Installation and Setup

Proper installation is crucial for the safe and effective operation of your fuse box. Follow these steps carefully.

Mounting:

1. Select Location: Choose a dry, secure location away from direct heat, moisture, and excessive vibration. Ensure sufficient space for wiring and access to the fuse box.
2. Mark Mounting Holes: Use the fuse box as a template to mark the positions for the mounting holes. Refer to the "Product Dimension" image for precise measurements.
3. Drill Holes: Drill appropriate pilot holes for your mounting screws.
4. Secure Fuse Box: Fasten the fuse box securely using suitable screws (not included) through the designated mounting holes.

Wiring Guide:

The fuse box is designed for a single power input and 10 circuit outputs. Always disconnect the power source before wiring.

1. Power Input: Connect the positive (+) power source (e.g., battery positive terminal) to the #10-33 stud on the fuse box. Ensure a secure connection.
2. Circuit Outputs: Connect the positive (+) wire from each accessory or device to one of the .250 inch male quick disconnect terminals. Each terminal corresponds to a fuse slot.
3. Grounding: Ensure all devices connected to the fuse box have a proper ground connection to the vehicle or marine chassis. The fuse box itself does not provide ground connections for the individual circuits.
4. Fuse Installation: Insert the appropriate ATO/ATC blade fuse into each circuit slot according to the current requirements of the connected device. Refer to the included fuse assortment and DIY sticker for common amperage ratings.
5. Labeling: Use the provided DIY stickers to label each circuit for easy identification of connected devices.

Note: Always use fuses with the correct amperage rating for your devices to prevent damage or fire. Consult a professional if you are unsure about wiring procedures.

Operation

The BUNKER INDUST 10-Way Blade Fuse Box is designed for straightforward operation and quick fault identification.

LED Indicator for Blown Fuses:

Each fuse slot is equipped with a red LED indicator. If a fuse blows due to an overcurrent condition or short circuit, the corresponding red LED light next to that fuse will illuminate. This feature allows for immediate identification of the problematic circuit without the need for a multimeter or visual inspection of each fuse.

Replacing a Blown Fuse:

1. Identify Blown Fuse: Locate the fuse slot with the illuminated red LED.
2. Remove Protective Cover: Gently unclip and remove the clear plastic protective cover.
3. Remove Blown Fuse: Carefully pull out the blown fuse from its slot. A fuse puller (not included) may be helpful.
4. Install New Fuse: Insert a new ATO/ATC blade fuse of the exact same amperage rating into the empty slot. Using a fuse with a higher rating can lead to electrical system damage or fire.
5. Replace Protective Cover: Securely clip the clear plastic cover back into place.

Maintenance

Regular maintenance ensures the longevity and reliable performance of your fuse box.

• Keep Clean: Periodically wipe down the fuse box and its cover with a dry, clean cloth to remove dust and debris. Avoid using harsh chemicals or abrasive cleaners.
• Check Connections: Annually, or if experiencing intermittent issues, inspect all wiring connections to ensure they are tight and free from corrosion. Pay particular attention to the main power input stud.
• Inspect Fuses: While the LED indicator helps, a visual inspection of fuses during routine checks can identify any signs of overheating or damage to the fuse itself or its terminals.
• Cover Integrity: Ensure the protective cover is securely clipped and free from cracks or damage to maintain its splash and dust-proof properties.
