Southwire MC-PCS Duo Power and Control/Signal Cable User Manual

1. Introduction

This manual provides essential information for the proper installation, use, and maintenance of the Southwire 12/2 Solid 16/2 Solid x 250 ft. MC-PCS Duo Power and Control/Signal Cable. Please read this manual thoroughly before beginning any work to ensure safe and effective operation.

The Southwire MC-PCS Duo cable is designed for combining power/lighting circuits with Class 2 or Class 3 signal or control circuits within a single cable assembly. This product meets the National Electrical Code (NEC) and UL listing requirements for such applications.

2. Important Safety Information

WARNING: Risk of Electric Shock. Installation should only be performed by qualified personnel in accordance with all applicable national and local electrical codes.

• Always disconnect power at the circuit breaker or fuse box before installing or servicing electrical wiring.
• Ensure all connections are secure and properly insulated to prevent short circuits and electrical hazards.
• Do not exceed the specified voltage and current ratings for this cable.
• Protect the cable from physical damage during and after installation.
• Wear appropriate personal protective equipment (PPE), including safety glasses and insulated gloves, when working with electrical systems.
• Consult local building codes and regulations for specific requirements regarding cable installation.

3. Product Overview

The Southwire MC-PCS Duo cable integrates both power and control/signal conductors within a single interlocked armor. This design simplifies installation and reduces the need for multiple cable runs.

Visible conductors include a blue, white, black, and green wire, indicating both power and control/signal components.

3.1 Key Features and Applications

• Integrated Design: Combines 12/2 Solid power conductors and 16/2 Solid control/signal conductors in one cable.
• Versatile Use: Suitable for branch power distribution in commercial, industrial, institutional, and multi-residential buildings.
• Lighting and Control: Ideal for power, lighting, control, and signal circuits, including luminary applications with 0-10V dimming in LED lighting systems.
• Installation Flexibility: Can be fished or embedded in plaster, and used in both concealed or exposed installations.
• Code Compliant: Meets NEC and UL listing requirements for combining different circuit types.

4. Installation Instructions

Follow these general guidelines for installing the Southwire MC-PCS Duo cable. Always refer to local electrical codes and the NEC for specific requirements.

4.1 Pre-Installation Checklist

• Verify that the cable type and size are appropriate for the intended application and load requirements.
• Ensure all necessary tools and connectors are available.
• Confirm that power to the installation area is safely disconnected.

4.2 Installation Steps

1. Route the Cable: Carefully route the MC-PCS Duo cable along the intended path, ensuring it is protected from sharp edges, excessive bending, and potential damage.
2. Secure the Cable: Secure the cable using appropriate straps, clamps, or hangers at intervals compliant with local codes and manufacturer recommendations.
3. Terminate Conductors:
   • Carefully strip the outer armor and insulation from the conductors at the termination points.
   • Connect the 12/2 Solid power conductors (typically black, white, and bare ground) to the power circuit terminals.
   • Connect the 16/2 Solid control/signal conductors (typically blue and green, or as per specific application) to the control or signal circuit terminals.
   • Ensure all connections are tight and secure.
4. Grounding: Ensure proper grounding of the cable armor and all connected equipment as required by code.
5. Testing: After installation, perform continuity and insulation resistance tests to verify proper wiring and absence of faults before restoring power.
6. Restore Power: Once all checks are complete and safe, restore power to the circuit.

5. Operating Principles

The Southwire MC-PCS Duo cable functions as a conduit for both electrical power and low-voltage control/signal transmissions. Once properly installed and connected to a power source and control devices, it facilitates the intended electrical and communication functions.

• Power Conductors: The 12/2 Solid conductors deliver electrical power to connected loads, such as lighting fixtures.
• Control/Signal Conductors: The 16/2 Solid conductors transmit low-voltage signals, commonly used for dimming controls (e.g., 0-10V dimming) or other control applications.
• Integrated Functionality: The cable's design allows for simultaneous power delivery and signal transmission, streamlining wiring for systems requiring both.

6. Maintenance

The Southwire MC-PCS Duo cable is designed for long-term reliability with minimal maintenance. However, periodic inspection is recommended to ensure continued safe operation.

• Visual Inspection: Periodically inspect exposed sections of the cable for any signs of physical damage, such as cuts, abrasions, or crushing.
• Connection Integrity: Ensure that all connections remain tight and free from corrosion.
• Environmental Protection: Verify that the cable is not exposed to conditions beyond its rated environmental specifications (e.g., extreme temperatures, excessive moisture) unless specifically designed for such environments.
• Cleaning: If necessary, clean the exterior of the cable with a dry cloth. Do not use harsh chemicals or abrasive materials.

7. Troubleshooting

This section addresses common issues that may arise during or after the installation of the MC-PCS Duo cable. Always ensure power is disconnected before attempting any troubleshooting steps involving live circuits.

If issues persist after following these steps, contact a qualified electrician or Southwire customer support.
