12 Gauge Wire

What is 12 Gauge Wire?

12 gauge wire, also known as AWG 12 or #12 wire, is a standardized wire size in the American Wire Gauge (AWG) system. It represents a specific diameter and cross-sectional area of the wire. In the AWG system, a lower gauge number corresponds to a thicker wire.


Properties of 12 Gauge Wire

12 gauge wire possesses several important properties:

  • Conductivity: Due to its relatively larger cross-sectional area, 12 gauge wire offers efficient conductivity for electrical currents.
  • Strength: Its thicker diameter contributes to enhanced mechanical strength and durability.
  • Flexibility: While not as flexible as finer gauge wires, it still offers pliability for various applications.
  • Temperature Resistance: It can withstand moderate levels of heat without significant performance degradation.
  • Voltage Handling: 12 gauge wire is suitable for applications requiring higher voltages and currents.
  • Compatibility: It can be used with a variety of connectors and terminals.

Applications of 12 Gauge Wire

The versatility of 12 gauge wire makes it indispensable in numerous industries:

  • Residential Wiring: It is commonly used for household wiring, including circuits, outlets, and appliances.
