Master Electrician Exam 2025 – 400 Free Practice Questions to Pass the Exam

In a recreational vehicle (RV) campground, the requirement for outlets is based on National Electrical Code (NEC) regulations and the typical setups for RV sites. The NEC stipulates that at least one 20-amp, 125-volt receptacle should be available at each campsite to accommodate the standard electrical needs of recreational vehicles.

The correct choice indicates that 150 campsites are required to have a 20-amp, 125-volt receptacle because this aligns with the standard practice of ensuring adequate power supply for the number of available sites in such campgrounds.

This requirement addresses the need for safe and reliable electrical access for RVs, which typically draw power for lights, appliances, and climate control. The specified parameters ensure that the campground can meet the minimum electrical demands of campers.

In contrast, the other figures do not conform to the NEC standards for the minimum number of receptacles based on the typical size and capacity of RV campgrounds and would result in insufficient electrical service, potentially leading to safety hazards or inconveniences for campers.
