You could connect your wires the way it suits you most. With that being said, some people will put the "input" wires on the bottom and the "output" ones on the top. At least, that's what I did. **Q: is there something wrong with putting 2 positive wires onto the product to use as shut off..while still having fuses in line?** A: No **Q: I would like a diagram of exactly how to wire this up. also, i see the seller mentioned a manual. can i request one also?** A: This breaker is as simple as it gets. As you look at the breaker there is a plus and minus indicators at the very top of the breaker. This is where your 12 volt supply connects. The 2 bottom terminals correspond directly to the 2 top terminals, positive on the right, negative on the left, top to bottom. These terminals on the bottom are what you connect the load you are protecting to, for example a solar charge controller or a solar array. The wiring schematic is located on the front of the breaker. I can't answer to the manual, I did not need one. You can go to You Tube and view a number of tutorials on these breakers. **Q: Are the terminals large enough to take a 1/0 awg cable?** A: The terminals are small for 1/0 but good for smaller wires from PV. ## Frequently Bought Together - CHTAIXI DC Miniature Circuit Breaker, 2 Pole 1000V 20 Amp Isolator for Solar PV System, Thermal Magnetic Trip, DIN Rail Mount, Chtaixi DC Disconnect Switch C20 - TKDMR 10pcs 1/0 AWG-3/8 Battery Lugs,Heavy Duty Wire Lugs,Ring Terminals,Battery Cable Ends,0 Guage terminals,Battery Terminal Connectors with 10pcs 3:1 Heat Shrink Tubing - Nilight Battery Disconnect Switch 100A Master Disconnect Isolator 12V-48V On Off Power Cutoff Switch Waterproof Heavy Duty for Marine Boat Car RV ATV UTV Yacht, 2 Years Warranty --- ## 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.sn/products/348183578-dc-miniature-circuit-breaker-2-pole-1000v-20-amp](https://www.desertcart.sn/products/348183578-dc-miniature-circuit-breaker-2-pole-1000v-20-amp) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-28*
