Galvanic isolators with pigtail conductors must meet the strain relief test for which type of conductors?

Galvanic isolators are critical components used in marine electrical systems to prevent galvanic corrosion, which can occur when different metals are immersed in an electrolyte, such as seawater. The mention of "pigtail conductors" refers to short conductors that are typically used to connect the isolator to the electrical system.

AC grounding conductors are designed to create a safe path for electrical current to flow back to the ground in case of a fault, preventing electric shock hazards and ensuring the proper functioning of a circuit. The requirement for these conductors to meet the strain relief test is essential because it ensures that the connections remain intact under mechanical stress and movement, which is particularly relevant in marine environments where vibrations and movement are common due to waves and wind.

By passing the strain relief test, AC grounding conductors are confirmed to be resistant to disconnection or damage, thus maintaining safety and reliability in the electrical system. Proper strain relief helps ensure that the galvanic isolator continues to function effectively, providing protection against corrosion and maintaining the integrity of the electrical system overall. The other types of conductors mentioned do not have the same level of relevance when considering the specific safety protocols associated with AC grounding in marine applications.
