Campground electrical pedestals aren’t all created equal, and the differences often become apparent only after you’ve plugged in and started using appliances. Older campgrounds frequently retrofit existing electrical infrastructure rather than installing completely new systems, which means the 50-amp service at site 15 might be fed by different wiring than the identical-looking pedestal at site 20.
The most common issue involves voltage drop during peak usage times. Campgrounds typically wire multiple sites to share electrical feeds, so when your neighbors fire up their air conditioners simultaneously, the available voltage at your pedestal can drop significantly. RVs are designed to operate efficiently at 120 volts, but many campgrounds deliver anywhere from 105 to 125 volts depending on load and wiring quality. This variation explains why your air conditioner runs fine at some parks but struggles at others with seemingly identical hookups.
Distance from the main electrical panel also matters more than most campers realize. Sites located far from the campground’s main electrical service often experience more voltage fluctuation, especially in older parks where wire gauge wasn’t sized for the distances involved. This is why experienced RVers often request sites closer to campground facilities — it’s not just about convenience, but also about more stable power delivery.
A simple multimeter that checks voltage at your RV’s inlet can help identify problematic sites before you damage appliances. If you consistently read below 110 volts or above 125 volts, it’s worth requesting a different site or using surge protection equipment designed for the voltage variations common in campground settings.
