The conductor is manufactured from oxygen-free plain copper to provide excellent conductivity for demanding low-voltage DC electrical systems.

As a result, this cable is an excellent choice for customers who want quality Australian-made copper cable rather than undersized or copper-clad alternatives.

⚡ Heavy-Duty 246A Current Rating

The 0 B&S cable is rated up to approximately:

246A at 30°C

This makes it well suited to substantial high-current DC applications such as:

• Inverter systems
• Lithium battery banks
• Battery interconnects
• Auxiliary battery systems
• Starter circuits
• Main battery feeds
• High-current power distribution
• Bus bar connections

Importantly, the actual safe current capacity depends on installation conditions.

Cable bundling, ambient temperature, cable length and installation method can all affect allowable current.

🔋 49mm² Oxygen-Free Copper Conductor

With a nominal conductor area of 49.00mm², 0 B&S provides a significant amount of copper for demanding battery systems.

For comparison across the Razorback DC TYCAB range:

• 6 B&S – 13.50mm² / 103A
• 4 B&S – 20.26mm² / 135A
• 2 B&S – 32.07mm² / 188A
• 0 B&S – 49.00mm² / 246A
• 00 B&S – 64.15mm² / 292A
• 000 B&S – 83.19mm² / 335A

Therefore, 0 B&S sits perfectly between 2 B&S and 00 B&S for installations requiring substantial current capacity without stepping all the way up to the larger cable sizes.

🧵 608-Strand Flexible Copper Construction

The conductor consists of:

608 strands × 0.32mm oxygen-free copper

The large number of fine copper strands provides improved flexibility compared with a solid conductor of equivalent cross-sectional area.

This is especially useful when routing cable through:

• 4WD canopies
• Engine bays
• Battery compartments
• Caravans
• Camper trailers
• Inverter installations
• Boats
• Off-grid electrical systems

Furthermore, flexible construction makes heavy battery cable easier to bend and position around electrical equipment.

🔌 Ideal for Inverter Wiring

Inverters can draw substantial current from a 12V battery bank.

Therefore, correctly sized battery cable is critical for maintaining voltage and reducing electrical losses.

0 B&S cable is ideal for appropriately designed:

• Pure sine wave inverter systems
• Battery-to-inverter connections
• Fuse-to-inverter connections
• Bus bar-to-inverter wiring
• High-current DC equipment

Always select cable size according to inverter current, cable length, system voltage and the inverter manufacturer's requirements.

🔋 Excellent for Lithium Battery Systems

Modern LiFePO4 batteries can deliver substantial continuous current.

Consequently, the cables connecting the battery, fuse protection, bus bars and inverter must be capable of carrying the required load.

0 B&S cable is ideal for:

• Lithium auxiliary batteries
• Parallel battery banks
• Battery linking cables
• Battery-to-bus-bar connections
• Main battery feeds
• High-current distribution systems

Correctly sized copper cable helps minimise voltage drop and resistance throughout the system.

🚙 Perfect for 4WD & Ute Canopy Systems

Modern touring vehicles can contain substantial electrical equipment.

The Razorback 0 B&S Battery Cable is ideal for systems incorporating:

• Lithium batteries
• Inverters
• DC power distribution
• Bus bars
• Fuse holders
• Battery isolators
• Auxiliary battery systems
• High-current accessories

Additionally, the flexible conductor construction makes cable routing easier through ute canopies and custom electrical panels.

🏕️ Caravan & Camper Applications

Caravans and camper trailers increasingly use higher-capacity lithium batteries and larger electrical loads.

0 B&S cable is ideal for connecting:

• Battery banks
• Inverters
• Main fuse protection
• Bus bars
• Battery isolation switches
• Chargers
• DC distribution systems

As a result, it is an excellent choice for serious touring and off-grid caravan builds.

☀️ Solar & Off-Grid Battery Systems

Large solar and off-grid battery systems also require quality high-current DC wiring.

Typical applications include:

• Battery-to-inverter connections
• Battery-bank linking
• Battery-to-bus-bar wiring
• Main DC distribution
• High-current fuse connections
• Solar battery storage systems

Reducing cable resistance is particularly important in low-voltage DC systems because even a small voltage drop can affect equipment performance.

🚗 Starter & Automotive Applications

0 B&S is also suitable for appropriately designed battery and starter wiring.

Potential applications include:

• Starter motor circuits
• Vehicle battery cables
• Earth cables
• Commercial vehicles
• Machinery
• Heavy auxiliary circuits

Always follow the equipment or vehicle manufacturer's required cable specifications.

🔴⚫ Available in Red or Black

This cable is designed for low-voltage automotive and battery applications and is not intended for connection to mains power.

📉 Low Electrical Resistance

The 0 B&S conductor has an electrical resistance of approximately:

0.4Ω per kilometre at 20°C

Low resistance is especially important in high-current DC circuits because excessive resistance contributes to:

• Voltage drop
• Power loss
• Cable heating
• Reduced inverter performance
• Poor charging performance

Using quality oxygen-free copper cable helps reduce these losses.

📏 Approx. 12.7mm Outside Diameter

The nominal outside diameter of the cable is approximately:

12.7mm

This is useful when selecting:

• Cable glands
• Conduit
• Cable clamps
• Protective sleeving
• Routing holes
• Cable management hardware

Allow suitable clearance when routing cable through panels or protective conduit.

🔩 Cable Lug Selection

0 B&S cable requires correctly sized copper cable lugs.

Always match the lug to:

• 49mm² conductor area
• Required terminal stud size
• Crimping tool
• Connected equipment

Depending on the lug manufacturer's sizing, a suitable lug around the 50mm² conductor range will generally be required.

Razorback DC stocks copper cable lugs in multiple cable and stud-hole sizes.

✂️ Professional Cable Preparation

For a reliable high-current connection, use suitable cable preparation tools.

Recommended equipment includes:

• Heavy-duty ratchet cable cutter
• Cable lug crimping tool
• Copper cable lugs
• Adhesive-lined heat shrink
• Battery terminal covers
• Protective conduit

A clean cable cut and correctly crimped lug are essential for dependable electrical performance.

🔥 Correct Fuse Protection

High-current positive battery cables should be protected with an appropriately selected fuse or circuit breaker.

Suitable protection may include:

• MEGA fuses
• ANL fuses
• T-Class fuses
• High-current circuit breakers

Fuse size should be chosen to protect the cable and complete electrical circuit, while also complying with equipment manufacturer requirements.

⚠️ Current Rating & Derating

The stated 246A rating applies at 30°C under specified conditions.

Actual allowable current can be reduced by:

• Higher ambient temperatures
• Multiple cables bundled together
• Enclosed installation
• Cable routing
• Installation conditions

Therefore, appropriate derating should be considered when designing high-current systems.
