The maximum battery cable gauge that can be connected to a terminal via wingnut is indeed 8. This is based on standards stipulated by organizations such as the American Boat and Yacht Council (ABYC), which outline the methods for secure and effective electrical connections.

Using an 8-gauge wire ensures adequate current-carrying capacity and minimizes voltage drop over longer runs. Additionally, it allows for proper torque on the wingnut connection, which is essential for maintaining a secure and reliable electrical connection. If the cable gauge were too small (such as 10, 12, or others), it could lead to higher resistance, increased heat generation, and the potential for connection failure or reduced performance of the electrical system.

Choosing the correct gauge is particularly crucial in marine applications where environmental conditions and system reliability are paramount. Thus, adhering to the recommended usage of an 8-gauge cable when connecting to terminals via wingnut contributes significantly to the safety and efficiency of the electrical system.
