What type of strain relief must be provided for wiring passing through the galvanic isolator case?

The appropriate type of strain relief required for wiring passing through the galvanic isolator case is passing strain relief. This type ensures that the wiring is secured and protected from mechanical stress, which could compromise the integrity of the connections or lead to potential failure. Passing strain relief specifically accommodates the movement and flexing of the wires as they enter or exit the isolator, maintaining a robust and reliable connection without undue strain on the conductors.

Choosing passing strain relief is essential in marine applications, where vibrations and physical motion are common due to the environment. Proper strain relief not only safeguards the wiring from wear and tear but also minimizes the risk of electrical faults, which could be hazardous.

Other options, while they might provide some level of support or protection, do not specifically address the needs of wiring transitioning through an isolator case. Support brackets could hold wiring in fixed locations but are inadequate for accommodating dynamic movement. Strain relief clamps might serve to secure wires but may not provide the necessary flexibility and freedom of motion in a galvanic isolator situation. Heat shrink tubing could protect individual wires but does not offer the comprehensive support that passing strain relief does.
