Applications of 12/2 NM-B:

Type NM-B Copper Building Wire is commonly applied in residential building wiring and branch circuits for switches and outlets. wire is for dry indoor applications. 12/2 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 is 600 volts. The 12/2 electrical wire is easily installed because it is specifically designed for easier pulling. 

The range of NM-B 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 are specified in Article 334 of NEC

The particular applications of NM-B in sizes 12/2 rated 20 Amps include:

• Lighting circuits
• Outlet cIrcuits
• Small appliances
• HVAC circuits
• Bathroom circuits
