What type of connectors should be used for all isolator wiring?

The use of ring or captive spade type connectors for all isolator wiring is crucial due to their reliability and effectiveness in establishing secure electrical connections. Ring connectors are designed to provide a stable and permanent connection to a terminal, which is particularly important in isolator applications where high current flows need to be managed safely. This type of connector ensures that the electrical contact remains secure and minimizes the risk of accidental disconnection, reducing the likelihood of electrical failure or arcing.

Captive spade connectors add an additional layer of safety and convenience. They are designed to stay attached to the terminal, allowing for easier assembly and disassembly, which is beneficial during maintenance or repairs. This feature helps to maintain the integrity of the connection over time, ensuring that it remains operational under varying environmental conditions often encountered in marine applications.

In contrast, flat connectors, barrel connectors, and rotary connectors may not provide the same level of security or reliability for isolator wiring. Flat connectors, while easy to use, can be susceptible to loosening over time. Barrel connectors, typically used for other types of connections, may not be suitable for high-current applications. Rotary connectors are generally used for applications requiring rotation or movement and are not ideal for static connections needed in isolator wiring.
