Southwire 14-4C-50 Shielded Mini Split Cable 14AWG 4C 50ft

Product Description

The SOUTHWIRE 14-4C-50 SHIELDED is a shielded multi-conductor cable engineered for mini split system wiring applications. It runs 50 feet in length and features a 14 AWG, 4-conductor configuration with integrated shielding to reduce electromagnetic interference. This cable is designed for the low-voltage communication and power wiring that connects the indoor air handler to the outdoor condensing unit in ductless mini split systems. HVAC technicians and installers rely on shielded cable in these runs to maintain clean signal transmission and comply with manufacturer wiring requirements.

This cable is suited for residential and light commercial ductless mini split installations where a single 50-foot run covers the distance between indoor and outdoor units. The 4-conductor construction supports systems requiring both power and communication wiring in one cable run. The shielding layer is particularly important in installations near other electrical runs or in environments with elevated electrical noise, helping maintain reliable communication between the indoor and outdoor units.

Key Features

• 14 AWG 4-conductor construction supports combined power and communication wiring in a single cable
• Integrated shielding reduces electromagnetic interference for reliable signal transmission
• 50-foot length suits most single-story and two-story residential mini split installations
• Designed for low-voltage wiring connections between indoor air handler and outdoor condensing unit
• Pre-cut to length to reduce job-site waste and simplify rough-in work

Compatibility

Designed as a wiring solution for ductless mini split systems requiring shielded 14 AWG 4-conductor cable between the indoor and outdoor units. Verify the system manufacturer's wiring specifications before installation to confirm conductor count and gauge requirements.

Installation Notes

Installation should be performed by a licensed HVAC technician or electrician in accordance with NEC requirements and the mini split manufacturer's wiring diagram. Disconnect and lock out power at both the indoor and outdoor units before making any wiring connections. Route the cable to avoid sharp bends, pinch points, and contact with refrigerant lines where possible. Proper termination of the shield drain wire per the equipment manufacturer's instructions is important for effective EMI protection.
