Understanding Cable Gauge and Its Significance

When looking at a house wiring wire size chart Australia, one of the most important factors to consider is the cable gauge. Cable gauge is the measure of the wire’s thickness and dictates how much current it can carry without overloading or burning out. This is crucial for ensuring the safe operation of your electrical system. Generally speaking, the thicker the cable, the more current it can carry, so always make sure to check the cable gauge before buying your cables.

Types of House Wiring Cables

When choosing the right cable for your house wiring, there are several different types to choose from. The most common type of cable used in home wiring is called Romex. This type of cable is made of two or more insulated conductors, along with a bare ground wire. It is commonly used for general purpose wiring and is available in sizes ranging from 16 gauge to 10 gauge.

Another type of cable commonly used in wiring is THHN or THWN. This type of cable is specifically designed for use in wet environments, such as outside or near water sources. It is also used in more demanding applications, such as large motors and pumps, where more power is needed. THHN is available in sizes ranging from 14 gauge to 4 gauge.
