Best Boat Wire Terminals Buying Guide
Before choosing the best boat wire terminals you should consider following options:
1. Number of Terminals Required: The first thing to consider when buying a set of boat wire terminals is how many you need.
If your boat uses a single battery, you’ll only need a single set of terminals. If your boat uses dual batteries, you’ll need a pair.
You should also consider the number of circuits you’ll need and the types of connections you’ll need to make: battery to engine, engine to alternator, and alternator to battery.
2. Cable Size: The next thing to consider is the size of the wire you’ll be using. It’s important that the wire fits through the eye of the terminal.
This can sometimes be a tricky thing to figure out. Fortunately, most manufacturers will provide you with the maximum wire size that can be used with their terminals.
3. Contact Size: Terminals are made with either solid or split contacts. Solid contacts are generally used for low current applications like battery charging.
Split contacts are used for high current applications like trolling motors. The size of the contact is important because it will determine the amount of current the terminal can handle.
4. Amp Rating: The amp rating of the terminal is determined by the wire size and the contact size.
If you’re using the terminal for less than the maximum amount of current that the eye can handle, you’ll want to make sure it has a higher amp rating than what you’re planning on using.
This allows for a margin of error in case the wire gets damaged and reduces the amount of heat that the terminal will generate.
