Marine-grade electrical cables: Why can't I just use automotive wire?

A boat's electrical system is subjected to extreme conditions: salt spray, humidity, constant vibration. That's why boat electrical cables must be designed to withstand these stresses. Our cables are manufactured with tinned copper conductors, which offer superior corrosion resistance compared to bare copper. The outer jacket is resistant to weathering and hydrocarbons.

Battery Cables: Gauge and Amperage

Choosing the correct gauge of battery cables is essential to ensure proper electrical system performance and prevent overheating. The gauge must be appropriate for the amperage of the load it needs to supply. In our catalog, you'll find battery cables ranging from 16mm² to 95mm², suitable for batteries of various capacities.

Cable Crimping: The Importance of a Secure Connection

Cable crimping is the technique of connecting electrical cables to terminals (lugs). A properly crimped connection ensures a safe and durable electrical connection, preventing loose connections and current leakage. For a professional-grade crimp, we recommend using a manual or hydraulic cable crimper. Our catalog also includes terminals in various sizes and materials.

What cable gauge should I use to connect the battery to the starter motor?

The cable gauge depends on the cable length and the motor's starting current. In general, for small to medium-sized engines (up to 40 HP), we recommend a cable of at least 25 mm². For more powerful engines, you'll need to use larger gauge cables (35 mm² or 50 mm²).

How do you crimp a terminal correctly?

Use a cable crimper specifically designed for the cable and terminal size. Insert the cable into the terminal and position the terminal in the crimper. Close the crimper until the terminal is securely crimped to the cable. Verify that the connection is solid and strong.

What is the difference between a single-core and a multi-core cable?

A single-core cable consists of only one conductor, while a multi-core cable consists of multiple conductors insulated from each other. Single-core cables are used for wiring simple electrical systems, while multi-core cables are used for wiring complex electrical systems where multiple signals need to be transmitted simultaneously.
