What size cable is used for lighting?Lighting circuits are generally run in 1mm2 two-core-and-earth cable, but particularly long circuits can use 1.5mm2 cable to compensate for the drop in voltage experienced on long cable runs.
Article first time published onHow do I know if my wire is 12 or 14-gauge?
Here’s a simple visual. Twelve gauge is about the thickness of a nickel, and 14-gauge is about the thickness of a dime. Also, look at the breaker for the circuit in question to see if it’s a 15-amp or a 20-amp breaker. A 20-amp circuit requires wire that’s 12-gauge or larger.
