Our fully wired switch panels are meant to terminate onto one of these marine terminal blocks. They are a handy way to break circuits out and troubleshoot electrical issues.
We carry 2, 4, 6, 8, 10, 12, 15, and 20 circuits, or “gang” terminal blocks. Each gang is isolated… so only the adjacent screw is connected.
So your switch panel ring terminals would go on one side, and the load wiring going out to your device would be landed on the other side. This is distinctly different than a Marine bus bar where all the wires are grouped together. We also carry the bus bar which you’ll need for the negative side of the circuit.
Our terminal blocks are rated for 30A per circuit, and 600V. They have Nickel-Plated Brass Contacts. They use a #8 sized ring terminal.
If purchasing to interface your New Wire Marine switch panel, you’ll need:
Example 1:
You have 9 switches. Two are DPDT (the Nav/Anc and the Livewell/Aerator). So you’d need 1 primary input, 2 for the Nav/Anc, and 2 for the Livewell, then 1 more for the other 7 switches. That’s 1 +2 + 2+ 7 = 12 circuits. So you’d need a 12 gang terminal block.
Example 2:
You have 12 switches. One is a Nav/Anc and 4 of them are sending power to 3 night fishing lights each (12 lights total). So you’ll need 1 primary input, 2 for the nav/anc, 12 for the night fishing lights, then 7 for all the other switches. That’s 1 + 2 + 12 + 7 = 22 circuits total. So you’d need at least one 10 post and one 12 post. Or maybe two 12 in-case you forgot something or want to add something later.
Also, you can double up on the same screw. Makes it not quite as clean-looking, but can cut down on the space needed for lots of circuits.
We’ve included a diagram below on how our marine terminal blocks are used in a typical boat’s electrical system.

Have not installed them yet, seem fine
Your website and wiring diagrams are very helpful, what would be more helpful for me would be diagrams showing use of switches/circuit breakers and no fuses. I am not using fuses or fuse blocks.

The do it yourself design process was actually fun. The panel itself is good looking and high quality. Great experience
