When you ask any electrical contractor about the best electrical wiring to use for household electrical wiring and chances are, you will be given the option to use either a cable or a wire.
A Cable is a type of electrical wiring that’s enclosed in an elastic PVC sheath or cover and mostly color coded. Cable used for inside home wiring has NM-B label, which means that the cable is a non-metallic. Thus, it has 194 degrees heat rates. Most cable types has 2 or 3 number of wires, which are designated as hot, the other is neutral while, the ground has no insulation casing. The wire color code refers to the weight of the interior of the cable insulation where a white cable has 14 gauges and the yellow for 12 gauges wire. For the thicker 10 gauges wire, the color code designated is orange. The gray color cable is usually a bundle of smaller wires wrapped with PVC sheath.
Wire types with THHN label or otherwise known as Thermoplastic High heat Resistant Nylon Coated are the most common type of electrical wire used by Sydney Electricians. The other type is with THWN or known as the Thermoplastic Heat and Water Resistant Nylon Coated wire.

Knowing the wire specifications helps a lot in undertaking any electrical wiring projects. For basement electrical wiring for wall outlets, track lighting and canister lighting, a 15-amp circuit with 14 gauge wires is recommended. A garage using 1 20 -amp circuit with 12-gauge wire will be fine specially when having workbenches, overhead lights and garage door opener. For additional safe and protection for rain and snow, North Sydney Electricians would recommend using GFCI receptacles.
However, before doing an electrical home project, it is best to look and read about local wiring codes and each specification required in meeting the code. There is also a need for a permit and a visit from an inspector to meet before any electrical home wiring project can be completed.
