![]() This third conductor provides a ground for safety purposes and can be used for various purposes, such as three way switching. The extra conductor is wrapped in red, which is why it is referred to as 12-3 wire. The designation 12/3 indicates AWG 12 wire with three conductors (two AC hot and AC neutral). ![]() It is also important to keep in mind that when using this type of wire, you must adhere to the National Electrical Code to ensure safe installation. This type of cable is often used for powering three-way switches or running circuits in larger buildings. This type of cable also includes a bare copper ground wire.Īs the name suggests, Romex 12/3 has three conductors with a total cross-sectional area of 12AWG, making it thicker and more durable than the 12/2 version. It consists of three insulated conductors, two of which are hot (black and red) and one that is neutral (white). Romex 12/3 wire is a type of electrical cable that is suitable for indoor use. What Is Romex 12 3 Wire? What Is The Difference Between 12/2 and 12/3 Romex When the 12/3 Romex is used in conjunction with a grounding system, it ensures that all potential shock sources are properly grounded, providing the highest level of safety and protection. This type of cable is typically used for general household wiring and is ideal for powering small appliances and lighting fixtures.įor more robust protection, it is recommended to use the 12/3 Romex which has an additional third conductor that provides a dedicated ground wire. It consists of black(hot) and a white(neutral) wire as well as an unsheathed copper wire for ground along with an outer non-metallic jacket. The 12/2 Romex wire does have a ground wire. In these cases, the ground wire helps protect against electric shock and other potential hazards.Īdditionally, 12/2 cable is also suitable for wiring three-way switches and other applications where two hot wires are required. It’s also commonly used for powering motors, such as those in air conditioners, refrigerators, and clothes dryers. This type of wire is typically used for household wiring, such as powering switches, outlets, and light fixtures. ![]() The 12/2 cable is the ideal wire for any electrical project that requires two conductors and a ground wire. Romex 12/2 wiring is easy to install, safe, and cost effective, making it an ideal choice for residential electrical wiring needs. It is also commonly used for three-way switching in a home or office. This type of wiring is typically used to run circuits from a breaker panel to lights, receptacles, and appliances in a home or office. The 12-2 gauge indicates that the two insulated wires are 12-gauge thick and the ground wire is 2-gauge thick. It consists of two insulated black and white conductors, plus an uninsulated bare copper ground wire. Romex 12 2 wire is a type of electrical wiring specifically designed for residential and light commercial use. 7 Conclusion What Is Romex 12 2 Wire? What Is The Difference Between 12/2 and 12/3 Romex
