RE: Which EMS Surge Protector

Far more damage is caused by low voltage than surges. I'd go to the fully featured Hughes autoformer with surge protection. Be aware that there is some controversy surrounding RVs and the use of autotransformers. The National Fire Protection Agency (NFPA) stated a ban on the use of autotransformers due to the dangers they place on the campground’s electrical service. NFPA Code: NFPA 70 Article 551.72 (E,F) states, “The use of autotransformers shall not be permitted. The use of listed surge protectors shall be permitted.” Many campgrounds already ban the use of autotransformers, and more could do so in the future as a result of NFPA 70. If you have an autotransformer, sometimes referred to as an autoformer, it may be a good idea to ask the RV park that you are staying at if it is okay for you to use it at their facility.

RE: Which EMS Surge Protector

I suspect that the damage you experienced came from a loose connection and not a "surge." All kinds of things are blamed on surges but in reality they are rare. Actually, the day it happened at the campground the power went off twice because of a large accident on the road near the campground. Those in our group who did have surge protectors did get reports that there was a surge on one of the two times the power was restored and the inverter did not keep our frig working on the way home from that trip. We noticed no heat in the bedroom 2 trips later.

Which EMS Surge Protector

Just got our RV back from the repair shop! We had a 5th wheel for 10 years then changed to a motorhome 5 years ago. We had our first electrical failure in October. The Surge, or whatever, fried our inverter and the circuit board that ran the heat in our bedroom. The cost was over $1,000, but only cost us the $100 deductible on our insurance. We made our first post on this on 10/6/20 and have been doing a lot of research since then. One possibility was the hardwired Progressive EMS-HW50C. Then we started thinking about the post mounted EMS-PT50X so that we could check out the campground wiring before pulling out the extension cords. After further research we have added the Southwire 34951 to the list. As we understand it, the Progressive units have been around for about 10 years, so there are a lot of posts about them. The Southwire 34950 has been around only 2 or 3 years, so far less posts, and the 34951 is the new upgrade that includes a remote Bluetooth monitor. There is a TechnoRV article that does a good job of comparing the two units: Do you need an rv surge protector If we understand our research so far, both post units are about the same, Southwire costs a little more, Progressive take about 2 minutes to analyze the power while Southwire can do it in 10 seconds. A big question to the group is: TechnoRV gives their gold star to the Southwire unit, does anyone know if the two companies are in any way related? And of course; what are your opinions of the two units? Progressive EMS-PT50X vs Southwire 34950/34951
