10/3 MC Cable – Durable Metal Clad Cable for 120/240V Multi-Circuit Power
10/3 MC Cable is a flexible, armored electrical cable designed for 30-amp 120/240V circuits. It includes three 10 AWG copper conductors and a ground wire, making it ideal for residential and commercial branch circuits that require both 120V and 240V service. Commonly used in dryers, air conditioners, and subpanel feeders.
Common Applications for 10/3 MC Cable
- Electric dryers and ranges
- Split-phase 120/240V HVAC equipment
- Residential subpanel feeders
- Commercial lighting circuits
- Multi-wire branch circuits
Benefits of 10/3 MC Cable
- Supports 120V & 240V Loads: Includes a neutral wire for balanced load applications
- Flexible Installation: No conduit needed in many dry locations
- Protected Design: Aluminum armor shields from mechanical damage
- UL & NEC Approved: Code-compliant for safe, legal installations
- Time-Saving: Preassembled, eliminating the need to pull wires through conduit
Frequently Asked Questions
Q: What size breaker is used with 10/3 MC Cable?
A: Typically a 30-amp breaker, but always confirm with local electrical code and application requirements.
Q: Can I use 10/3 MC Cable outdoors?
A: Standard versions are for dry locations. Use a PVC-jacketed or MC-HL variant for wet/outdoor areas.
Q: What’s the difference between 10/3 and 10/2 MC Cable?
A: 10/3 includes a neutral wire for 120/240V applications. 10/2 has only two hot wires and ground, for 240V-only use.
