True or False: Pre-wired battery chargers with isolated outputs require overcurrent protection on both positive and negative outputs.

The assertion is true because pre-wired battery chargers with isolated outputs indeed require overcurrent protection on both the positive and negative outputs. This requirement is rooted in safety and compliance with electrical standards.

Overcurrent protection devices, such as fuses or circuit breakers, are essential to prevent excessive current flow that can lead to overheating, damage to the charger, or even potential fire hazards. In a system with isolated outputs, if overcurrent protection exists only on one side (either positive or negative), there remains a risk that a fault on the unprotected side could result in a dangerous situation.

By installing overcurrent protection on both outputs, the entire circuit is safeguarded, ensuring that if either output experiences a fault condition, the protection device will interrupt the current flow, thus minimizing the risk of damage and enhancing overall system reliability and safety. Properly following this practice is aligned with standard safety protocols in electrical systems, especially in marine and similar applications governed by the ABYC standards.
