Made in the USA and only on hour from my house...who knew? I knew there was a company there that made electrical components but no idea they made these. I found them searching after my Surge Guard brand started acting up and wouldn't let power through it after 4 years. Of course it only had a 1 year warranty. I wish I knew about Progressive Industries since they have a lifetime warranty and made in the good old USA in North Carolina. They say its not covered in the event of floods, hurricanes, earthquakes, lava flows, sharknadoes and zombies. Also not covered if you drove off leaving it hooked to the pedestal, auto wrecks etc.. So seems like as long there is no wrath on you and you aren't an idiot you have a surge protector for life. I took some pictures comparing it to the old one and the LED's are much brighter than the old one when it was new. Seems made very well and even has a 7 day a week number to call for tech help. Sold me!

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.

I purchased this item, the 50 amp one and then took it out on a few trips after I got it. To be fair I had it a few weeks before I left which ate into my return window. At first, I thought the two error codes I was getting at our first RV Park was because it was working, but then we stopped at two more places on our trip and I kept getting the same two warning codes. Okay that can't be good and I wanted to ask about an exchange, perhaps I got a dud... it happens, but I am not outside my "return window". I will contact the seller since they state they have a lifetime warranty and see if they will do that because this really is an item that every RVer should have. I'll update later, but in the meantime, I don't what to buy another if they'll help and they're not cheap. At the same time I'll need one for my upcoming, and long trip.

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.

The hardest part of installing the HW30C is deciding where to put it. The rest of the installation is straightforward, with plenty of text and pictures. Tech support phone numbers are shown in the instructions, and I called before removing the time delay jumper to be sure I was removing the correct part. The phone was answered almost immediately, and the assistant was very helpful. Based on other comments I see here of folks returning the product due to missing parts, I'd recommend reading ALL of the instructions before starting the install. Only 2 screws are used to hold the cover in place during shipment. The rest, along with all other parts, are contained inside the unit in plastic bags and bubble wrap. One caveat - I say the installation is easy, but what's easy for some is impossible for others. I'f you're capable of installing lighting and switch fixtures in your house, you'll have no trouble. Otherwise, consider having someone else install this product.

I chose to remove my trailer's wire junction box near the external plug-in point and replace it with the surge protector. The large round cord that feeds the trailer's circuits contains flexible, stranded wires, and installation was easy following instructions and pictures. The inductive amp pickup goes over the black wire with the arrow side facing the contactor. The short cord that runs from the trailer's power-in receptacle to the junction box may be (mine was) identical to what's in your house walls; 12-3 solid copper that's very stiff and hard to manipulate. Use a needle nosed pliers to bend a loop into the end of the ground wire, and secure that loop directly to the ground buss bar using a provided screw and nut. The black and white solid wires will give far less trouble if you use your pliers to bend the wires into a zig-zag pattern as necessary, similar to a wiring diagram, so that the bare ends slip easily into the slots of the contactor. Install the lid, connect the remote wire to the phone jack, and secure the unit in the location you chose using four screws (not provided). You'll need to massage the cord with solid wires as you place the unit to avoid undue strain on the unit's plastic chassis.

I chose to place the remote display in the same area where the unit is installed, so I can monitor the hookup as soon as I plug in and disconnect if there's an issue. If a person wanted to monitor the volts, amps, etc. continuously, a second remote can be installed inside the coach. This shouldn't be necessary, as the product will shut down power if a bad situation develops, and you can then go outside and check the error code on the display.

Regarding the time delay jumper, the instructions state to remove it to provide a 136 second delay between pedestal connection and power to the coach if your AC unit doesn't have a built-in time delay. Mine doesn't, so I pulled the jumper. Upon plugging in at the pedestal, the display scrolled properly and showed zero amps being used, and a voltmeter inside the coach showed zero voltage. 136 seconds later, I heard the contactor snap closed, and all AC items in the coach were powered. Whether you install this yourself or pay someone to do it, it's a worthwhile investment that'll pay for itself ten times over the first time you plug into a 115V pedestal that's been wired for 240V.
