Applications of Romex 12/3:

Romex Type NM-B Copper Building Wire is commonly applied in residential building wiring and branch circuits for switches and outlets. Romex wire is for dry indoor applications. Romex 12/3 can also be used for various building purposes inside (the temperature should not exceed 90 °C).12/2 NM-B electrical wire can be used in air voids in tile walls. The voltage rating of the 12 Gauge Romex is 600 volts. The 12/3 electrical wire is easily installed because it is specifically designed for easier pulling. 

The range of NM-B Romex applications includes:

• Residential electric systems, including lights, switches, and outlets.
• Branch circuits
• Small appliances, including  microwave ovens, dishwashers, and garbage disposals
• HVAC systems
• In Air Void Applications of Tile Walls
• The applications of NM-B Romex are specified in Article 334 of NEC

Unlike 12/2 wire, which is used for standard circuits and outlets, 12/3 Nm-b electrical wire is used for  circuits where two independent circuits are run together (multi-wire branch circuits), or for special connections that need a third wire, such as a three-way switch or a split receptacle circuit.The particular applications of NM-B Romex in sizes 12/3  rated 20 Amps include:

• Three-Way Switches
• Shared Neutral Circuits/Multi-Wire Branch Circuits
• Split Receptacles
• Two Independent Circuits

 Romex 12/3 Standards:

• ASTM B-3 and B-8
• UL Standard 83
• UL Standard 719
• Federal Specification A-A-59544
• National Electrical Code, NFPA 70. 2011 Edition
• RoHS/ REACH

Construction of Romex 12/3 :
