One Of The Best In RV Surge Protectors: Surge Guard By TRC

Technology Research Corporation, more commonly recognized as TRC, was founded in 1981 and was originally a military supplier of power distribution and management solutions. Having diversified their reach to the commercial market, TRC has become a recognized leader in RV surge protection.

You’ll find some pretty sophisticated RV power management solutions in their Surge Guard line. With offerings in automatic transfer switches and voltage regulators, they are best known for their 30- and 50-amp surge protection devices.

Newer portable Surge Guard SPDs come with LCD displays to give you vital information on shore power connections. All models come in portable and inline configurations.

More Than Surge Protection

The great thing about the Surge Guard brand is that it offers more than just surge protection. Inconsistent power fluctuations, intensity of electrical loads, faulty and worn connection points and the elements are real dangers to RVs, beyond the scope of what regular surge protectors can afford.

All Surge Guard models include protection from high/low voltages, open neutral conditions, pedestals that have been wired incorrectly AND surges.

The SPDs cut power if voltage levels fall outside of normal parameters, whether below or above. Normal levels fall between 102 volts and 132 volts; when fluctuations settle back within these ranges the power is restored to your camper with a time delay for A/C compressors to settle.

LED Indicator lights signal power supply and problems on the line(s). There is one light for each line (there are two lines to protect on 50-amp coaches) when the device is plugged in to a power supply.

Secondary indicator lights alert you when there is a delay in power or if there is something wrong with the wiring configuration, including bad grounding connections.

When the indicator lights stop blinking, the power is restored. There is a manual override to bypass the overload, under which you are still protected. The bypass is only recommended if you have everything turned off beforehand.

You also get multi-mode protection for cables running into your rig that protects you from potential power surges caused by electrical storms. Both 30-amp and 50-amp models have high ratings in Joules protection (up to 3850J) for these kinds of devices.

Installation

For portable models: it’s advised to plug your Surge Guard device into the pedestal before you connect your RV power cord to the surge protector. This allows the Surge Guard device to properly verify safe connections without causing damage to your rig.

There will be a 128 second delay in power connection to accommodate a/c unit compressor regulation. This is indicated by a flashing LCD that also verifies voltage current ratings.

Once the flashing light stops, you should have power.

During normal operation, the LCD screen alternates between two displays showing voltage and current levels and whether the power is on or off.

In a fault condition the LCD screen will display “Delay” and will restart after 128 seconds. Once that time has passed the screen will return to the normal operations display.

Should you come across a reverse polarity the display will read as such. This is a dangerous and potential shock situation and should be corrected immediately.

For inline models: if you are unsure how to hardwire your RV surge protector or if you aren’t comfortable doing electrical work, you should have a professional install the device for you. And actually Surge Guard recommends having a licensed professional or RV dealer install it. The following instructions are very generalized and should be followed with extreme caution.

While you have the option to hardwire protection for a power generator, this discussion is on protecting the power source only.

First make sure you are disconnected from the power source. The Surge Guard device mounts between the power source and your distribution panel. Position the SPD so that the lights are facing you and so that you will be able to read them easily.

If you need extra cable, be sure it is gauged to your power cord, probably 10 gauge. Cut enough cable length to adequately position the device, expose about six inches of the three wires (black, white, green) for easy configuration and strip about three-quarters of an inch of cable.

Black goes to black, white to white and green to the ground copper (if not green too). Repeat on both ends. Splice an end into the power side and the other into the panel side. Boom goes the dynamite and you’re done.

Obviously it’s a bit more involved than this, but this is the gist of it.

The TRC RV Surge Protector Range

With the increasing sophistication of technology, electronic components are becoming smaller and more sensitive to the power that supports them. When they undergo barrages of excess electricity they get worn down and eventually fail. These are the luxury items you find in your coach: microwaves, stereos, televisions and even refrigerators.

The TRC Surge Guard line is spans the realm of recreational vehicles from pop ups to five wheelers, all designed to control power conditions that may cause damage to your equipment.

Whether it’s surge protection or pole protection, Surge Guard has a list of special safety features to guard you from the possibility of damaging power issues.

Surge Guard protects your RV’s electrical system and any electronics you have running inside the vehicle when plugged into shore power. You should always, no matter what, have your RV protected when using power pedestals at RV parks. You never know what you are plugging in to. Campground power is some of the dirtiest and most unreliable resource there is and the first time you connect to a faulty pedestal and things go south, you’ll understand why this is important.

  1. We have been using a portable surge protector for about eight years, and have yet to have it stolen. That’s not to say it could never happen, just hasn’t happened to this point.

    We never, ever plug in without it.

  2. kenneth and joyce fisher says:

    we purchashed a model 34750 surge guard from camping world at robertsdale,al in 12-18-2009 and purchashed the extra protection plan and we have used it a total of five months of the year while in alabama for the winter and it isn’t used in the summer while in storage, this week it faulted and there is a problem with it, we are working with camping world and have made two trips to there at 40 miles each day and they are trying to get to the problem, my question is has there been any problems with this model ?

  3. Hi folks, Surge Guard used to have lifetime warranties but that changed when the brand was purchased by Coleman Cable in 2011 and now warranties cover one year only. This might be a reach, but if you still have the packaging or the receipt for the device I would check for type of warranty you had at the time of purchase. Otherwise, I’m guessing your extra protection plan with Camping World expires on December 18, two years after the one-year manufacturer warranty expires?

    As for that particular model, I have not ever heard of any problems with defects, though there’s always a chance for it. Was the device new at the time of purchase or was it a factory second or a used device? If new, my guess is you’ve plugged into a faulty pedestal and it fried your device. It’s really hard to say exactly without knowing the details of the event that triggered the fault and seeing the surge protector.
