Power Cable 4 Gauge Red 125ft Roll

The QUICKCAR Racing Products Power Cable 4 Gauge Red 125ft Roll (Part No. 57-092) is a professional-grade battery cable designed for marine electrical systems, racing applications, and high-power DC distribution. The 4-gauge copper conductor delivers the current-carrying capacity required for reliable engine starting and auxiliary power on mid-to-large boats, offshore fishing vessels, and high-performance racing setups where voltage drop and heat generation must be minimized over extended runs.

At 4 gauge, this cable provides roughly 55 amps of continuous ampacity—sufficient for starter motors, battery chargers, and primary power distribution in systems up to 48 volts. The 125-foot roll length accommodates installations in larger vessels or allows technicians to cut and terminate multiple shorter runs from a single spool. Bare copper construction ensures superior electrical conductivity and corrosion resistance compared to tinned alternatives, though marine environments require proper insulation and routing to prevent salt spray damage. The red jacket facilitates positive circuit identification and simplifies troubleshooting during installation and maintenance.

This cable suits boaters upgrading from lighter-gauge feeder wires, racers installing auxiliary electrical systems, and technicians designing shore-power charging stations and battery isolator setups. It works equally well as a main battery positive feed or dedicated power distribution conductor where voltage regulation and minimal resistive loss are priorities. The 125-foot bulk roll is ideal for shops and service facilities that terminate cables to specification rather than relying on pre-made assemblies with fixed connectors.

QUICKCAR Racing Products specializes in automotive and marine electrical components trusted by engine builders and fabricators. Proper cable sizing—verified by wire gauge and ampacity rating—is critical for safety and system reliability; this 4-gauge specification is widely recognized in marine standards and racing industry practice as the benchmark for mid-power distribution systems.
