Review: 👍 - 👍 Review: A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One The Blue Sea Systems 5026 ST Blade Fuse Block is a flat-out outstanding product that earns every bit of 5 stars, and having installed several versions of it across different projects I can say with complete confidence that it is the fuse block to use. The 12-circuit layout with integrated ground and cover is thoughtfully engineered and makes for a clean, professional installation every time. The 100-amp capacity handles demanding electrical loads without any concerns, and the individual circuit fusing keeps everything properly protected and organized. The build quality is exactly what you expect from Blue Sea Systems—solid, marine-grade construction that holds up to vibration, heat, and the demands of vehicle, RV, boat, and off-grid solar applications equally well. The transparent cover protects the fuse connections from moisture and debris while still allowing a quick visual inspection of all circuits without removing anything. Labeling circuits is straightforward, wiring is clean and accessible, and the overall installation experience is as professional and reliable as the end result looks. For anyone building out a 12V electrical system on an RV, boat, truck, or solar setup, this is the fuse block I recommend without hesitation every single time. If you want to do your electrical system right, start here. Highest possible recommendation. ## Features - St blade fuse block - 12 circuit's with negative bus and cover - Positive distribution bus with #10-32 stud - Can be used for 24-hour circuit's - 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 - Accepts ato and atc fast acting blade fuses ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001P6FTHC | | Best Sellers Rank | #5,963 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #14 in Fuses & Holders | | Brand Name | Blue Sea Systems | | Color | Beige | | Connector Type | Screw | | Current Rating | 100 Amps | | Customer Reviews | 4.8 4.8 out of 5 stars (6,545) | | Global Trade Identification Number | 00632085050269 | | Included Components | FUSE BLOCK ST BLADE 12 W/GRD/CVR | | Item Dimensions W x H | 8.4W x 16.4H centimeters | | Item Type Name | FUSE BLOCK ST BLADE 12 W/GRD/CVR | | Item Weight | 0.1 Kilograms | | Manufacturer | Blue Sea Systems | | Material Type | Tinned Copper | | Model | 5026 | | Mounting Type | screw mount | | Number Of Contacts | 12 | | Number Of Poles | 12 | | Number of Positions | 12 | | Part Number | 5026-BSS | | Specification Met | ISO 8846, SAE J1171 | | Temperature Range | 5E+1 Degrees Celsius | | UPC | 632085050269 | | Unit Count | 1 Count | | Upper Temperature Rating | 122 Degrees Fahrenheit | | Voltage | 32 Volts (DC) | ## Product Details - **Connector type:** Screw - **Current rating:** 100 Amps - **Material:** Tinned Copper - **Mounting type:** screw mount - **Number of contacts:** 12 ## Images ![ST Blade Fuse Block - Image 1](https://m.media-amazon.com/images/I/71vlKyD5mWL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: What size ring connector is needed to attach wire to terminals?** A: They are #8 as described in the description. Hard to find #8 rings in heat shrink connectors. #10 worked just fine for the terms and it seems all manufacturers sell this size. **Q: Can I run +/- from batt to 100 amp breaker then +/- to fuse box so I can kill power to fuse box?** A: Yes you can. The fuse box will be powered off breaker. I used a toggle switch panel instead of a main breaker. **Q: Product page says this can handle 100 amps per block, does that mean 100 amps on the left 6, and another 100 on the right?** A: No, it means 100a peak draw for the entire block...30a peak per circuit. The main positive in should be fused at 125 per the specs from BlueSea. **Q: Does this block come with a positive and a negative bus? I don't want to have to daisy chain the positive lead to each lead on the panel...** A: Yes, it does indeed come with both a positive (fused) bus and a negative bus. Very nice unit, as with all Blue Sea products. I would and have bought again after purchasing mine. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 👍 *by K***D on 22 December 2023* 👍 ### ⭐⭐⭐⭐⭐ Review *by J***N on 13 April 2026* A Go-To Fuse Block – I've Installed Several and Will Keep Coming Back to This One The Blue Sea Systems 5026 ST Blade Fuse Block is a flat-out outstanding product that earns every bit of 5 stars, and having installed several versions of it across different projects I can say with complete confidence that it is the fuse block to use.
