Never plug into a pedestal without a surge protector
Campground power is not the clean 120 volts your appliances expect. Miswired pedestals, brownouts when the park fills up, and lightning-season spikes have killed more air conditioners and converters than any other single cause. A surge protector with an electrical management system (EMS) is the cheapest insurance you can buy.
What an EMS actually catches
- Low and high voltage A loaded park can sag below 105 volts, which cooks A/C compressors. An open neutral can push 240 volts onto a 120-volt circuit. An EMS cuts power before either reaches your rig.
- Wiring faults Reverse polarity, open ground, and miswired pedestals are common, especially in older parks. A plain surge strip ignores all of these. An EMS reads the pedestal and refuses to pass bad power through.
Use it right
- Plug the EMS in first Connect it to the pedestal before your shore cord, let it analyze the power, and read the fault code if it throws one. Expect a deliberate delay of up to a couple of minutes before it energizes. That pause protects the A/C compressor.
- Portable or hardwired A portable unit moves between rigs and lets you test the pedestal before you commit. A hardwired unit lives inside the trailer, cannot be stolen off the post, and protects on every connect and disconnect. Either one beats nothing.
