Surge protection necessary?

Is surge protection necessary for shore power hookup? If so what recommendations?

Depends. My trailer has practically no modern, voltage sensitive, electronics. Your unit may have all kinds of delicate control boards, inverters, converters... That would be genuinely unhappy with either too high or too low an AC voltage.

"Power Surges" are extremely rare. You are far more likely to encounter low voltages or incorrectly wired power pedestals (hot on the neutral, no neutral, poor ground).

For what it is worth, in 10 years, 65000 miles, I have encountered exactly zero electrical problems.

No surge problems but I have seen low voltage at different campgrounds, primarily because their underground cables are too small for the loads people are putting on them these days I think. Big camping rigs, lots of electrical equipment running. Low voltage can damage some equipment.

So we use a surge guard at the power pedestal that protects against a variety of power faults, it also runs a number of power checks before it allows pedestal power to the Airstream when hooking up.

I was just at a thousand trails RV park near San Diego that had an open ground. My power protection device saved my electronics and possibly my electrocution when contacting the outer skin while standing on the ground.
I never hook up without protection!

Surge protection necessary?

Surge protection devices are cheap insurance against potentially catastrophic electrical system overloads.

I have been involved in 'more than several' situations where floating neutrals, 240 VAC running along a 120 VAC line or over/under voltage events have caused significant damage to electrical systems, batteries, appliances and similar electrical devices........ some over $10,000 in damage.

If you frequently camp in RV parks, you owe it to yourself to be properly protected!!

We chose to use the Hughes Autoformer after talking with many other RV'ers.

TRC SurgerGuard or the Progressive Industries units.

Surge protectors are one of those things that you don't need until you need it and if you don't have it then it is to late to get it. When you think about it the piece of mind that it gives you IMO is well worth the the price of it. I use mind at home and at every campsite that provides electric.

had on wired in the trailer when I bought it now everything is protected. keep in mind some older campgrounds are a wiring mismatch at best

Agree completely. All you need is for one surge to fry or damage your electronics for the surge guard to have paid for itself. RV parks are not known for consistent electricity. I have a Hughs Autoformer and love it. No longer worry about what Iím plugging into.

I installed one of these. It was a fairly simple install. It has protected my stuff from low voltage, open neutral, and open ground conditions.
