Video Transcript for Camco RV Power Defender Circuit Analyzer Dogbone Spec Review

Today we're going to take a look at the Camco RV Power Defender Circuit Analyzer Dogbone with the surge protection. This circuit analyzer will plug into a 30 amp receptacle at an RV park to test for improper wiring. Has a 125 volt circuit analyzer which will protect the RV from any improperly wired electrical boxes and power surges. It will protect your RV from power surges up to 2100 Joules. On the very front of the box, right here, it has the diagnostic lights that will indicate faults before you connect your 30 amp electrical cord to your RV. When you plug it in, there'll be a light up here and it will tell you that it's surge protected. Then it'll show you how to read the combination of lights to tell you what circuit is being affected, if any.

If you notice on the handles, they have these nice, sturdy, built-in handles on both ends to make unplugging very easy. Right up here, the 30 amp male end, this is what'll plug into the 30 amp receptacle at the RV park. Down here is the 30 amp female end which will connect to your RV's 30 amp electrical cord. This is a nice weather resistant PVC and polycarbonate which will protect the electrical components. If you notice on each plug-in, it is yellow in color which makes it very easy to see in any low light conditions. A few specs on this.

I want to give you the overall length of the cord from one end to the other. It's going to be right at 22 7/8 inches. The wire gauge that they use in this is 10 gauge wire. That should do it for the review on the Camco RV Power Defender Circuit Analyzer Dogbone with the surge protection.

It was a great, easy transaction purchasing from etrailer! The item came in a timely fashion, as told... and the item works like it’s supposed to. Very happy with my purchase, and I’m confident if I had any questions or concerns, a quick call or email will take care of my concern(s). The video review of this dogbone surge protector was very, very helpful in my search for what I needed for my camper. I will buy again, I’m positive!

Product has worked great! I’ve purchased another one for a fellow camper friend, as well!



by:

This appears to be exactly what I was looking for. I have not had a chance to use it on the road yet, but I connected it to our hookup at home, that I wired myself, and was reassured to see all of the correct lights light up. When I hit the road, I will be a first timer, and everything I have read strongly recommends testing circuits prior to hooking up and using surge protection. This device does both.

The camco power defender came much earlier then was promised . I placed my order late one evening the next took a phone call from entrailer.com c/s. The nice lady said the power defender was on back order and would be probly two weeks before they received the order and they would ship it out the same day . Sounds reasonable right ! Well here's what happened .... Five days after placing the order a package showed up from etrailer , I assumed it was the rest of the order that was in stock ( 2- tail lights and a vent lid ) but to my surprise it was the full order ! Plus the way it was packaged was nothing less then overkill which is nice to see now days . Maybe 8 lbs of product in a box rated for 100 lbs ! Now the reason that impressed me so much is , im a retired contractor from one of the largest small package companies in the world . Everyday I saw product being shipped in sub par packaging . Even shipped in the box that was ment to be displayed in the store . So to me this is kind of a big deal ! After all those years of my customers asking if I ran their package over with my truck . When it's the shipper that just doesn't care and trying to save a couple bucks this is quit refreshing ! As for the power defender , ask me in about 30 days after my wife I return from our first camp outing of the season . We have been staying in campgrounds we new had good power but now the kids are out we're heading to other places .



by:

The item is much bigger than I imagined. Seems to be heavy duty. I intend to use it during the first week of July at a campground. The most important thing for me is that it will provide information and protect my trailer electronics.

No problems. Just used it for six weeks in a row on a long trip

Hello etrailer. I rate the RV power defender and locking cable we recently purchased at 5 stars each. As a beginner RV owner, I was looking for something that was simple to understand yet confident it would do the job. The Camco 30amp Power Defender was the perfect answer. In fact, my wife and I are currently sitting at our campsite and I’m looking at the unit that shows the surge protection is on and the 30 amp campsite wiring is correct.



by:

Hooked the 30amp dogbone with surge protector up right away, to the outlet I installed outside my house for my new camper. Anytime I hook up my new camper to a 30amp outlet it's going to be good insurance to know that the circuit is wired correctly! Great product... Best Price at etrailer! Excellent service.... thanks etrailer and Karen! I compare prices when it comes to trailer, or RV equipment. Consistently, etrailer has the best prices on the same exact items . Also, most of the time the purchased item arrives much faster then I was told it would take to get to me. (Most of the time I don't pay for delivery.) Thank you! I've been a happy customer for over three years.



by:

Mostly bought this to pretest outlet before plugging in my camper. It has 3 led lights on it that show the condition of the outlet. This part works just like one of those little outlet testers with the 3 lights that we have all seen for standard 20 amp outlets. It also says it has a Surge Suppressor. I can not comment on the operation of this part of the product. (How would you know if it worked?) " It does do a great job of pretesting the outlet and I have found many 30 amp plugs in campgrounds wired with the hot and neutral reversed. Even the 50/30/20 RV box I purchased at Home Depot was wired wrong. It's cheap insurance. I recommend it.



by:

Been trailer camping for 2 years without a surge protector and electric system diagnostic tool. Glad to have one for protection and piece of mind.



