Blue Sea Systems ST Blade Fuse Block: Centralised Power Distribution for Marine and RV Systems

Streamline Your 12V and 24V Electrical Systems

The Blue Sea Systems ST Blade Fuse Block (12 Circuits) is the industry standard for consolidating branch circuits in demanding mobile environments. Designed to eliminate the "rats' nest" of in-line fuses and messy wiring often found in boats, caravans, and 4WD canopies, this distribution block offers a professional, safe, and reliable solution for managing your DC electrical connections.

Engineered for 12V and 24V systems (rated up to 32V DC), this unit allows you to power up to 12 separate accessories—such as fridges, lighting, water pumps, and navigation electronics—from a single reliable source. With a maximum total amperage of 100A per block and 30A per circuit, it is robust enough to handle the power requirements of modern off-grid setups while ensuring specific circuits are protected against overcurrent faults.

Integrated Negative Bus for Simplified Wiring

One of the standout features of this model is the integrated negative bus. In many electrical installations, finding a clean and accessible location for return lines (grounding) can be a challenge, often leading to stacked terminals on battery posts. This fuse block includes a built-in negative bus with #10-32 (Approx. M5) stud terminals, allowing you to run both positive and negative wires to the same block.

This design not only saves significant installation time but also reduces the number of connections required, minimising voltage drop and potential failure points. It creates a compact, self-contained power hub that makes troubleshooting easier in the future.

Marine-Grade Durability and ABYC Compliance

Built to withstand harsh saltwater and outdoor environments, the unit features tin-plated copper buses and fuse clips. This plating provides superior corrosion resistance compared to bare copper, ensuring consistent conductivity over the life of the vessel or vehicle. The base is constructed from reinforced polycarbonate, offering excellent heat resistance and strength.

The included insulating cover is designed to satisfy ABYC and USCG requirements for electrical insulation, protecting the fuses from accidental short circuits. The cover features an easy-to-open push-button latch, storage space for two spare fuses, and label recesses that accept Blue Sea Systems' Small Format Labels (sold separately), ensuring your system is clearly identified and compliant.

Key Features

  • 12 Independent Circuits: consolidate varying loads into one central hub
  • Integrated Negative Bus: simplifies wiring by providing a central ground point
  • High Current Rating: Supports 100A total continuous current and 30A per circuit
  • Corrosion Resistant: Tin-plated copper components for marine longevity
  • Safety Cover Included: Meets insulation requirements and stores spare fuses
  • Wide Voltage Range: Suitable for 12V and 24V DC systems (Max 32V DC)

Installation and Technical Context

This fuse block is designed for versatility. It accepts standard ATO® and ATC® fast-acting blade fuses, which are widely available and easy to replace. The main positive distribution bus utilises a #10-32 (Approx. M5) stud, while the branch circuits use #8-32 (Approx. M4) screws with captive star lock washers to ensure secure connections even under vibration.

*Note: While rated for 100A maximum, typical de-rating factors apply based on ambient temperature and wire sizing. Ensure your supply cable is fused appropriately at the battery source.

Whether you are refitting a yacht or building a custom 12V system for a camper trailer, the Blue Sea Systems 5026 fuse block delivers the reliability and organization required for professional-grade electrical installations.

Secure Your Electrical System

Fast paced romantasy you will not want to put down!
Format: Kindle
4.25 stars! I LOVED this book with similar vibes to Hush Hush, Fourth Wing, and The Serpent and the Wings of Night! It was fast paced with easy world building and will keep you turning the pages late into the night because you will not want to put it down! Huntyr is a fierce bad@ss FMC trained to kill vampyres her entire life. She is sent on a mission to go to the academy and earn her spot into The Golden City. Upon arrival, she is forced to room with the delicious fallen angel, Wolf, who is the only one who knows about her assassin identity. The romance, the plot twists, the secrets revealed, the battles, and the tantalizing training scenes had me hooked! And that ending…. I’m holding my breath in need to know hell! Read if you love: 🪽 Fae, Vampyres, Fallen Angels 🪽 Academy setting with magical trials 🪽 Forced proximity and slow burn 🪽 Rivals to lovers 🪽 Hidden identities and secrets 🪽 Tend your wounds “𝘖𝘧 𝘤𝘰𝘶𝘳𝘴𝘦 𝘐 𝘸𝘢𝘴 𝘸𝘢𝘵𝘤𝘩𝘪𝘯𝘨 𝘺𝘰𝘶.

Excellent Rivals to Lovers!!
Format: Kindle
The tension and banter between Huntyr and Wold was delectable. I absolutely love the fallen angel and all of his flaws. Huntyr is amazing too being a badass FMC with some major trauma. The world building was great and I enjoyed the training aspect of the story. The writing was immersive and was in the story the whole time. The ending had quite a twist that I hadn’t anticipated and made my jaw DROP. Excellent job! I also loved the narration. Laura is one of my fave narrators!

Fallen Angels, fae, vampires, oh my!
Format: Kindle
Rating: 4.5 | Spice: 2 (but a good slow-burn) • Main Characters: Huntyr and Wolf • I couldn’t wait to read this book; there was so much hype about it! And there was no doubt why. I fell in love with the characters and the plot itself. This book is mainly plot driven more than friction driven but it’s easy to follow along with. The characters are fun, easily understood. The main setting is at an academy where both the main characters are going through trials and building strength for the final test, The Transcendent. There are fantastic side characters as well. I loved the camaraderie between Huntyr and her friends. But we don’t like Lanson. 😆 We do have some plot twists that come into play throughout the book. Secrets and betrayal to be seen. I did adore Wolf and Huntyr’s relationship. It was a classic slow burn trope. They didn’t hit it off fast, but in time their feelings grew. I loved their banter, so sexy. Wolf is your next book boyfriend; Huntyr is your next vampire assassin independent bad-a*s female. Themes include loyalty, trust, self-discovery, a true slow burn romance. Side note: book ends on a angsty cliffhanger! • Emily, thank you for writing this awesome novel and I cannot wait to devour Book 2, Blood So Brutal! 😍 • Happy reading, my lovelies! xo

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!
