Southwire 56370602 Submersible Pump Cable 12AWG 3C 600V 500ft

Product Description

The SOUTHWIRE 56370602 is a 12 AWG, 3-conductor twisted submersible pump cable rated for 600 volts and designed for direct burial and underwater installations in residential and light commercial water systems. Built on solid bare copper conductors with PVC insulation, it delivers reliable power transfer to submersible well pumps and similar loads. The cable ships as a 500-foot coil and includes a ground conductor. It carries UL 83 and RoHS approvals and is rated for temperatures from -40 to 75 degrees C, making it suitable for cold-climate installations where freeze exposure is a concern.

This cable is used primarily in well pump installations where the power supply must run from the pressure tank area down through a well casing to a submersible pump motor. It is also applicable in sump and cistern pump applications requiring a rated, code-compliant pump drop cable. The twisted conductor geometry helps reduce voltage drop and electrical noise across longer runs. Licensed electricians and pump service technicians are the primary installers of this cable type.

Key Features

• 12 AWG solid bare copper conductors for low-resistance power delivery
• 600-volt rating suitable for standard single-phase pump circuits
• Twisted cable construction minimizes voltage drop on deep-well runs
• PVC insulation resists acid, alkalis, oil, gas, water, abrasion, and flame
• Includes ground conductor for code-compliant installations
• UL 83 listed and RoHS compliant
• 500-foot coil ready for job-site deployment

Compatibility

Designed as a standard submersible pump drop cable for residential and light commercial well pump systems requiring 12 AWG, 3-conductor, 600-volt rated cable with ground.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 230 and any applicable local codes governing pump wiring. Disconnect and lock out power at the panel before handling any conductors or making connections at the pump or pressure switch. Avoid sharp bends at the well casing entry point that could damage the PVC insulation over time. Verify conductor size and voltage rating against the pump motor nameplate before pulling the drop cable.
