Which electrical safety tests are necessary for RVs?

The necessary electrical safety tests for RVs include a combination of several assessments, which is why the choice that mentions 120 vac, hot skin, ac voltage, and GFCI is the correct one.

Conducting a 120 vac test ensures that the electrical system functions safely and within the required voltage parameters. The hot skin test checks for stray voltage on the surface of the RV, which could present a shock hazard to occupants, while the ac voltage test verifies that the alternating current supplied to the RV is stable and conforms to safety standards. GFCI (Ground Fault Circuit Interrupter) tests are essential to ensure that the protective devices are working correctly to prevent electric shock by cutting off power when necessary, especially in wet conditions common to RV use.

This comprehensive suite of tests works together to ensure that the electrical system in the RV is both functional and safe, effectively safeguarding against potential electrical hazards.
