12-3 MC WIRE 250' COIL

12-3 MC WIRE 250' COIL – Product Description

🔌 What it is

A 250-foot coil of 12/3 MC (Metal-Clad) cable, used for protected 20-amp branch circuits that require an extra conductor (typically a neutral or switch leg).

🧾 What the shorthand means

• 12-3 → wire configuration:
  • 12 AWG copper conductors
  • 3 insulated conductors + ground
  • (black, red, white + bare/green ground)
• MC → Metal-Clad cable (armored aluminum or steel jacket)
• WIRE → electrical cable assembly
• 250' COIL → 250-foot spool

⚡ What it’s used for

12/3 MC cable is used for 120V or 120/240V circuits that need an extra conductor, such as:

• Three-way and four-way switch circuits
• Split receptacle circuits
• Ceiling fans with separate light and fan control
• Multi-wire branch circuits (where permitted)
• Some 240V circuits requiring a neutral

🔥 Electrical characteristics

• Typically used on 20-amp circuits
• Provides physical protection via metal armor
• Suitable for commercial, industrial, and exposed residential runs
• Copper conductors inside armored jacket

🧠 Simple explanation

This is a 250-foot roll of 20-amp electrical wire inside a metal protective jacket, used when you need an extra conductor for switching or multi-function circuits.
