Recreational Vehicle (RV) Technician Practice Test

How should the neutral wire be connected to the 120V AC shoreline power in RV wiring?

1. Bonded to ground

2. Isolated and ungrounded

3. Grounded consistently

4. Connected to the battery

The correct answer is: Isolated and ungrounded

In RV electrical systems, proper connection of the neutral wire is crucial for safe operation and compliance with electrical codes. The neutral wire should be isolated and ungrounded in a manner that prevents any potential electrical shock and ensures that the electrical system functions correctly. An isolated neutral wire allows for a balanced load and helps to maintain the integrity of the electrical system by ensuring that any faults do not create a pathway to ground that could produce dangerous scenarios. This is particularly important in a recreational vehicle, where the mobile nature can lead to varying environmental conditions and potential risks. When the neutral wire is properly isolated, it minimizes the chances of introducing ground faults into the system, which could otherwise create hazards not just for the equipment but also for the occupants of the RV. Such an approach facilitates compliance with safety regulations and ensures that the RV's electrical system operates reliably. While bonding the neutral to ground, grounding inconsistently, or connecting to the battery can lead to potential safety hazards and are often not in accordance with electrical code, isolating the neutral keeps the system safe, effective, and compliant.
