Thoughts on the 'need' factor of a main line surge protector

What are your thoughts on a surge protector I have a 50amp hookup & the parts department highly recommended one. Not sure if because the just wanted to sell me something or if there are alot of issues with sensitive electronics or what?

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.


Care to explain why billions of homes and businesses in the US, Canada, Mexico, the world don't have their electrical equipment burned down to the ground on a daily basis?

Very few homes or businesses have any real surge protection or EMS and yet it is a very rare event.

Once again, an overblown RV ONLY subject with a piece of expensive equipment DESIGNED for RV USE ONLY at a price only a die hard RV enthusiast is willing to shell out for and claim because they have such equipment they have never had any troubles..

Yes, accidents do happen with electric items but not as much as it is over hyped, sort of like the latest virus issue..

I've been camping since 1971 and never had damage without one, until about 10 years ago. We were in a state park on a hot weekend and suffered numerous low voltage incidents and an outage or two. It took out a TV.

I bought and installed a EMS system and it detected problems several times since. It's insurance.

looks to me that that one is just a surge protector, not full function.

50 years of RVing and never used one. Lost a microwave once, not sure why. And we have traveled coast to coast and border to border and beyond.

I've got a hard-wired one (PI). I had a surge guard that plugged in, but I found it a pain and would often not use it. Likely at the worst times (rushing setting up in the rain etc.) Plus I camped at a couple of sites where I'd have to lay it on the ground to plug in.

Now with the hardwired one, there is no doubt I'm using it.

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.


If the voltage drops too low, then an autoformer might keep you going. I use one because I have seen low voltage many times.

I'm glad you put the qualifier "known" in your statement. In 13 years (all but the first 6 months with the EMS-HW30C) I have had no "known" surges either. However, it has disconnected me from power several times for low voltage, and once for high voltage. Surges are not the only problem. I still call this cheap insurance.

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.
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...


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.
I didn't have one for a long time, but decided to get one after reading about them - and only decided that it was a must have item after it did it's job at two different CG's. 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.
Experience without good judgment is worthless; good judgment without experience is still good judgment!

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...
