scope:
This Standard applies to single-polarity, hand- or tool-applied splicing wire and cable connectors intended for use with all alloys of copper, aluminum conductors, or copper-clad aluminum conductors, or all three, in accordance with the Canadian Electrical Code Part I, C22.1, in Canada, the National Electrical Code, NFPA-70, in the United States of America, or the Standard for Electrical Installations, NOM-001-SEDE, in Mexico, as follows:
Note: Copper-clad aluminum conductors are for use only in the United States in accordance with the National Electrical Code, NFPA 70.
a) connectors intended to hold two or more conductor(s);
b) connectors intended for use in appliances and equipment that comply with the requirements for such appliances and equipment;
c) connectors intended for use with 6 AWG (13.3 mm2) or smaller conductors; and
d) uninsulated connectors that are used in circuits rated 8 000 V and less.
Note: Examples of splicing wire connectors include twist-on connectors, insulation-piercing or displacement connectors, spring-action connectors, tool-applied crimp, mechanical set-screw connectors, etc.
This Standard is intended for splicing wire connectors suitable for use with conductors in the size ranges as follows:
a) Aluminum:
1) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and
2) 12 AWG (3.3 mm2) to 6 AWG (13.3 mm2) stranded, Class B concentric, compressed, and compact.
In México, the use of aluminum conductors is permitted only with thermoset insulation and for sizes of 6 AWG (13.3 mm2) and higher.
b) Copper-clad aluminum:
1) In Canada, this construction is not allowed.
2) In Mexico, this construction is not allowed.
3) In the United States:
i) 12 AWG (3.3 mm2) and 10 AWG (5.3 mm2) solid; and
ii) 12 AWG (3.3 mm2) to 6 AWG (13.3 mm2) stranded, Class B concentric, compressed, and Class C concentric.
c) Copper:
1) 30 AWG (0.05 mm2) to 10 AWG (5.3 mm2) solid; and
2) 30 AWG (0.05 mm2) to 6 AWG (13.3 mm2) stranded, Class B concentric and compressed, and Class C concentric.
d) Compact-stranded copper conductors:
In Canada and Mexico, for 8 AWG (8.4 mm2) and 6 AWG (13.3 mm2).
In the United States this is not applicable.
e) Rigid (solid and stranded) metric wire falling within the ranges of the above AWG sizes.
Note: For example, a connector rated for 6 AWG (13.3 mm2) - 14 AWG (2.1 mm2) may be additionally rated for 10 - 2.5 mm2.
f) Other class and strand configurations as indicated by marking.
These requirements cover splicing wire connectors intended for:
a) copper-to-copper;
b) aluminum-to-aluminum
c) copper-clad aluminum-to-copper-c
d) copper-to-aluminum or copper-clad aluminum and
aluminum-to-copper-c
e) all of the above.
This Standard is intended for splicing wire connectors suitable for currents not exceeding the ampacity of insulated conductors rated 75 °C or 90 °C, in accordance with the rating of the connector.
This Standard does not apply to:
a) Deleted;
b) insulated splicing wire connectors intended for use at voltage levels in excess of 600 V [1 000 V in a sign or luminaire];
c) terminal wire connectors;
d) wire binding screw terminals;
e) built-in terminal connectors on devices rated less than 30 A and intended for outlet box mounting or having provision for stress relief;
f) built-in terminal connectors on devices having integral cable clamps;
g) flat quick connect terminals; and
h) soldering lugs.
