Southwire 150C-2 Booster Cable Clamp 150 Amp

Product Description

The SOUTHWIRE 150C-2 is a 150-amp booster cable clamp set designed for jump-starting vehicles and other high-current DC applications. Sold as a pair — one black, one red — these clamps feature copper-plated steel construction for reliable conductivity and a secure grip on battery terminals. The 150-amp rating handles the current demands of most passenger vehicles and light commercial equipment. Electricians, automotive technicians, and fleet maintenance professionals keep these clamps on hand for battery service work and emergency starting situations.

This clamp pair is suited for use with standard booster cable assemblies in automotive, light truck, and equipment battery service. The copper-plated steel contact surfaces make solid electrical contact across a range of battery terminal sizes. The black and red color coding follows standard polarity convention, reducing the risk of reversed connections during jump-start procedures.

Key Features

• 150-amp rated for high-current jump-start applications
• Copper-plated steel connection material for good conductivity and durability
• Sold as a matched pair — one black (negative) and one red (positive)
• Standard polarity color coding for safe, correct connection
• Compact and lightweight at approximately 1 pound per pair

Compatibility

Designed as a replacement or service clamp pair compatible with standard booster cable assemblies rated at or below 150 amps.

Installation Notes

Always connect and disconnect booster clamps with both vehicles off to reduce arc and spark risk. Attach the positive (red) clamp first, then the negative (black) clamp, following standard jump-start sequencing. Inspect clamp jaws and cable connections for corrosion or mechanical damage before use. This work is typically performed by automotive technicians or electricians familiar with DC battery systems.
