Connecting Devices for Low-Voltage Circuits for Household and Similar Purposes - Part 1: General Requirements
 N JIS C 2814-1

Annotation

This Standard specifies the connecting devices as separate entities for the connection of two or more rigid conductors (solid or stranded) or flexible conductors (complying with JIS C 3664, IEC 60344 or relevant JISs), having a cross sectional area of 0.2mm2 or over to and including 35 mm2 with a rated voltage of 1 000 V or under a.c. at frequency of not exceeding 1 000 Hz, or of 1 500 V or under d.c used for household and similar purposes.

NOTE 1 The rated connecting capacities lower than 0.5 mm2 shall be referred to IEC 60344 and those equal to or higher than 0.5mm2 shall be referred to JIS C 3664 except those conforming to relevant JISs.

NOTE 2 "Rigid conductor" includes both "solid conductor" and "stranded conductor" ("concentric lay stranded conductor" and "compacted circular stranded conductor").  Also, "flexible conductor" refers to "bunch stranded conductor" (see Annex JA)

NOTE 3 In the corresponding International Standard, terminals for AWG conductors are included in the scope; however, AWG conductors are excluded from the scope since they are treated for reference in this Standard.  The relationship between mm2 and AWG size is shown in Annex B.

NOTE 4 The relevant JISs refer to JISs on electric wires which specify the standardrated connecting capacities of Type 2 shwon in 6.2

This Standard is not applicable to the connecting devices that require the use of special tools other than for twist-on connecting devices and insulation piercing connecting devices.
