30 Amp and 50 Amp Portable RV Surge Protector Kits, Modules and Testers

I use this each time i arrive at a RV site to ensure I have clean power. The size 9f the unit is great and I feel good that it is a 2 step process with each device having a purpose.

Easy to use.

have not used but i like this kit

We work camp and in the park were in now it has clean power. I have one 30amp and one 50 amp tester. Sometimes campers come and tell us their surge guard says the polarity is bad and they can't use our power. This is where the Progressive shines best. Plug it in and it shows everything is fine. Which I already know it is and their surge guard is wrong. If they don't trust the proof given from the progressive tester they are left with 2 options. Do not hook up or we can call a certified electrician. If he says it's our fault will pay to fix it and pay him. If however he says there is nothing wrong then that customer has to pay him for his time. No body has taken us up on that offer. LOL. They plug up and everything is fine for their stay.The worst part is you can show them were that sites power was used that very day by a guest who left or the one before that and yet they still don't believe you. They are trusting a surge guard that is just not that good and then you have to prove it to them. These Progressives are very good at testing and Not only do I use then to prove the power is good I use them when we are on the road in our camper as well.

I bought these to protect the transfer switch on my RV. When it fails from voltage problems it is $400 for parts and another $150 for installation. I consider these to be throw-a ways. Cheap by comparison. I bought a second surge guard so I have an immediate replacement should the first one be damaged by excessive voltage issues. I will be up and running again in minutes versus a week or more.

This is well made but comes from China. I carry it as a backup in case my expensive one stops working. I use Progressive Ind, made in USA surge protector for daily use.

Much less expensive than their one piece unit, and the surge protector is not visible once in use.The 30 amp tester unit works like a household tester, plug it in check for green lights, remove it and put it into storage. Put the surge protector on your RV cord, plug it in and your are safely in business.I don't know about longevity, I have only used it once.

This is a really inexpensive item and protects against a power surge for a lot less money than I have spent in the past.

Seems to do what is is supposed to. Love the smaller footprint.

Product is well built , has the handy lights to tell you if you have a good connection or bad connection. Very pleased with the product and I highly recommend it.

Fonctionne comme décrit, à mon deuxième location de terrain de camping la connexion 30 ampère du terrain avait l’air douteux alors j’ai vérifié avec le testeur et le grounds ne fonctionnait pas alors j’ai avisé la personne de la maintenance du problème,qui va le réparer.

Je l'ai acheté suite à une recommandation de mon association de camping et de caravaning. Je l'utilise depuis quelques semaines et je n'ai éprouvé aucun problème à date. Le futur nous en dira plus.

Had a small trailer with no air conditioner so did not need a big surge protector. This was a perfect for my application.
