Attwood Marine ATO/ATC Fuse Holder, 30A, 12 AWG, Watertight

Overview

The Attwood Marine 14348-6 is an inline ATO/ATC fuse holder for marine electrical circuits that need a protected blade-fuse connection in a space exposed to spray, moisture, and vibration.

It accepts ATO/ATC fuses up to 30 amps and comes with 12-gauge wire leads for splice-in installation. The housing is watertight and weatherproof, which makes it a practical choice for accessory circuits where the fuse holder may sit behind a helm, inside a console, under a deck, or in another area that does not stay completely dry.

This is the kind of fuse holder used when you need a single protected circuit for electronics, lighting, pumps, or other onboard equipment that calls for an inline blade fuse. It is a straightforward replacement when the circuit already uses ATO/ATC fuses, and it also works well when adding a new fused feed close to the power source.

Key features

• Inline holder for standard ATO/ATC blade fuses
• Rated for fuse sizes up to 30 amps
• 12-gauge wire leads for splice-in wiring
• Watertight and weatherproof body for exposed marine installations
• Heavy-duty construction that suits areas where wiring sees regular vibration
• Fuse is not included

Installation and setup

The 12 AWG leads make this holder easy to add into an existing run or into a new accessory feed. For boat wiring, it fits best where you want the fuse close to the source of power while still keeping the fuse accessible for inspection and replacement.

Before installation, match the fuse type and fuse rating to the equipment and wire size already on the circuit. This holder is for ATO/ATC blade fuses only, so it is worth checking the existing fuse style before ordering a replacement.

Compatibility and fit

This fuse holder is a good match for boats that already use ATO/ATC blade fuses and need an inline format rather than a panel block or breaker. The 30-amp maximum matters when you are protecting higher-draw accessory circuits, while the 12-gauge leads make it better suited to wiring runs that need that conductor size.

On board, it makes sense anywhere a single circuit needs a sealed fuse point without moving to a larger fuse block. That includes small refits, accessory additions, and service work where the original holder has become brittle, loose, or exposed to water over time.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
