The 34951 is the best 50 amp RV Surge Protector that provides the highest level of electrical protection for your RV, more than any other system on the market. This unit provides 4200 joules of surge protection, and the closest competitor is only 3580 joules of surge protection.
Now, you can add an 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).
The 34951 is also the only electrical protection system to provide not only line side protection, from the park 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 open neutral issues or elevated ground current 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 produced by the electricity coming into the RV from the source.
The 34951 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.
You won’t have to worry about how to secure your RV surge protector. This portable unit includes a locking ring to provide a theft deterrent and extra security.
The 34951 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)

The wireless display is great for when you are on 30 amp service which we are all the time in state parks. We monitor our usage and turn off things if we get close to 30 amps of use. This is the reason we went with the external protection instead of the internal one, along with the quicker access to power on this modle.
In my opinion, this unit is the best insurance money can buy for anyone with 50A service. Please don’t think I’m boasting, but I’m a power electronics engineering technician by profession so I have an intimate understanding of this stuff.
The biggest problem what I’ve seen at campgrounds is not necessarily voltage surges so to speak, but is a problem in the neutral connection which is more prevalent than one would think due to many, many pedestal electrical connections in any given campground. In a nutshell, what happens when you lose your neutral on a 50A service (most of which are two 120v lines which are 180 degrees out of phase from each other resulting in 240v between each phase) where you have two independent phases feeding your coach is that when a heavy load such as an a/c unit on one phase kicks in, it presents a very low impedance to that phase, causing the voltage to go very low on that phase. Damage may or may not occur to appliances on that phase. However, at the same time, the remaining voltage from the 240 volt total is applied to the other phase (much higher than 120V) and this high voltage will likely cause damage to anything on that other phase, especially anything with sensitive control boards and/or electronics.
This unit immediately senses this condition and disconnects your coach from all power before any damage can occur.
This unit also senses most other kinds of power irregularities that might happen to your coach and immediately disconnects you before damage can occur.
I’ve been putting mine through many testing scenarios since my wife and I just purchased a costly new fifth wheel and it has yet to let me down. I’m very impressed with its’ performance and after much research, I truly believe this is the best unit on the market today.
I opted for the wireless monitor which, I truly love being able to see what’s going on from inside my coach without having to go out to the pedestal.
Money very well spent in my opinion!...
Additionally, you won’t beat the price and support from TechnoRV!
I recently purchased this for my 5th wheel. The first time I plugged it up, it detected a faulty ground in my RV cable. I double checked the cable with a VOM and the cable did have a ground issue. I also like purchasing items from Techno RV. They not only know their products but they stand behind them after the sale. Happy RVing
