring the fixing of special devices to the conductors@ for example quick connect terminations or wrapped connections@ etc.; ?C terminal blocks providing direct contact to the conductors by means of edges or points penetrating the insulation@ for example insulation displacement connections@ etc.; ?C special types of terminal blocks@ for example disconnect terminal blocks@ etc. Where applicable in this standard@ the term ??clamping unit?? has been used instead of the term ??terminal??. This is taken into account in case of reference to IEC 60947-1. Modification to add the following: This standard specifies requirements for terminal blocks with screw-type or screw-less-type clamping units primarily intended for industrial or similar use and to be fixed to a support@ in accordance with Annex DVB@ National Electrical Code@ NFPA 70 (for use in the USA)@ or CSA C22.1?C15 Canadian Electrical Code@ Part I (for use in Canada)@ and NOM-001-SEDE@ Electrical Installations (Utility) ([for use in Mexico]). The wire range for terminal blocks covered by this standard include 0@051 mm2 to 1 010 mm2 (30 AWG to 2 000 kcmil) copper conductors and 3@31 mm2 to 1 010 mm2 (12 AWG to 2 000 kcmil) aluminum conductors. See Annex DVA for aluminum requirements. In Mexico@ 3@31 mm2 (12 AWG)@ 5@26 mm2 (10 AWG)@ and 8@37 mm2 (8 AWG) aluminum conductors are not allowed. The voltage range includes up to 1 500 Vac and 1 500 Vdc.
