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. ## Frequently Bought Together - Blue Sea Systems 5026 ST Blade Fuse Block 12 Circuit with Ground and Cover - 6 Gauge Marine Wire,6 AWG 20ft Duplex Marine Grade Wire Tinned Copper Oxygen-Free Insulated Red& Black Electrical Cable for Boat/Automotive/RV/Camper/Trailer - Blue Sea Systems 6006 m-Series Battery Switch ON/OFF with Knob, Red --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/249495008-blue-sea-systems-st-blade-fuse-block](https://www.desertcart.tn/products/249495008-blue-sea-systems-st-blade-fuse-block) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
