What’s in the box
| Qty | Part | What it does |
|---|---|---|
| 1 | Egis RT fuse block 12-position with ground + LED | 12-circuit blade fuse block with a ground bar and blown-fuse LEDs. Takes ATO/ATC/ATF fuses from 1 to 40A, output wire up to 10 AWG (Egis). |
| 1 | Egis ANL fuse block up to 4/0, 35-750A sealed | ANL fuse holder for the fused feed from the busbar to the fuse block (fits cable up to 4/0). |
| 2 | Victron Busbar 250A 4-point with cover | Busbar, 250A, 4 points, with cover. One for positives, one for negatives. |
| 1 | Pacer Duplex wire 14/2 red/black, 100 ft | Duplex wire, 14 AWG, red and black, 100 ft. For 12V branch circuits like lights, fans and pumps. |
| 1 | Pacer Heat-shrink ring terminal 16-14 AWG 1/4in, 100-pack | Heat-shrink ring terminals for 16-14 AWG wire, 1/4 inch stud, 100 per pack. |
Swaps on this page: Pacer Duplex wire 18/2 red/black, 250 ft. Set the part you don’t need to 0 and the swap to 1.
Not in the box
- The battery
- Main battery cable and its main fuse
- The ANL fuse and the blade fuses, sized to each wire
- Lugs with a 5/16 inch hole for the busbar studs
Who it’s for
Anyone replacing a nest of wires on the battery post with one fused panel, on a boat, van or RV. Works with any 12V battery. It’s steps 3 to 7 of our wiring diagram.
Good fit if: You want to swap the nest of wires on your battery post for one fused 12-circuit panel, on a boat, van or RV.
Not the pick if: You still need a main fuse and battery switch: the small boat lithium upgrade kit adds a class T holder and switch.
How it goes together
You can do this. Here’s how.
- Turn everything off and disconnect the battery, negative first.
- Mount the two busbars and the fuse block where you can reach them. Positive busbar is fed from the battery through your main fuse and switch.
- From the positive busbar, the ANL holder feeds the 12-circuit fuse block. Fuse it for that cable.
- One circuit per blade fuse. Run the small negatives to the fuse block’s ground bar, then one wire from the ground bar to the negative busbar.
- Measure each run out and back, size the wire with the wire gauge calculator, crimp, heat-shrink, and fit a fuse sized to that wire.
- Reconnect the battery (positive first, negative last) and test each circuit one at a time.

Fit rules
- The cable from the busbar to the fuse block gets its own fuse, sized to that cable. The ANL holder is for that. (Guide 2)
- Each circuit gets its own blade fuse, sized to protect that circuit’s wire. (Guide 2)
- The ring terminals are 16-14 AWG with a 1/4 inch stud, to match the 14 AWG wire.
- Size each run for its current and full length, out and back, before you cut. Our wire gauge calculator uses the 3% voltage drop target common on boats.

Questions
Is 14 AWG right for everything?
No. It suits lights, fans, pumps and electronics on shorter runs. Bigger loads and longer runs need bigger wire. Check each one with the wire gauge calculator.
Do I need two busbars?
One gathers positives, one gathers negatives. If you already have one of them, set it to 1 before you add to cart.
Are fuses included?
No. Each fuse is sized to the wire it protects, so you pick them once your runs are measured.
Each part ships from the maker’s distributor, so a kit can arrive in more than one box.
