Fuse Blocks are an effective method of protection to prevent damage to wiring and possible fire in the event of an over-loaded or short circuit. This Blue Sea Systems space-saving fuse block can provide protection for new installations or when the panel has run out of breakers. Often used for electronic installations, this fuse block can be fed by one breaker from the distribution panel and supply power to 12 additional circuits. Compact size allows it to be installed in tight spaces close to the loads they protect. Accept ATO/ATC fuses that provide protection from 1 amp to 40 amps. Review: Well made, versatile - I used this to safely, cleanly add more circuits to an older vehicle. The split-circuit design was exactly what I needed, because I needed some circuits on battery power, like the radio clock, and some circuits on ignition only, like gauges. It was probably twice as big as I needed, which caused some mounting challenges, but it was helpful to have terminals accessible from both sides. The grounding block also wasn't strictly needed in a car, because you can ground anything to the vehicle body, but it did simply wiring. I found the block to be very sturdy and well-made, and the cover adds another layer of protection. Finally, the built-in fuse puller and spare fuse holder is a good "just in case" feature. Review: Great Split Bus Blade Fuse Block - First off, Blue Sea Systems products seem very well made and I am pleased with the products that I have purchased. I purchased this product for a project I am currently working on. I have a vehicle with a 6V electrical system. I wanted 12V to power other decvices and I wanted to be able to fuse both the 6V and 12V circuits. This product has a split buss that allows for 6 circuits on each of the 2 busses which allowed my to connect two different voltages one on each bus. I used a 6v to 12V boost converter then attached the 12V to one bus and the original 6V to the other. Both busses share common ground connections which I found very convenient. I also like the clear plastic cover so you can see the blade fuses. And with easeyID fuses, with leds that illuminate when a fuse is blown, it is quick and easy to identify which fuse needs replacing. Over all I am totally pleased with the quality and cost of this product. I would, and have already purchased more than one of these devices and would recommend it to others. ## Features - Split Bus Fuse Block with ground for use when a mix of switched and 24-hour circuits are desired in the same block - Provides two isolated groups of six ATO/ATC circuits - For use with either two isolated batteries or with a single battery providing a mix of 24 hour and switched circuits - Screw terminals for securing wires accept ring terminals - Cover satisfies ABYC/USCG requirements for insulation, incorporates an easy to open push button latch providing easy access to fuses, storage for two spare fuses, and label recesses that accept Blue Sea Systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00WM2MWQ4 | | Best Sellers Rank | #1,250 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1 in Fuses #25 in Automotive Fuses | | Brand Name | Blue Sea Systems | | Color | With cover | | Connector Type | Screw | | Current Rating | 100 Amps | | Customer Reviews | 4.8 4.8 out of 5 stars (590) | | Gauge | 11.0 | | Global Trade Identification Number | 00632085050320 | | Included Components | Fuse Block, Cover, 20 write on circuit labels | | Item Dimensions W x H | 3.32"W x 1.51"H | | Item Type Name | boating-electrical-equipment | | Item Weight | 0.29 Kilograms | | Manufacturer | Blue Sea Systems | | Material Type | Plastic, Tin-plated Copper | | Model | 5032-BSS | | Mounting Type | screw mount | | Number Of Contacts | 12 | | Number Of Poles | 12 | | Number of Positions | 12 | | Part Number | 5032-BSS | | UPC | 632085050320 | | Unit Count | 1.0 Count | | Voltage | 32 Volts (DC) | ## Product Details - **Brand:** Blue Sea Systems - **Color:** With cover - **Connector Type:** Screw - **Current Rating:** 100 Amps - **Gauge:** 11.0 - **Material:** Plastic, Tin-plated Copper - **Mounting Type:** screw mount - **Number Of Contacts:** 12 - **Number Of Poles:** 12 - **Voltage:** 32 Volts (DC) ## Images ![ST Blade Fuse Block Dual 12 Circuit with Ground and Cover, 100 Amps, 5032 - Image 1](https://m.media-amazon.com/images/I/71GYI3i7kQL.jpg) ## Available Options This product comes in different **Color, Style** options. ## Questions & Answers **Q: What size Ring terminal do i need and what is largest awg it will accept?** A: The main supply and ground studs are 1/4x 20. I ran 8 ga wire to these with no issue. The individual circuits are #10 for the ground and #8 for the hot. I ran 12-16 ga wire to these, depending on the amount of distance the circuit covered. If you're neat, you could run 12 to each one with no issue. 10 ga might push it al little, but could be done. **Q: Is there a pdf instructions like on the other ones i can download? all i see is a video.** A: I don't know about a pdf, but the back of the package has simple directions on it. Basically on the top of panel you connect your ground and bottom you connect your power. I found this product on a YouTube site called Tiny boat nation. I'm very happy with my result. **Q: Is the first power wire from battery positive and then the Second terminal a trigger wire to enable the other fuses to be turned on?** A: This is a fuse panel intended for marine applications, and they should always be wired directly to the battery. What you are referring to is an automotive type of application, with an "accessory" side, which comes from the battery, via a relay, to a fuse pannel. You can wire this up any way you please, just do it correctly. **Q: Would this be good on a Honda pioneer to run led lights and a winch?** A: Well you could use it for that but both the lights and winch should come with there own relays wiring and switches the winch would. Be the one item I’d tell you not to run to this fuse block just because of the amount of power needed to run it . This is great for adding lights stereo led whip lights 12 volt usb ect. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made, versatile *by A***K on May 9, 2025* I used this to safely, cleanly add more circuits to an older vehicle.
