Video Transcript for Camco RV Wiring - Power Adapter - CAM55312 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.

I send you picture installation

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!
by: Ronhileman07/13/2018
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.

Unfortunately, we have still not hit the road, so I cannot anything new.

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 .

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: Arthur06/23/2020
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
by: Randy S01/22/2016
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: Charles, Knoxville TN12/28/2017
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: Pat J01/16/2020
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: David 05/21/2023
Just what I wanted.
by: Walter05/25/2018
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: KHR09/29/2017
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: jeff l.09/19/2017
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: Bob C.06/09/2019
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: William02/16/2018
Very straight forward, simple protection for my TT. Good size for ease of use.
Grab handles are a must.
by: Ron C.03/15/2019
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: Rick M12/13/2020
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: Robert P09/06/2016
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: James06/09/2017
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: Urben09/07/2018
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: M.G.02/14/2017
A must have for your RV. Cheaper than the damage that can be done with a bad electrical surge!!!
by: David11/19/2020
So far, I have had no electrical problems from voltage spikes or other electrical abnormalities so in this case, 'no news is good news'.
by: Rick11/20/2017
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.

See what our Experts say about this Camco RV Surge Protectors
- Does Camco RV Power Defender Circuit Analyzer 30 Amp Item # CAM55312 Reset ManuallyThe internal circuit board of the Camco RV Power Defender Circuit Analyzer Dogbone - 125V - 30 Amp Item # CAM55312 will shut down the flow of power if it senses a spike or other dangerous condition, and won't allow the power to flow again until the problem is corrected or the voltage drops down to a safe level. There is no way to manually reset it.
view full answer... - Could 50 Amp Power Defender be Used on Trailer that Has 30 Amp PowerYes you could use the 50 amp power defender part # CAM55306 that you referenced on your 30 amp trailer but it wouldn't start protecting the circuits until more than 50 amps was put on the circuits. A better option would be a 30 amp power defender part # CAM55312.
view full answer... - How to Connect Surge Protector When Using 30 Amp to 50 Amp RV Adapter Power CordYou have it exactly right. Starting at the RV you will plug in your 30A power cord like # A10-3025ED90 which will connect to the 30A surge protector, such as the Camco # CAM55312 or the multilevel # CAM55301. Then from the surge protector you will use your adapter like # A10-5030FHVP to plug into the 50 amp shore power outlet.
view full answer... - Recommended Adapter and Surge Protector for 50 Amp System to 30 Amp Shore PowerWith your 50 amp camper system, I recommend using the Power Grip RV Power Maximizer - 50 Amp Female to 15 Amp Male and 30 Amp Male # CAM55025 to allow you to plug into 30 amp power supplies. Then you will use a surge protector like # CAM55306 for multiple surge protection or # CAM55313 for single time surge protection. Many people use the Camco Power Grip Cable with Lock # CAM44290 to protect their investment. Unless you convert your entire system to 30 amp, I don't recommend using a...
view full answer... - Which Camco RV Surge Protector Will Protect from Multiple UsesThe 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. This has same 1 year warranty.
view full answer... - Circuit Protector for RV That Protects Against High and Low Voltage 30 AmpThe 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.
view full answer... - Adapter Needed To Plug A 30 Amp Trailer To A 50 Amp Outlet On A HouseThe 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.
view full answer... - 30 Amp Trailer Compatibility with 50 Amp Extension CordYou can still use your 50 amp extension cord to the outlet and just use an adapter like the Mighty Cord RV Power Cord Adapter Plug - 30 Amp Female to 50 Amp Male - Round # A10-5030AVP. 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. You may want to consider the a circuit defender...
view full answer... - Camco Power Defender 30A Compatibility With 50 Amp ServiceYou cannot plug the Camco RV Power Defender Circuit Analyzer Dogbone - 125V - 30 Amp # CAM55312 into a 50 Amp service with an adapter like the Power Grip RV Power Cord Adapter w/ Handles - 125V - 30 Amp Female to 50 Amp Male # CAM55175. It will essentially trick the analyzer and it won't function properly. You need to plug the analyzer directly into the power source with the correct amps to get a proper reading.
view full answer... - What Material is the Camco RV Power Defender Circuit Analyzer Made of?The Camco RV Power Defender Circuit Analyzer # CAM55312 is made of weather-resistant PVC and polycarbonate. This is highly durable and sturdy material so you do not have to worry about the interior components of the circuit analyzer getting damaged. I've added a link to a video review of this part for you to take a look at.
view full answer... - Multiple Power Surges Through the Camco RV Power DefenderThe 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.
view full answer... - What Can the Camco RV Power Defender DetectThe Camco RV Power Defender, part # CAM55312, can detect a correctly wired circuit, an open ground, reversed polarity, open neutrals, hot/ground wires reversed, and if the wire is hot on neutral with the hot open, as well as if the hot wire is open or if there is no power. The manual goes into more details of these individual states and how to interact and proceed when detected.

- Surge Protection of Camco RV Power Defender Circuit Analyzer, Part # 55312The surge protection on the Camco RV Power Defender Circuit Analyzer, part # CAM55312, is 2,100 joules.
view full answer... - Using the Camco RV Power Defender as an Extension CordThe Camco RV Power Defender, part # CAM55312 isn't intended to be used as an extension cord. Its overall length of 27-1/2 inches can extend the distance a little bit, but its intended use is to protect your RV against faulty wiring and as a surge protector.
view full answer... - Differences Between the Two Camco RV Power Defender UnitsThe 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.
view full answer... - Difference in Circuit Protection Between Camco 55310 and 55312 Power DefendersThe 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.
view full answer... - Recommended Power Adapter and Surge Protector for 50 Amp Campsite to 30 Amp RV ConnectionYou have it correct. From the RV connection, you will use the 30 amp female to 30 amp male power cord like # A10-3025ED90. Then you will have your 30 amp surge protector like # CAM55312 for single surge or # CAM55301 for multiple surge with automatic reset which is what I recommend. Then you can use an adapter like the Mighty Cord Dogbone RV Power Cord Adapter - 30 Amp Female to 50 Amp Male - 12" # A10-5030FBK to connect to the campsite power service.
view full answer... - How To Use 50 Amp Surge Protector On 30 Amp Trailer with 30 Amp ServiceThe 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.
view full answer... - Recommended Surge Protector for 30 Amp TrailerFor 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...
view full answer... - 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...

- 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.

view full answer... - 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...
view full answer... - 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
view full answer... - Does Camco RV Power Defender Circuit Analyzer CAM55312 Shut Off Power During Power Surge/Low VoltageCamco RV Power Defender Circuit Analyzer # CAM55312 will shut down power if there is a power surge. But it does not shut down power if there is low voltage detected.

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