The insulated nylon base is flame-retardant, Superior Insulation & Strength.
- Wide Application - Bus bar is excellent for managing wires and distributing power, have plenty of connection points for both positive and negative wiring terminals, keep the circuit neat and orderly, make your wires doesn't look like a rat's nest under the hood anymore, reducing the possibility of short circuits. Suitable for cars, trucks, solar, caravans, ships and yachts, etc.
- QUICK FIX: When the current or voltage exceeds the rated limits, the fuse will automatically blow. Each load is equipped with an LED indicator to signal whether a circuit has shorted or if the fuse has blown, allowing for easy identification and replacement. However, it is important to note that there may still be voltage present across the circuit even in the absence of a fuse; this occurs because the fuse box contains its own lighting circuit, which introduces resistance and consequently displays some voltage.
- ENSURE NEAT WIRING: Rather than cluttering your battery terminals with a tangle of wires and fuse holders, the WUPP 12-volt fuse block and ground bus kit provides six dedicated fuses and six grounding points to maintain an organized, clean, and easily accessible wiring system. This simplifies the process of wiring electronics in your vehicle or boat.
- UNIVERSAL PROTECTION: The input rated voltage of the fuse box is 32V,and the input rated current is 100A.Each circuit outputs a maximum current of 30A. All bus bars and fuse pieces are nickel-plated copper, corrosion-resistant and highly conductive.
- SAFE MATERIAL: PBT flame retardant material base,good mechanical strength and high temperature resistance. It is insulated, heat resistant and flame resistant. There will hardly cause any issue like produce fracture, deformation, combustion or short circuit phenomenon.
- FREE BLADE FUSES: 6-Way Package includes: 20A Fuse*4, 15A Fuse*4, 10A Fuse*2, 5A Fuse*2, Labels*2, Screws*4
- Power Busbar Specification: Stud Size: 5/16" (M8) single stud for large terminal connector and wire; Power busbar is able to reach 250A (MAX) when input/output voltage between 12V-48V DC, NOTE: MAX Continuous Current will DECREASE with Temperature & Humidity Effection
- DIY Circuit: Terminal junction box is suitable for customizing battery and wiring setups; It simplify multiple power connections, maintaining a tidy circuit layout and reduce short circuit risks

- Wide Application: M8 single terminal block is designed to hold terminals securely in place; Ideal for various vehicles and vessels, including cars, RVs, yachts, caravans, ATVs, and ship power systems
- Easy to Use: Include a red positive bus bar and a black negative battery junction block; Feature two screws panel for any flat surface install; Allow 360° wire lug installation with no barrier block post; Recessed #10 mounting holes for more aesthetics
- Busbar:Max Voltage:48V DC,Max Continuous Currents:300 Amp;A high-power modular connection structure component with repeatable electrical performance,low impedance,anti-interference, good reliability,space saving,simple and quick assembly
- Material:The base is made of flame retardant nylon glass fiber reinforced,ensures mechanical strength and durability;The distribution block is made of Nickel plated brass sturdy provide excellent conductivity and security in electrical application
- Removable Window:Design of 6 detachable windows,the number of windows can be disassembled according to user needs for unobstructed wiring
- 5/16 inch Studs:The buss bar with 4 x 5/16 inch (M8) studs,which makes the 12-24V terminal block be able to accept 4/0 Gauge wires and terminals:Stainless steel bolts and nuts have the characteristics of corrosion resistance and rust prevention
- Applications:busbar is widely utilized in power systems,industrial control,automation equipment,fire protection equipment,and other fields,providing dependable and efficient power transmission solutions for diverse applications
![True Mods Waterproof Ground Power Distribution Terminal Block Battery Bus Bar [Max. 300V AC/48V DC] [IP65] [Positive/Negative] Insulated Busbar Box for 12V Auto Vehicle Marine Car RV Boat UTV ATV](https://m.media-amazon.com/images/I/41stod1gtTL._SL160_.jpg)
- SOLID PROTECTION - Busbars installed in water prone areas require the kind of protection that most "universal" products just can’t handle. Our fully enclosed, waterproof busbars shield your wiring against water intrusion and accidental shorts.
- BUILT BETTER - You take pride in your project, we take pride in our product. We use copper, not brass, for improved conductivity and corrosion resistance. And the box is heavy-gauge nylon, not cheap plastic, for better heat resistance and longevity.
- A COMPLETE KIT - Our busbar includes all of the seals, terminals and mounting bolts you'll need to get the job done. We even include a 2' 4 AWG power wire; because there’s nothing worse than missing that one small part you need to finish a project!
- BUILD WITHOUT BARRIERS - Your equipment should never hold you back; and these junction blocks don't. With AC/DC Compatibility, carrying a 300V AC & 48V DC rating that supports up to 150A at 32V DC per bus, they are built to make your plans possible.
- VERSATILE - Multiple mounting options simplify the install process. Mount it directly to any flat surface, use the included Z brackets to mount it to uneven surfaces, or even pair it with PWR0312 to create an incredibly powerful distribution center.
