5 Fuse Distribution Panel (MEGA + 4× MIDI)
Clean up your battery-side wiring with a compact 1-circuit MEGA + 4-circuit MIDI distribution panel. This holder offers easy, centralized, protection for your inverter and four branch fuses together in one tidy hub — shorter cable runs, easier service, and a safer install right where it matters.
It ships with an included Free 100A MEGA fuse and room for up to 4 MIDI fuse branches — plus a splash-resistant cover to help prevent accidental contact. Built around a tinned copper busbar for lowest resistance and dependable current handling.
This pairs perfectly with marine electronics, solar systems, fridges, diesel heaters and lithium battery systems.

Frequently Asked Questions
What fuses does it take?
The main position uses a MEGA/AMG fuse (a 100A MEGA is included). The four branches use MIDI (AMI) fuses, which you size based on each load and cable.
Does it come with MIDI fuses?
No—MIDI fuses are sold separately so you can choose the correct ratings for your system. Add our UL-Listed AMI/MIDI Fuses (2-Pack) to your cart.
What if my inverter draws more than 100A?
No Problem! Replace the included MEGA fuse with the appropriate size for your inverter, and ensure your feeder cable can support the total load.
Or install a separate heavy-duty fuse for that device, such as an ANL fuse or another MEGA fuse on a dedicated feed.
Can I link multiple holders together?
Yes. Either use the included MEGA bypass busbar, or You can use separate feeds and fusing to link multiple holders for more circuits—popular for larger van, RV, and marine builds.
Can I use it outdoors?
The cover provides splash resistance, but it’s not waterproof. Mount it under cover or in an enclosure to reduce exposure to spray and debris.
Is this a good fit for my van conversion?
Yes. It’s a compact, battery-side hub that keeps wiring short and organized, simplifies add-ons (solar charge controller, DC-DC alternator charger, small inverter), and pairs perfectly with a lithium battery upgrade.
Can I use this in my boat?
Yes—great for marine DC systems. Typical branches include a trolling motor, fish finder, depth sounder, and cabin electronics. Mount in a protected, dry location for longevity.
