30 amp portable RV surge protection

I have read several threads on this great forum about surge protection and finally purchased a Progressive Ind. EMS-PT30C. Based on features and lifetime warranty this is probably the best you can buy, but also the most expensive. Best price on line was at RV upgrades.com ... $220 plus $15 shipping. Arrived yesterday' and the trailer is in my shed with a dedicated 30 amp outlet. Plugged in the protector and received an error code. i.e. reverse polarity condition (hot and neutral wires reversed). During storage I have had a trailer plugged in w/o protection for 7 years and no apparent problem. Does anyone know if or why reverse polarity s/b an issue? I opened the wall receptical and switched the wires ... problem solved. I believe this is the only 30 amp unit on the market that has reverse polarity alert????? HOWEVER, my next problem was not as easy to fix. I could not insert the male plug on my power cord into the outlet on the surge protector. I did everything except use a hammer to force it in. Round pin hole clamps would not move apart. Lifetime warranty with phone number was included with directions. Called Progressive Industries and talked to company President, Tom Fanelli. This problem should not exist, so he is sending me a new unit today along with a pre-paid shipping label to send the defective one back. I like this kind of customer service!

Curious, did anyone else have any problems with surge protectors?

Read following article which describes what can happen with reverse polarity. I have the hard wired unit so no issues for me.

Here is a link to the dangers of Reverse Polarity.

Reversed Polarity Outlets | Structure Tech Home Inspections

Sounds like good customer service from Progressive Industries. My next camper will have one of their units.

Surge protection is something I do not have yet, but I know I need one and I will be investigating it this year. The Progressive Industries units are already at the top of my list and this post confirms that.

Thanks Fonzie! That really answered my questions. I now realize I was fortunate these past years in that I never used any of the appliances while parked in the shed and plugged in to the reverse polarity outlet.

I received the replacement surge protector from Progressive Ind last Sat along with the pre-paid return label. Warranty service doesn't get any better than this!

If you are looking for a surge "protector" stay away from Progressive Industries "Smart Surge", they are a surge status "indicator" and polarity tester which means they only tell you if a surge occurred or there is a reverse polarity issue. Make sure you purchase a surge protector that states that in the description like Technology Research surge guard with ground.

From Amazon.com

Technology Research:
TRC Surge Guard With Shock Shield
Perfect for Pop-ups and Travel Trailers
Automatically shuts off the power when ground faults are present
Requires manual reset after a ground fault
Provides shock protection

Progressive Industries:
1 yr. mfg. warranty
Surge Status Indicator
Polarity tester
Compact Size

Reversed polarity will not damage anything because it alternating current. But it is wise what you did. It just safer and some new electronics do not like it. I had the same problem when mine was new added some dietel contactor grease I think it's called and after a couple of hook-up it went away.

You may want to check that statement out further. Just a suggestion.

To be clear, the recommendation from the groups here is for the progressive industries EMS power protection units. which are superior to the others on the market IMO, of course, except for the transformer units (Franks) that also help boost the voltage when to drops to low.
