Our fabric cables come in 2-core (2x0.75mm) and 3-core (3x0.75mm). Please consult with your licensed electrician in regards to what your project needs. When in doubt, 3-core cable should cover all bases under AS/NZS electrical standards.
The number of cores relates to the number of insulated internal wires within a cable. The 0.75mm measurement indicates the cross-sectional area of the internal copper conductors. This changes with Large Section Cable to 1.5mm.
Electricians match the number of internal wires directly to what each lamp holder requires for safe operation and grounding.
Double-insulated plastic, porcelain, or bakelite lamp holders featuring two internal connection points (Active and Neutral) use 2-core cable (2x0.75mm).
Metal lamp holders require 3-core cable (3x0.75mm). The third wire serves as an essential Earth connection to ground the conductive metal housing under Australian standards.
Yes. 3-core cable can be used on 2-core components. Electricians have the ability to leave the Earth wire safely unattached.
Ultimately, you need to check with your licensed electrician as to what they need to complete your lighting installation safely.
