Like I said, those who have them were already convinced it was deadly out there and they just had to have that insurance policy. So these RV forum threads are heavily slanted so that it looks like the majority of the RV world has EMS. While I'm betting that is not the case at all, in fact just the opposite.
Some things get cumulative damage. You won't see the damage for a while after multiple exposures to low voltage. However, if you feel that you won't benefit, feel free to not buy one. Those who want to protect their investment are free to use one. I won't plug in without mine. (Actually, I can't since mine is hard wired behind the breaker box.) But I won't be insulted if you choose not to.
This breaks down into two camps. One camp points out what MAY happen and how. The other camp points out that it is a fairly rare phenomenon. Both camps are correct. Each user must decide for himself which camp he wants to join.

Its on my wish list, in the mean time, I have a monitor (displays voltage and checks for miswired) that I use to check before plugging in. I then plug it into the outlet near the sink so I can easily see it so if voltage drops too low I can turn off AC. It is not automatic, but it is what I have until I can budget the EMS.

In 14 years I've never had a known "surge" error with the RV. It might help but in my opinion you're likely waisting your dollars.

I would not want a TT with a pre-wired EMS - it would be bottom of the line like most of the stuff they install. And an electrical system is just as important on low end units as it is on high end units. I personally don't look to the RV industry to tell me anything - they just want my money. Heck you can buy slide out supports from Camping World. I'd rather listen to the opinions of people with actual experience.2012Coleman wrote:bpounds wrote:I think you got your percentages turned around. The progressive Industries EMS is so much more that a surge protector. I've been helped by mine more than once for stuff besides electrical surges. I won't go into specifics for all you 10 percenters...
Folks who have them, have already convinced themselves that you must get one.
Meanwhile, by my estimate the other 90% if us are getting along just fine without one.
Okay, your percentages are just as good as mine, since I just made up a number. I don't think we will find an RV industry survey to tell us the EMS ratio. Just observations is all I have, and I rarely speak with anyone who has installed one. My point above was, those who have decided that they are a must-have item, jump on threads like this. Those who don't, tend to not bother discussing something they don't find important.
Another reference point would be how rarely they are offered on new RV units as primary options. If typical folks felt strongly about that insurance, I'm sure the manufacturers would jump at the opportunity to offer an upgrade.
I'm sure an EMS is much more popular added to higher end rigs. There is a lot more to lose, so insurance becomes more desirable. An EMS is simply that - insurance. Some folks put more faith in it than others.

My question is how many joules are needed?
I suspect if lightning strikes near enough to put an impulse on the line, your surge is toast with the rest of your gear.
Likely never enough joules for lightning but might be OK for smaller electrical transients.
However, crossed wiring is a problem I have run into.
I've always carried a 50/30 adapter, 30/20 adapter and a common household tester which does the job. Not to likely a miswired pedestal when initially tested will change later...
