Surge Protector question - need advise - long - sorry!

When we purchased our new Outback (last week), we also purchased surge protector. It's a TRC Surge Guard Model 34730. Here's a link to their web site: TRC web site. Click here.

One thing that people at the RV dealership convinced us with, was to purchase the protector, but also warned that these surge protectors are subject to theft also. And after paying the "price" I sure do understand why!

Well, at our first campout this week-end, I used the surge protector. I ran a 30 amp extension cord from the pedestal to under the camper, plugged in the protector, then plugged in the camper to the protector. The actual device was under the camper, between the wheels on the passenger (right) side of the trailer. I did this thinking, "theft, theft, theft" all week-end.

Well, considering this was our maiden voyage, of course I was all over the camper this week-end. And to my absolute surprise, I found the panel that covers the electric (umbilical) cord to the camper, removed it and found out the umbilical cord is attached to a simple household junction box, and then (looks like) normal household wiring going from the (end) of the camper to the main power supply (converter) in the middle of the camper ... so this got me to thinking!

Rather than plugging the surge protector outside the camper (subject to theft), would it work if it was plugged "inside" the camper, inside this compartment where the cord feed into, and if the umbilical cord had a plug and the wire in the junction box had a plug, why not plug the surge protector in right there! It would be inside the coach, and in the event it ever failed, could easily unplug it and plug the original umbilical cord into the plug that would be attached to the coach wiring.

I could even build a new panel with a window so I could actually see the read-out on the surge protector and simply close the cabinet door when done.

So, here's the questions? Has anyone done anything like this before? TRC make in-line models. The only difference would be this has plugs instead of being "hard wired"?

If you have either the "in-line" model if you've found a way to "plug it in" inside your coach, how did it work out? Are you happy with it.

The down-side (only because I am very impatient) is, it has a 128 second delay, from the time the power is plugged in, until the protector let's the power on through.

Wiring it is no problem for me, but I will need to purchase a male and female 30 amp plug so splice into both lines.

What's your thoughts? Need advise from others who have used these surge protectors? Pros-Cons please before I go any further? Like I said, this is in the "thought" process. I've not done it yet.

  • That's the way I have mine it also keeps it out of the weather they are not water proof. Also I have 50 amp service and when it was the old way if I plugged into 30 amp service the power had to go through 25 feet of 30 amp cord then 25 feet of 50 amp cord before it reached the MH. Now if I use 30 amp it goes to pig tail to surge and leaves out the 50 amp cord.
    I say go for it.
  • I also have a Progressive Unit which I cable and lock to the post. Yes, with bolt cutters they can steal it, but why take a chance when there are many just plugged in. Since wiring is not an issue for you, consider a unit which is hardwire in.............As for the delays, the unit is going thru the process of making sure your electrical outlet is properly wire........
  • I installed the hardwired 50 amp version. I wired it in and installed behind my breaker box. Gives me a sense of security when I plug in. It did detect low voltage at a state campground and did not let the juice flow. Maintenance people thought I was crazy when I told them they had a problem because "none of the others in the campground had a problem". I just told them that the others did have a problem, they just didn't know it yet.
  • I hardwired my surge protector. However I did convert the cord to romex J-box into a plug & outlet. Mostly it just stays plugged in. But if voltage is dropping I can insert my voltage booster transformer. Works great and your protector could do same.

    x2 - never have to worry about a thing. Just this weekend my EMS-HW30C shutdown twice due to a low voltage condition.
  • Some units the delay time is adjustable. The delay is mainly to protect the compressor in your A/C unit. If your A/C unit has a built in short cycle protection you should be able to shorten up that time.

    Certain electrical loads if you drop them they need a few seconds to reset before you turn them back on, hence the delay.

    Does not matter where your surge protector is installed. The important thing is that you use it.
  • Your thinking is accurate.
    It will take some "doing" to intercept rewire the household junction box to add an outlet for your exterior surge protector to be in series with the circuitry, but it will work - providing you have the space.

    I have a truck camper and was worried about theft (we're going to Mexico!). So I squeezed the in-line surge protector in side the TC - just barely enough room.

    I should mention, as you probably already know, there is about a 140 second delay before the surge protector allows shore power to connect to the camper.
    Kind of a pain, that.
  • I've used a portable surge protector for the past 7 yrs. During the first couple of years, I was also very concerned about theft and would routinely cable lock it to the power pedestal. Then I got lazy and haven't locked it for the last 5+ yrs, still have it.
  • I have had a Progressive Industries unit ($400) for 8 years plugged into the pedestal in plain sight and Never stolen.
