Great Diagnostics for the trailer loads

I have utilized this protector on several trips now with a (30Amp) 32' trailer. It already has come in handy in that I tripped the outside post breaker and had no clue as to why. I checked the surge box and looked at the rolling status codes. (This portable unit has the rolling display). Everything checked out and when I reset the breaker and waited the minute for it's delayed turn-on, I noticed that the trailer was pulling in excess of 30Amps. One of the rolling displays has the amount of amperage being pulled. That is really a nice feature. The culprit was the wife had two space heaters going in the bath while I had the air conditioner running and utilizing the microwave. Our fault, but the surge box let me know about the trailer pulling excess current. This feature of 'amperage draw' should be more prominent in the literature for the buyer because it is great to see if the trailer loads are behaving, not just diagnosing the input power (which it does fantastic too). No issues with the surge box but Amazon does mix up the portable and fixed mounted pictures, so you have to verify with the model number to make sure you are getting which ever unit you want. I have the portable unit, and the main order page is showing the correct picture but the review and checkout shows the mounted picture.

Good product but buyer beware!! Updated 6/5/2018

I really think this is a 5 star product and I was ready to give it 5 stars and explanation follows. Received the product timely and all parts were present. Installation is very easy if you follow the included instructions and photos. The most important part is making sure the terminal block screws are screwed down tightly on the stripped wires. The stripped wire end will typically be multistrand copper wires and after stripping the wire ends, insert into the terminal block and tightly screw down. Wait about 5-10 minutes and re-tighten the screws as the wire strands will deform. I learned this trick from an electrician. After installation and confirming fully functioning unit, I thought I would get on the Progressive Industries website to see if I needed to register my unit to maintain warranty. I read through the warranty and here is the copied statement under voided warranties section: " Installation of hard wired units by any party other than a qualified RV dealer" I then e-mailed them asking about this and their reply was confirmation of voided warranty on self installation. So, if you are a "Qualified RV dealer", you have lifetime warranty but if you are a DIYer or even a qualified licensed electrician who happens to not be a "Qualified RV dealer", then the lifetime warranty is void. Given that, why is this product available for sale on Amazon without a warning? While I do not believe that I will have problems with this item, and I feel competent with my installation and that "qualified RV Dealers" does not necessarily mean competent RV Dealers (I have had my share of work done by "Qualified RV Dealers") I am disappointed by the Warranty restrictions. 6/5/2018: I have been notified by recent purchasers of the EMS-HW30C that PI now will provide Limited Lifetime warranty on this product even with self install!! This is great news and I will revise my review with 5 stars. Proper preparation and installation is still a caveat.

This is a must have item if you are a boat or RV owner!

I have only had this a month for my RV and it has blocked service twice. The reason was less than 100 volts of power. I wonder how often I plugged my boat into questionable power. This is a fantastic product!

22.APR.2016 It is all that it is advertised to be. It works well. The install takes some patience to get the #6 wires cut to the right length and then bent to line up with the lugs. But, that is no fault of the device, it's just the way it is. I put the remote display upstairs in my 5th wheel RV. It's nice to have the information available to me so that I can monitor what electrical devices and appliances I'm using and then make sure I do not trip a circuit breaker or overload the GenSet.

Smart Buy

I just replaced my junction box with it. Protects surges from shore or my 50amp generator without issue. I thought I might have issues with it protecting from the generator due to a couple of reviews on here, but I was more worried about surges from shore stations than my generator. Anyway it works fine with my generator and detailed instructions for use with a generator or external source or both is included. I did not put the wired remote in the interior - I kept it in the bay. Who needs a bright cycling light flashing at all times? Installation was straightforward as far as what to do - doing it was more challenging than I thought. When other reviewers mention the difficulty of working with the wires they are not kidding, so have your RV guys do it if you don't feel like grumbling a bit. I have used it 8+ hours on the generator Onan Marquis Gold 5500 without issue and had it hooked to both a 50amp and 30amp (with adapter) power station. No issues or cut-offs, but if there's any errors it gives you codes to troubleshoot. Last year I had a microwave "pop" and die at a park, so I got this guy because while they're a bit pricey - they're not as bad as these appliances, as you probably know.

Come with excellent instructions and was not difficult at all to install

This is my second Progressive Industries EMS, first was a 30 amp on our travel trailer, when we upgraded to a fifth wheel it has 50 amp service so I had to upgrade. Removed the 30 amp from travel trailer which we traded in and sold it on one of the RV forums right away. By far the leader in the industry for RV power management. I prefer the hard wired version for many reasons, the main one being that it is out of sight, no extra work or connections at campsite and works perfectly. Comes with excellent instructions and was not difficult at all to install. Wouldn't camp without one!

This is the best way to protect your investment.

So I have a bunch of friends who like to go camping RV's. One of my friends suffered an unfortunate incident where he sustained permanent damage to his RV because of a bad wired power supply at a campsite. After speaking with him about his misfortune I knew that I needed to investigate whether a power surge protector even existed for RVs. Luckily, they do. I researched for about a week and found this particular unit. I was impressed with the reviews as well as the design and overall ease of use of this particular product. I went ahead and made the purchase and it arrived very quickly and I was not disappointed with the design and quality of the product. When you take it out of the box, it feels like a quality well-made product. For me though the real test will be when I took it camping which I did later that week. I got to the campsite, got everything set up and then put the surge protector to the test. Passed with flying colors. Very easy to understand gave me accurate readings and gave me the peace of mind I needed to know that my investment in my RV is better protected. In retrospect it has made me feel foolish that I would spend so much money on an RV but not spend a little extra to ensure the safety of all of the things that are inside of it. This particular unit does all of the work for you. When you plug it in it doesn't count down as it analyzes the circuit and if everything checks out it turns itself on allowing power to go to your RV. If there is a problem or a spike, it shuts itself off and protects your RV. This unit is an analyzer and a search protector, meaning that you leave it plugged in the entire time. The unit is well-made and very easy to use and I can't recommend it highly enough. It is for anyone who wants to protect what they've invested their money in.

Great Product all RVers should have.

The first time I used this was at an RV Park. It gave me an error that the unit I plugged into had an issue. The park we were at had just updated their entire park to 50 amp so everything was new. I contacted the park host who came over right away with the onsite electrician. He opened the meter and checked the new wiring and found a the ground wire was completely loose in the connection bar. He reinstalled and tightened the grounding connection and closed the meter unit up. We plugged in the EMS-PT50X again and after running through its checks it signaled the were no more problems and connected the meter to the trailer. Outstanding product I will not plug into any connection unless this in line. Paid for itself first time out of the box. I highly recommend any one that RV’s to use one of these Electrical Management system.

Protector Specification Clarification

Want to point out that on Progressive Industries web site there is a new a comparison chart of all the devices available which should answer any question regarding each protector and what they provide. The chart is very well done.

Progressive Industries Surge Protector

This is a great protector for the electrical system in an RV. I purchased it after purchasing and installing one for a family member. They had it go into protection mode in a Corp of Engineers campground down South. After checking the voltage at the pedestal and finding it to be OK he plugged in the RV. They went shopping and returned to the RV to find the unit in protection mode. Looking at the display showed that the in coming voltage was at 139 VAC. The unit cut power to the RV and protected all the Electronics and AC units from damage that would most likely have happened if operated on that excessive voltage. The clueless manager (as many are) offered a solution of "Maybe when more people plug in the voltage will come down." I talked to another man in a campground this summer who has had 8 times that the unit has cut the power to his RV because of Low voltage, High voltage, or open Neutral. This unit will prevent costly repairs by cutting the power to the RV if problems are found.
