Sea-Dog 426671 vs 426710 Marine Busbars: Terminal & Size Guide

The first is a 10-terminal non-fused busbar; the second has five branch screws plus two main studs, with a manufacturer-listed maximum of 100A at 48V DC.

| MPN | Connection layout | Construction | Published rating | Manufacturer A × B |
|---|---|---|---|---|
| 426671-1 | 10 shared-bus terminals | Stamped brass / molded Bakelite | Not specified on this model's manufacturer chart | 5¾ × 1¼ in |
| 426710-1 | 5 × #8-32 plus 2 × #10-24 main studs | Tin-plated brass / ABS | 100A maximum; 48V DC maximum | 4 3/16 × ⅞ in |
A busbar is not a fuse block. Both products join electrical connections without supplying overcurrent protection. Sea-Dog's 426710-1 includes five #8-32 branch terminals and two #10-24 main studs. The manufacturer's page confirms a 100A/48V DC maximum for this model; it does not publish an equivalent current rating for 426671-1 in the compared chart, so that rating is not assumed.
Manufacturer dimensions, in order A/B/C/D: 426671-1 is 5¾ / 1¼ / 1 1/16 / 5 3/16 inches; 426710-1 is 4 3/16 / ⅞ / 1⅜ / 3 7/16 inches. The letter labels refer to Sea-Dog's original drawing, not automatically the opening size. The 426671-1 calls for two #10 flat-head screws; the 426710-1 calls for two #10 round-head screws. Fasteners are not included.

How to check the correct replacement
- Decide whether the installation requires a 10-terminal shared bus or a five-branch block with two main studs.
- Use the manufacturer's A–D drawing to compare length, width, height and mounting screw spacing.
- Use correctly terminated marine-grade wire and match each screw or stud to its intended lug.
- Keep positive and negative distribution separate unless the system is specifically designed otherwise, and install appropriate overcurrent protection.
- Do not apply the 426710-1's 100A/48V DC rating to 426671-1 without a verified rating for that part.