by:

So far I’ve not had a problem with this protector. Comforting to know I’ve got the trailers circuit protected. I have not had an issue with a campgrounds electric hookup so I haven’t seen it indicating a bad circuit. Easy to use and read and has worked well in the rain. We’ve used this at a fox or so campgrounds and several times for about a week. Price was great and would purchase again



by:

Fit my needs perfectly. Great product. Nothing blew out so far. We had a few lightning storms and a couple of close hits. Everything survived. Including a deeply covered, in our little queen size bed, a spastic shivering Golden Retreiver that hates water and storms.



by:

Had a surge protector that failed. etrailer replaced with no problems. As always I will come back when I need more items. great to work with.



by:

Customer recently at RV park when lightning strike caused voltage spike, damaged several circuits in RV. A must for protecting RV AC electrical. Also analyses AC circuit quality at the RV park panel, before plugging RV into panel.



by:

Great product. This is the second Camco RV Power Analyzer that I have purchased, to give this one to a friend. And, etrailer sells these (and all their products) at a super price. Add that to the great customer service given by etrailer, and you can’t go wrong. Always love getting the things I need at etrailer.com!



by:

we plan on using this product every time we use our travel trailer to make sure our electrical connections are safe to use, very glad to have this



by:

Very easy to use with a easy 3 light diagnosis to let you know the electrical source you are plugging into is wired correctly.



by:

Very straight forward, simple protection for my TT. Good size for ease of use.
Grab handles are a must.



by:

Calling e- trailer is like calling a friend, curtious , friendly , and aim to please. Haven't used any of the items from my order yet, I will shortly . The order was on time and wrapped so good nothing was damaged .I will definitely call e- trailer for my next order.



by:

Received the correct part as ordered. The part was double box packed, and arrived in good condition. Im unable to rate at this time as my trailer is in storage. It appears to be heavy duty and well made, will find out in future when its put to use. Thank you for your service it was easy and pleasant purchase experience with etrailer.



by:

This is a very well made product. Not only is it a surge protector but has the added benefit of verifying proper wiring connections. This feature comes on handy when you are hooking up to unknown or newly installed electric sources. Very good value.



by:

A must have for your RV. Cheaper than the damage that can be done with a bad electrical surge!!!



by:

Another good investment. No more worries with bad wiring or grounding at the pedestal. Also easy to lock around the pedestal for piece of mind so it doesn't walk away.



by:

Just what I wanted.



by:

The product works the way it should and the shipping was also great

  • Can A 50 Amp Surge Protector Be Used On A 30 Amp Application?
    The best option is to use a 30 amp surge protector like the Camco RV Power Defender Circuit Analyzer Dogbone # CAM55312, but if you really wanted to use the 50 amp surge protector # SU99SR you'll just need to use the: -Mighty Cord RV Power Cord Adapter - 30 Amp Female to 50 Amp Male # A10-5030FBK with the Mighty Cord RV Power Cord Adapter Plug - 50 Amp Female to 30 Amp Male - Round # A10-3050AVP. The reason you'd want to not use a 50-amp surge protector with your 30-amp trailer is because...

  • Air Conditioner Circuit Breaker Trips when Using Camco RV Power Defender Circuit Analyzer CAM55312
    It is possible that there is a short inside of the Camco RV Power Defender Circuit Analyzer # CAM55312 that is causing the circuit breaker to trip. In that scenario you would have to replace the Analyzer. It could also be that the AC is trying to draw more power than the CAM55312 can handle and in doing so is causing the breaker to trip. This analyzer is rated for 125 volts and 30 amps so if the power draw is beyond that then it can cause some problems.

  • Differences Between the Two Camco RV Power Defender Units
    The difference between the Camco RV Power Defender 30 amp, part # CAM55312 and the Camco RV Power Defender 50 amp, part # CAM55313 is the amperage that they work on. The 50 amp variant is built for higher power drawing RVs, while the 30 amp is designed for lower power RV's. You'll want to match your particular plugs and required amperage to your RV when choosing which product to buy.

  • How To Use 50 Amp Surge Protector On 30 Amp Trailer with 30 Amp Service
    The best option would be to switch to a 30 amp surge protector like the Camco RV Power Defender Circuit Analyzer Dogbone part # CAM55312. That said, you can use your 50 amp surge protector with a few dogbone adapters, the Mighty Cord Dogbone RV Power Cord Adapter part # A10-5030FBK and Mighty Cord RV Power Cord Adapter Plug part # A10-3050AVP.

  • Recommended Surge Protector for 30 Amp Trailer
    For your 30 Amp trailer you will want the Camco RV Power Defender Voltage Monitor - 30 Amp # CAM55301. This will monitor voltage and automatically disconnect when dangerous levels are detected and then reconnect when voltage stabilizes. This is a great option to allow protection from multiple surges. You may want to consider the Camco Power Grip Cable with Lock # CAM44290 to secure your investment. If you were to use a 50 amp unit, then there could be spikes that could damage your...

