1 range. 1.1 This standard applies to unipolar connectors used with all copper or aluminum alloy or copper-clad aluminum conductors or all three conductors to provide contact between current-carrying components.
Compliance with the Canadian Electrical Code, Part 1, C22 of Canada1. The National Electrical Code NFPA-70 of the United States or the electrical installation standard NOM-001-SEDE of Mexico are as follows:
Note: According to the National Electrical Code NFPA 70, copper-clad aluminum conductors can only be used in the United States.
a) Pressure conductor connectors for fixing one or more conductors;
b) Connectors for appliances and equipment that meet the requirements of appliances and equipment;
c) Soldered connectors;
d) for 4 AWG (212 mm2) or larger;
Note: Spliced wire and cable connectors with a range of wire sizes may include less than 4 AWG (21.)2 mm2).
e) Neutral rods;
f) Non-insulated connectors for circuits with rated voltage of 35000V and below;
g) Rated current connectors that are not suitable for general use; And.
h) Insulation piercing connectors.; And.
i) Exothermic welded wire connectors.
1The 1A connector is also suitable for use in accordance with CSA C222 no.291-14 UL 486F evaluates ferrules for the preparation of conductors, or for the evaluation of electricity according to this standard.
Wire connector adapter, conditioned under the following conditions:
a) Use ferrules and adapters according to their ratings and installation instructions.
b) The length of the exposed conductive material maintains the stripping length required by the connector manufacturer.
1.2 This standard applies to connectors for conductors in the following size ranges:
a) Aluminum: 1) 12 AWG (3.)3 mm2) and 10 AWG (53 mm2) solid;
2) 12 awg (3.3 mm2) to 2000 kcmil (1010 mm2) stranded, Class B concentric, compressed and compact; And.
3) 12 awg (3.3 mm2) to 1000 kcmil (508 mm2) stranded single input wire (SIW).
b) Copper-clad aluminum:
1) In Canada, this structure is not allowed.
2) In Mexico, such structures are not allowed.
3) In the United States:
i) 12 awg (3.3 mm2) and 10 AWG (53 mm2) solid; And.
ii) 12 awg (3.3 mm2) to 2 000 kcmil (1010 mm2) stranded, Class B concentric, compression, and Class C concentricity.
C: 1) 30 awg (005 mm2) to 10 awg (53 mm2) solid; And.
2) 30 awg (0.05 mm2) to 2000 kcmil (1010 mm2) stranded, Class B concentric and compressed, and Class C concentric.

e) Rigid (solid and stranded) metric wires, which belong to the above size range and 6 categories, with a size range of 05-2500 mm2, except for AWG KCMIL rulers.
In addition, there are AWG KCMIL ratings that are mandatory and metric wire ratings that are optional.
Note 1: Metric wire dimensions are based on IEC 60228, the IEC standard for insulated cable conductors.
NOTE 2: For example, a connector rated at 6 AWG-250350KCMIL may additionally be rated at 16-120185mm2. See, for example, Appendix C.
f) Other categories and strand configurations as indicated.
1.3 This standard applies to connectors whose current does not exceed the ampacities of an insulated conductor with a temperature rating of 75 or 90°C, depending on the connector's rating, if any.
1.4These requirements cover insulated connectors, caps and caps for voltages of 2000 volts or less, as well as for general circuits with nominal voltage ratings of 35,000 volts or less.
Non-insulated connectors.
In Canada, if permitted and in accordance with Canadian Electrical Code Part 1 C221 Section 36 for installation, non-insulated connectors can also be used for phase-to-phase voltages up to 5000 volts.
Apply. For products intended for use in Canada, CAN CSA-C222 no.0 is given in the general requirements.
1.5 This standard does not apply to:
a) Insulated connectors with voltage levels above 2 000V;
b) Manual twisting of connectors;

e) Terminal screw terminals; And.
f) Bare or clad sleeves for 1 0-20 AWG stranded copper conductors.
Test re Test Requirements:
This standard applies to all alloys, copper-clad aluminum, using copper or aluminum for single-polarity connectors.
