Is there any difference between
Progressive Industries HW50C and
Progressive Industries EMS-HW50C
on Amazon.
The first date available on the EMS-HW50C on Amazon is more than a year later.
Both pictures show EMS-HW50C on the picture of the device.
They are both on Amazon $30 difference in price. Less for the EMS-HW50C.
I don't see any difference at Progressive Ind website.
A bit confusing.

Amazon can be funny like that. I do believe they are the same unit. Progressive now seems to have a third unit, besides the EMS PT50C and the EMS HW50C. The EMS LCHW50 wasn't around before. Looks at first glance to be a new Hard Wired version with the sacrifice of the remote display...at a decent savings. I have the EMS PT50C because I like the portability.
Yup. According to the website, there are only the 3 choices: Portable, Hard-wired and hard-wired with remote. EMS-HW50C (http://www.progressiveindustries.net/ems_hw50c.htm)
I use the hand held unit 50 amps. Plug it in first to ck voltage and see if the ground is right and the legs are installed correctly. Then plug in the coach. Control low and high voltage going to coach. Blinks code is anything is wrong. Had since 2008. Progressive has great warranty. Any issues just call them and they replace or repair at no cost. DAN
Ditto on what Dan just said. The portable unit seems to work pretty well. But I have had times when the shore power tested fine, but then when I hooked up the coach, I had problems (i.e., when the current started to run). Once it was due to a faulty circuit breaker and twice to a defect in the female plug. But it has always prevented problems in the coach when I did have a defect in the shore power and that is what it should do.
I put in the hardwired model. I got 4 ft of the fine stranded wire of the appropriate size at Home Depot. Took about two hours to put in. I have to move the display to a better place. I want it inside.

I ordered the hardwire without remote. $314- to my door. good investment
I'm very happy with their basic SSP-50 Smart Surge Protector. Works well for me, and you can't beat the protection - both surge and lifetime warranty!!!
Obviously the EMS's job is to protect coach from over & under voltage. But we look at the inside display all the time when on 30-amp and when campground voltage is questionable. EMS is our only shore/generator amp and volt readout for each 50-amp line. Don't know how we could get along without our inside Progressive Industries inside readout, which we mounted in the kitchen next to our 12-volt meters. So for us EMS has two functions: over/under protection AND to give us a meter on the AC world.
This just happened today: On this cold day, we are camping at an Elks Lodge that has six 30-amp RV sites, and I saw a note on the kitchen counter "hot water OFF", so I asked Cindy why she wrote it. Cindy said she turned on a space heater and saw that the EMS readout jumped up 7-amps, and since we were going to run two heaters and microwave, she though our total amps may trip the campground breaker. I looked at heaters and saw that Cindy taped a note on each that said '7-amps' and she wrote '16-amps' on the microwave. I was impressed that Cindy used the EMS readout to manage her electrical loads, showing how the readout can be as equally important as the over/under protection.