  • Troubleshooting A Camco Dogbone RV Surge Protector
    It definitely could be a burnt out light or some other internal issue with the Camco RV Power Defender # CAM55312, but the only way to really test that theory would be to connect to an outlet that had an open ground or neutral to see if the red light kicks on and the left yellow light remained off. I don't recommend testing this as you could potentially cause an electrical fire. Unfortunately Camco doesn't make it to where you can actually fix any issues with the # CAM55312 and at this...

  • Circuit Protector for RV That Protects Against High and Low Voltage 30 Amp
    The Camco RV Power Defender Circuit Analyzer # CAM55312 does not protect against low voltage, but there is a similar product that does both low voltage and surge protection. It is the Camco RV Power Defender Voltage Monitor # CAM55301. It disconnects power in a dangerous voltage situation and will reconnect when voltage gets to the 102 to 132 volt safe range.

You will still need a 30 amp cable like the Mighty Cord RV Power Cord with Handle - 30 Amp Male to Twist Lock Female Connector - 25' Long # A10-3025ED90 or if you have the retractable hardwired cable then you just use the adapter to utilize your extension cord.

  • Does Camco RV Power Defender Circuit Analyzer have a Circuit Breaker Reset Delay
    Camco RV Power Defender Circuit Analyzer # CAM55312 only can tell you, by way of light indicators, if a circuit is working or not and a probable issue. The internal breaker does not have a manual switch to reset it so it will continuously cycle with minimal delay if tripped.

  • Which 30 Amp Camco Surge Protector will Reset Itself After Triggering
    The Camco RV Power Defender, part # CAM55312 can only withstand a single surge. It cannot reset its surge protector once its used, and will need to be replaced. There is a version that will reset itself though and for that part number you'd want # CAM55301.

    The Power Defender, part # CAM55310, is referred to as a voltage analyzer where part # CAM55312 is called a circuit analyzer but essentially it's the same protection. The difference is that # CAM55310 protects up to 1,050 joules while # CAM55312 protects up to 2,100 joules.

  • Recommended RV Surge Protector Voltage Regulator for 30 Amp Power System
    For any trailer or motorhome system, I recommend using a surge protector to protect your trailer electronics and components from issue. For your 30 amp system I recommend at least the Camco RV Power Defender Circuit Analyzer Dogbone - 125V - 30 Amp # CAM55312 which will protect from a single surge has indicator lights of faults. This will require replacing after a surge and will not allow you to safely reconnect your system after a fault so you would be taking a risk if you reconnect....

  • Can the Power Grip Generator Detect Wiring?
    The Power Grip Generator Plug, part # CAM55333 can't detect wiring or power surges. You'll want a better match for that application, which would be Camco's RV Power Defender, part # CAM55312

  • How to Protect CAMCO # CAM55312 Power Defender RV Power Supply Analyzer Against Theft
    The best way I can think of to lock the Camco # CAM55312 Power Defender would be to use a cable lock like # 8122D. If you can pass a few wraps of the cable through the handle of the male plug and get the cable tight enough that it can't be unplugged, it would provide some deterrence against theft.

  • What Does Open Ground Error Code Mean for 30 Amp Shore Power Socket
    A single yellow light on the Camco RV Power Defender, part # CAM55312 that you referenced indicates an open ground like you can see on the picture I attached. This is typically caused by a broken wire or bad connection in side the socket/plug of your generator. So what this means though is that your 30 amp power socket can STILL work since your electrical path is between the hot and neutral pins. The ground is a path in case of a short in equipment. So basically you don't have as safe...

    The Camco RV Power Defender Circuit Analyzer Dogbone - 125V - 30 Amp # CAM55312 isn't a 50 amp to 30 amp adapter so you would actually need an adapter like the Mighty Cord RV Power Cord Adapter - 30 Amp Female to 50 Amp Male # A10-5030FBK to be able to draw 50 amps and adjust it to 30 amps for your trailer.

  • Blue Light On Camco RV Power Defender CAM55312 No Longer Illuminating
    I spoke with my contact at Camco regarding your RV Power Defender Circuit Analyzer # CAM55312. He said that if the blue surge protector light is no longer illuminating on your unit then it has experienced a surge episode (and protected your RV!). This may have happened with your 30 amp home outlet or it could have happened the previous time you used the analyzer at a campsite. Since this particular model provides one-time-event protection, it is no longer able to provide surge protection...

  • Does Surge Protection in Camco RV Power Defender Circuit Analyzer Dogbone CAM55312 Re-Set
    The surge protection in the Camco RV Power Defender Circuit Analyzer Dogbone # CAM55312 provides one-time-event protection. I confirmed this with my technical contact at Camco. For a re-setting surge protector you will instead want to use their # CAM55301. This unit will re-connect automatically when a voltage surge downs back down to a nominal 102-to-132-volt level.

  • Which Camco RV Surge Protector Will Protect from Multiple Uses
    The warranty length of the Camco RV Power Defender Circuit Analyzer # CAM55312 is one year and it protects you from manufacturing defects. This has a one time circuit protection like a fuse. If instead you wanted something that will protect for multiple uses we have the Camco RV Power Defender part # CAM55301 which automatically resets like a circuit breaker.
