MAXI Fuse Holder with 8 AWG Cable – 12V Inline Battery Fuse Holder

Razorback DC MAXI Fuse Holder with 8 AWG Cable – 12V Inline Battery & Accessory Fuse Holder

Protect your 12V electrical wiring with the Razorback DC MAXI Fuse Holder, supplied with heavy-duty 8 AWG cable for reliable inline circuit protection in automotive, 4WD, caravan, camping and auxiliary battery systems.

Designed to accept standard MAXI blade fuses, this inline fuse holder provides a simple way to protect higher-current circuits supplying accessories, Anderson plugs, compressors, fridges, lighting, battery equipment and other 12V loads.

Because the fuse holder is supplied with 8 AWG cable, it is particularly well suited to medium-to-high-current automotive circuits where heavier wiring is required.

Simply select a suitable MAXI fuse rating for the cable, connected equipment and electrical system.

⚡ Heavy-Duty 8 AWG Cable

One of the key advantages of the Razorback DC MAXI Fuse Holder is the supplied 8 AWG power cable.

8 AWG cable provides a substantially larger conductor than lighter accessory wiring and is commonly used for moderate-to-higher-current automotive circuits.

Therefore, the fuse holder is suitable for applications such as:

• Auxiliary power feeds
• Anderson plug circuits
• Air compressors
• 12V fridges and freezers
• Battery box wiring
• Accessory distribution
• Lighting systems
• Pumps
• Charging circuits where appropriately rated
• General high-current 12V accessories

Importantly, the safe current capability of the complete circuit depends on cable construction, cable length, installation conditions and temperature.

🛡️ Inline Circuit Protection

A fuse is designed to protect the wiring, not simply the accessory connected to it.

If a positive cable becomes damaged or shorted to earth, the battery can deliver extremely high fault current.

Therefore, installing suitable fuse protection close to the power source is an important part of a properly designed 12V electrical system.

The Razorback MAXI Fuse Holder allows a replaceable MAXI blade fuse to be installed directly into the supply cable.

🔥 Why Fuse Protection Matters

Without adequate fuse protection, an electrical fault can cause:

• Excessive cable heating
• Melted insulation
• Damage to electrical equipment
• Damage to vehicle wiring
• Increased fire risk

For this reason, the fuse rating should always be selected to protect the 8 AWG cable and connected circuit.

Do not simply install the largest fuse that physically fits the holder.

🔌 Compatible with MAXI Blade Fuses

The holder is designed to accept standard MAXI automotive blade fuses.

Razorback DC MAXI Blade Fuses are available in multiple ratings, including:

• 20A
• 30A
• 40A
• 50A
• 60A
• 70A
• 80A
• 100A

However, the correct fuse rating depends on the cable, load and complete electrical system.

Therefore, always choose the fuse according to the actual circuit requirements.

🚙 Ideal for 4WD Electrical Systems

The Razorback MAXI Fuse Holder is an excellent choice for 4WD and ute canopy electrical installations.

Typical applications include:

• Dual-battery systems
• Anderson outlets
• Auxiliary power feeds
• Fridges
• Air compressors
• Pumps
• Lighting
• Canopy power systems
• Battery boxes
• Camping accessories

Furthermore, its inline design makes it easy to position fuse protection near the battery or power distribution point.

🛻 Ute Canopy & Touring Applications

Modern 4WD canopy systems often contain multiple accessories powered from an auxiliary battery.

For example, a canopy setup may contain:

• Lithium battery
• AGM battery
• DC-DC charger
• Fridge
• Compressor
• Anderson outlets
• Lighting
• USB chargers
• Water pumps

The MAXI Fuse Holder can be incorporated into individual circuits to provide appropriate protection for selected equipment.

🏕️ Caravan & Camper Applications

Caravan and camper electrical systems also benefit from properly fused accessory circuits.

Suitable applications include:

• Fridge power
• Pumps
• Lighting circuits
• Auxiliary outlets
• Battery systems
• Camping accessories
• Anderson connections
• General 12V power feeds

As a result, the Razorback MAXI Fuse Holder is a practical addition to both new installations and existing electrical upgrades.

🔋 Battery & Auxiliary Power Systems

The fuse holder can be used with compatible battery systems including:

• LiFePO4 lithium batteries
• AGM batteries
• Gel batteries
• Starting batteries
• Auxiliary battery systems

Battery chemistry does not determine the fuse rating.

Instead, the fuse should be selected according to:

• Cable capacity
• Connected equipment
• Maximum expected current
• Installation conditions

🔌 Great for Anderson Plug Circuits

MAXI fuses are commonly used in moderate-current Anderson plug circuits.

The Razorback holder can therefore be used to protect wiring feeding:

• 50A Anderson-style outlets
• Portable fridges
• Battery chargers
• Camping equipment
• Portable battery boxes
• Auxiliary power accessories

Always ensure the fuse rating is appropriate for both the cable and connected equipment.

🔧 Simple Inline Installation

Installation is straightforward when incorporated into a properly designed circuit.

A typical installation may look like:

Battery Positive → MAXI Fuse Holder → Accessory / Power Distribution

For the best protection, position the fuse holder as close to the battery or power source as practical.

This helps minimise the length of unfused positive cable.

🔥 Correct Fuse Selection

Selecting the correct fuse rating is critical.

The fuse should generally be sized to protect the cable while still allowing normal equipment operation.

Consider:

• Maximum equipment current
• Cable size
• Cable length
• Installation temperature
• Cable bundling
• Voltage drop
• Manufacturer requirements

Consequently, the correct fuse may vary between different installations even when the same fuse holder is used.

⚠️ 8 AWG Does Not Automatically Mean 100A

Although MAXI fuses are available up to 100A, that does not automatically mean an 8 AWG circuit should use a 100A fuse.

The safe current capacity of 8 AWG cable varies depending on:

• Conductor construction
• Insulation rating
• Cable length
• Ambient temperature
• Installation method

Therefore, select the fuse according to the actual cable specification and application.

🧰 Installation Tips

For a reliable installation:

1. Disconnect the battery before working on the circuit.
2. Position the fuse holder near the positive power source.
3. Use secure electrical connections.
4. Protect cable from sharp edges.
5. Keep wiring away from exhaust and excessive heat.
6. Secure the cable against vibration and movement.
7. Select the correct MAXI fuse rating.
8. Confirm polarity before reconnecting power.

Additionally, use conduit, sleeving or grommets where the wiring passes through metal panels or exposed areas.
