Single Core PVC Insulated Copper Building Wire

What Goes Wrong With Single Core Wire

Single core building wire is bought by the kilometre and checked by the inspector. What matters is that the conductor is the cross-section printed on the jacket, that the insulation survives being drawn through conduit, and that the colour code matches the regulations in the destination market.

• Conductor cross-section under the printed rating
• Insulation dragging or tearing during long conduit pulls
• Colour codes that do not match local wiring regulations
• Coils running short of the marked length
