2.5mm is commonly used for behind sockets, while 1-1.5mm is most often used for lights (depending on how many lights you have in a circuit).

Does Australia use AWG or SWG?

2. The British version – called the SWG (Standard Wire Gauge). We Australian’s usually use the American version but not all of the time. Some shops don’t tell you which standard they are using so the best thing to do is find out the exact measurement of the wire and work it out yourself.

### What is thicker 12g or 14g wire?

The diameter of 12 AWG wire is 0.0808 inches, while 14 AWG is 0.0641 inches. The thickness of 12 AWG wire is 26% more than the thickness of 14 AWG wire. In the gauge system for steel music wire, a bigger number means a bigger wire.

### What power can a 6mm cable take?

2 Answers from MyBuilder Electricians. 6mm twin and earth cable (which this almost certainly is) can be backed up by a maximum of a 32a MCB, even lower if other factors are involved. You’ll need that 10mm cable and a 40a MCB unfortunately as your shower is going to draw over 32a.

Can you mix 1mm and 1.5 mm cable?

IET Forums – Mixing cable sizes. So it’s ok even if I have wired half of the circuit in 1.5 and then do the rest in 1mm. Yes, mixed cable sizes are fine provided that the smallest cable is compliant for the size and type of OCPD. AND that the voltage drop for the entire circuit is within acceptable limits.

## How is the current of a wire measured?

Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn’t overheat.
