Which Bulk Cable Do I Need?

Not sure which construction makes the most sense? Start here.

Building battery or inverter cables? Choose Battery Cable for high-current DC connections between batteries, inverters, busbars and other DC equipment.

Need heavy cable that bends easily? Choose Welding Cable when maximum flexibility is important, especially in RVs, vans, boats and tight equipment compartments.

Running portable AC power or equipment? Choose SOOW Cable for flexible multi-conductor power applications, portable equipment, generators, tools and demanding environments.

Running signals, controls or low-voltage wiring? Look at our Belden-equivalent cable for commercial signal, control, security, communications and other low-voltage applications.

Compare Your Options

Battery Cable vs. Welding Cable vs. SOOW

Each cable type has advantages. The best choice depends on what you are powering and how the cable will be installed.

Cable Type	Best For	Key Advantage	Typical Applications
Battery Cable	High-current DC wiring	Heavy-duty copper power conductor	Batteries, inverters, solar, automotive, RV & marine
Welding Cable	High-current applications requiring flexibility	Very flexible, durable EPDM construction	Welding leads, battery systems, RVs, vans, boats & equipment
SOOW Cable	Flexible multi-conductor power	Heavy-duty portable cord construction	Generators, tools, portable power, RV, marine & industrial equipment
Belden Equivalent	Signal and control wiring	Application-specific commercial cable	Controls, security, communications, AV & low-voltage systems

Bulk Cable FAQ

Frequently Asked Questions

What is the difference between battery cable and welding cable?

Both can be used for high-current electrical applications, but welding cable is designed to be especially flexible. That makes it an excellent choice when a heavy cable must bend around corners or route through tight spaces. Battery cable is an excellent choice for traditional battery, inverter and DC power connections.

Is Spartan Power cable made from real copper?

Yes. Spartan Power bulk battery cable and welding cable use 100% pure copper conductors rather than copper-clad aluminum (CCA).

What size battery cable should I use for my inverter?

Cable size depends on inverter wattage, DC system voltage, cable length, expected current and the requirements of the equipment manufacturer. Always follow the inverter manufacturer's cable-size and overcurrent-protection recommendations. If you need help selecting cable for an inverter system, contact Inverters R Us.

When should I use SOOW cable?

SOOW is a heavy-duty flexible multi-conductor cord commonly used for portable power, industrial equipment, generators, tools and other applications where durability and flexibility are important. Installation requirements vary by application, so permanent wiring should always comply with applicable electrical codes.

Can welding cable be used for battery cables?

Welding cable is commonly selected for battery and high-current DC applications where flexibility is especially important. The correct gauge, insulation, termination method, current capacity and equipment requirements still need to be considered for the specific installation.

What are Belden-equivalent cables used for?

Belden-equivalent electronic cables are generally intended for signal, communication, control and other low-voltage applications rather than high-current battery connections. Inverters R Us offers equivalents for several commonly used Belden cable constructions.
