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.

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. 453604

Hard to say anything negative, I haven't experienced any issues that I would need the defender for. It does give me a solid piece of mind knowing it's there though. 409560

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! 506114

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. 541060

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

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. 512939

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. 235988

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. 762748

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 738778

Ask the Experts about this Camco RV Plug Adapters

  • 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...

  • 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.

  • 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. This has same 1 year warranty.

  • 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...

  • Does Camco RV Power Defender Circuit Analyzer Reset Itself After a Surge
    Camco does make a version of the Camco RV Power Defender Circuit Analyzer Dogbone # CAM55312 that does automatically reset itself with the Voltage Protector part # CAM55301 but the part # CAM55312 will only take one surge before it needs to be replaced. It's like a fuse whereas the Protector is like a breaker in that it resets. I attached a review video for the Protector for you to check out as well.

  • 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.

  • 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.

  • Multiple Power Surges Through the Camco RV Power Defender
    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.

  • Does Camco RV Power Defender Circuit Analyzer CAM55312 Shut Off Power During Power Surge/Low Voltage
    Camco 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.

  • 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.

  • What Can the Camco RV Power Defender Detect
    The 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.

  • 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.

  • Camco Power Defender 30A Compatibility With 50 Amp Service
    You 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.

  • 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.

    I attached a picture that has the lighting codes of the Camco RV Power Defender, part # CAM55312 explained. Two yellows mean correct wiring, one yellow most likely means you have an open ground on the outlet at your house. Is there another outlet you can try to verify if the outlet is the problem.

  • 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.

  • 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.

  • Using the Camco RV Power Defender as an Extension Cord
    The 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.

  • Are the Ends of an RV Surge Protector Replaceable
    It would not be smart to replace the female and or male end on any electrical extension or adapter. If a short occured to the point where an end was burned and or melted then it will be imperative to replace the entire unit as there is most likely something else that has shorted that would either not allow the extension or adapter to work or cause another failure, perhaps more catsophic than the first. I have attached a list of our RV wiring adapters for you. Let me know if you need...

  • 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.

  • Comparison of Camco Circuit Analyzers and Voltage Protectors
    Camco Power Defender voltage protectors, parts # CAM55301 and # CAM55306, have a bit more protection than the circuit analyzers, parts # CAM55310, # CAM55312, and # CAM55313. Both the analyzers and protectors have diagnostic lights for faults but beyond that the analyzers are just surge protectors. The voltage protectors go a little further by detecting the voltage and shutting off if the voltage level falls below 102V or goes over 132V. The voltage protectors also reset themselves...

  • Recommended Power Adapter and Surge Protector for 50 Amp Campsite to 30 Amp RV Connection
    You have it correct. From the RV connection, you will use the 30 amp female to 30 amp male power cord like # 277-000147. 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.

    With 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...

Then from the surge protector you will use your adapter like # A10-5030FHVP to plug into the 50 amp shore power outlet.

    For any trailer or motorhome system, I recommend using a surge protector to protect your trailer electronics and components from issue.

  • Hooking Up Surge Protector for 30 Amp Camper to Plug Into 50 Amp Power Source
    If your camper is wired for 30 amps I highly recommend using a 30 amp surge protector. The potential issue with using a higher-rated 50 amp surge protector is that it wouldn't be triggered soon enough to protect any appliances you have that are rated for 30 amps. To hook up your 30 amp camper to a 50 amp power source you will want to first connect a 30 amp voltage protector (like the Camco # CAM55301 for a reseting protector or # CAM55312 for a one-time-use protector) to the camper. Then...

  • Does Camco RV Power Defender Circuit Analyzer 30 Amp Item # CAM55312 Reset Manually
    The 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.

    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.

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...
