I installed my Progressive Industries EMS-HW30C today, the install went pretty smooth, the product looks well-made and very good instructions with it as well. I took my time and looked things over thoroughly before cutting the cable. The trailer is a little too far from an outlet at my house right now but I will take my generator up and give it a try tomorrow, I made up a plug for my generator as well with the neutral and ground bonded. It will be nice to know the trailer is protected now. Here is a link about running a generator with an EMS and checking for a floating neutral http://www.progressiveindustries.net/videos
