Recreational Vehicle (RV) Technician Practice Test

Which receptacles in an RV must be GFCI protected?

1. Only the kitchen

2. Only the exterior

3. All exterior, kitchen, and bath receptacles

4. Only the bathroom

The correct answer is: All exterior, kitchen, and bath receptacles

GFCI (Ground Fault Circuit Interrupter) protection is essential in areas where there is a higher risk of electrical shock due to moisture or water exposure. In an RV setting, GFCI protection is required for all exterior receptacles, kitchen receptacles, and bathroom receptacles. The reasoning behind this is that kitchens and bathrooms are commonly used for cooking and personal hygiene, respectively, where water is prevalent. Exposed to water, electrical equipment presents a significant danger of short circuits or electric shocks. Furthermore, exterior receptacles are equally at risk, as they could be exposed to rain or snow. Ensuring that all these areas are GFCI protected enhances safety by cutting off the electrical supply in the event of a ground fault, thus preventing potential accidents and injuries. This comprehensive approach to GFCI protection aligns with safety codes and standards, making it the correct answer.
