The 34931 provides the highest level of electrical protection for your RV than any other system on the market. This unit provides 2400 joules of surge protection.
Now, you can add a inside monitor to this unit so you can always see what is going on at the pedestal, from inside of your RV! (Inside monitor not included, and is sold separately, model 40301)
The 34931 is also the only protection system to provide not only line side protection, from the pedestal, but also provides protection on the load side. This means that if you have power faults occurring from wiring issues or equipment failures inside of the RV, this system will protect you. Any elevated ground current issues in the RV will be detected and your RV will be cut off from this in an instant. This unit also protects you from frequency issues.
The 34931 analyses the pedestal to ensure there are no issues with open ground, open neutral,reverse polarity, or high and low voltage issues. This analysis takes place in 10 seconds, the closest competitor takes 136 seconds to perform a similar function. The system also has a 128 second reset function just in case your air conditioner goes into reset mode.
Includes a locking ring to provide a theft deterrent.
The 34931 has a lifetime warranty that includes connected equipment coverage. This mean that if this unit fails to do what it was intended to do and damage occurs to equipment in your RV that Surge Guard will pay for those damages. (Click here to see warranty information for more details)

I have only used these two products at two different campgrounds so far on our ~ 6000 mile trip, but I am impressed with Total Protection Surge Guard, as well as the optional Wireless Display. Within 10 seconds the 34931 (30 amp) analyzed the pedestal and provided clean 60 cycle 118 volts to my rig. The 40301 Wireless Display is so convenient to keep a check on the operation of the Surge Guard and my power consumption at the press of a button ... rain, or shine, there is no reason to walk to the pedestal to check the readout for any errors ! Happy that I purchased these units and would recommend them to others !!
