🔌 Choose M6, M8 or M10 Studs

Different electrical equipment uses different cable lug hole sizes.

For this reason, the Razorback 6-Gang Bus Bar is available in three terminal configurations:

• M6 – 6mm studs
• M8 – 8mm studs
• M10 – 10mm studs

Choose the version that matches the ring terminals and cable lugs used throughout your electrical system.

Importantly, stud size alone does not determine the safe current capacity of an electrical system. Cable size, lug size, bus bar construction, circuit protection and connected equipment must all be considered when designing a high-current installation.

🔴⚫ Positive & Negative Bus Bars Included

Each set includes two separate distribution bars:

1 × Positive Bus Bar

and

1 × Negative Bus Bar

This allows both sides of the DC electrical system to be organised neatly.

As a result, multiple circuits can share central positive and negative connection points instead of stacking numerous terminals directly onto battery posts.

🔢 Six Connection Points Per Bar

Each bus bar provides six terminal studs, giving you plenty of connection points for expanding or organising an electrical system.

Potential connections include:

• Battery cables
• DC-DC chargers
• Solar controllers
• Inverters
• Fuse boxes
• Battery chargers
• Auxiliary circuits
• Anderson outlets
• Accessory power systems
• Battery monitoring equipment

Therefore, the 6-gang design is particularly useful for larger electrical installations with multiple high-current or auxiliary circuits.

🔋 Cleaner Battery System Wiring

Connecting numerous cables directly to battery terminals can quickly create a crowded and difficult-to-service installation.

A dedicated bus bar provides a central distribution point between the battery and connected equipment.

Consequently, wiring can become:

• Cleaner
• Easier to organise
• Easier to inspect
• Easier to service
• Easier to expand
• More professional in appearance

This is particularly beneficial in modern lithium battery systems where multiple chargers, inverters and distribution circuits may all require battery connections.

🚙 Ideal for 4WD Electrical Systems

The Razorback DC 6-Gang Bus Bar Set is an excellent addition to larger 4WD and ute canopy electrical systems.

Use it to organise connections for:

• Auxiliary batteries
• DC-DC chargers
• Inverters
• Fuse boxes
• Solar controllers
• Anderson outlets
• Fridges and freezers
• Lighting
• Compressors
• Accessory power

Furthermore, mounting the bus bars inside a dedicated electrical panel or canopy enclosure can produce a much cleaner installation.

🛻 Perfect for Ute Canopy Builds

Modern canopy electrical systems can contain a substantial number of high-current components.

For example, one installation may include:

• Lithium battery
• DC-DC charger
• Solar controller
• Inverter
• Fuse panel
• Battery monitor
• Fridge
• Lighting
• Anderson connections

Rather than stacking all of these connections directly onto the battery terminals, a positive and negative bus bar pair allows the system to be distributed more logically.

🏕️ Caravan & Camper Trailer Applications

The 6-Gang Bus Bar Set is also ideal for caravan, camper trailer and motorhome electrical systems.

Suitable connections may include:

• House batteries
• Solar charging
• DC-DC charging
• AC battery chargers
• Inverters
• Fuse panels
• Water pumps
• Refrigeration
• Lighting systems
• General 12V accessories

Additionally, the six-terminal layout leaves room for future electrical upgrades.

☀️ Solar & Off-Grid Systems

Bus bars are particularly useful in solar and off-grid battery installations where several components need access to the same battery bank.

Potential connections include:

• Lithium battery banks
• AGM battery banks
• MPPT solar controllers
• Battery chargers
• Inverters
• Fuse protection
• Monitoring equipment
• DC loads

As a result, the bus bars can become a central connection point within a properly designed off-grid DC system.

🌊 Marine Electrical Systems

The Razorback 6-Gang Bus Bar Set can also be incorporated into suitable boat and marine electrical installations.

Typical uses include:

• Battery systems
• Navigation equipment
• Pumps
• Lighting
• Electronics
• Charging equipment
• Auxiliary circuits

However, marine installations should always use appropriate cable, terminals, circuit protection and installation practices for the operating environment.

⚡ Suitable for 12V & 24V Systems

The bus bars are suitable for many 12V and 24V DC electrical systems.

Applications include:

• 4WDs
• Caravans
• Camper trailers
• Motorhomes
• Boats
• Solar systems
• Battery banks
• Commercial vehicles
• Custom automotive projects

Always ensure the complete electrical system is designed around the expected maximum current.

🔧 Secure Stud Connections

Each connection point uses a threaded stud, allowing compatible ring terminals and cable lugs to be securely fastened.

This provides a robust connection method for correctly terminated battery and power cables.

For the best results:

• Select the correct lug hole size
• Use quality copper cable lugs
• Use correctly sized cable
• Tighten terminals securely
• Avoid overtightening
• Protect exposed positive connections from accidental short circuits

🔥 Correct Cable & Fuse Selection

A bus bar does not replace circuit protection.

Therefore, individual circuits should be appropriately protected using suitable:

• MIDI fuses
• MEGA fuses
• MRBF fuses
• ANL fuses
• Circuit breakers

Fuse selection should be based primarily on the cable and equipment being protected.

Similarly, cable size should be selected according to:

• Maximum current
• Cable length
• Acceptable voltage drop
• Installation environment
• Equipment requirements

🧰 Installation

For a typical battery distribution installation:

Battery → Main Fuse → Positive Bus Bar → Individual Circuits

while the negative side may use:

Battery Negative → Negative Bus Bar → Individual Equipment Grounds

For reliable installation:

1. Mount both bus bars securely.
2. Keep positive and negative distribution clearly identified.
3. Use correctly sized battery cable.
4. Crimp cable lugs using an appropriate tool.
5. Install suitable fuse protection.
6. Keep exposed conductive components protected.
7. Secure all cables against vibration and movement.
8. Confirm polarity before connecting the battery.

🔩 Selecting the Correct Stud Size

Choose the bus bar primarily according to the lug hole size required by your cables and connected equipment.

M6 – 6mm Stud

Ideal where your cable lugs and ring terminals use an approximately 6mm mounting hole.

Commonly useful for:

• Accessory circuits
• Chargers
• Fuse panels
• Smaller cable terminations
• Compact electrical systems

M8 – 8mm Stud

The M8 option provides an excellent general-purpose connection size for many automotive and battery installations.

Suitable for:

• Battery cables
• DC-DC chargers
• Fuse systems
• Solar equipment
• Medium-to-heavy cable terminations

M10 – 10mm Stud

Choose the M10 option when your system uses larger 10mm lug holes.

This is particularly useful for:

• Large battery cables
• Inverter cabling
• Battery banks
• High-current distribution systems
• Heavy-duty electrical installations

Again, the selected stud diameter should match your cable lug requirements rather than being used by itself as an indication of electrical current capacity.

  ⚠️ Current Rating Note

  The safe current capacity of an electrical installation depends on more than terminal stud diameter.

  Always consider:

  • Bus bar construction
  • Cable size
  • Cable length
  • Cable lug rating
  • Fuse protection
  • Connection quality
  • Maximum connected load

  Do not select an M6, M8 or M10 bus bar solely on the assumption that a larger stud automatically provides a specific amperage rating.
