  • Where Should The RV Surge Protector Be Plugged In When Using An RV Power Cord Adapter
    Hi Bernadette, You would want to plug your 50 amp to 30 amp adapter in to the power pedestal and then connect your Portable Power Watchdog Surge Protector # HU42VR to the adapter. Once the Watchdog lights show that the connection is good you can connect the trailer power cord to the surge protector. If you don't have a 50 amp to 30 amp adapter you can use the # A10-5030FBK.

  • Can 30 Amp RV be Powered from 50 Amp Power Source
    It's very common for people to use a 50 amp power source on a 30 amp camper like what you are trying to do. Basically you'd want to use the 30 amp surge protector after the dogbone 50 amp to 30 amp adapter like the part # A10-5030FBK that you referenced. This protects your 30 amp RV from overdrawing.

  • 30 Amp to 50 Amp Connector Option
    Hi Mike! We do carry 30 amp to 50 amp adapters, but unfortunately, we don’t have one with both a 90-degree angle and a female twist-lock connector. That said, we do have the Mighty Cord Adapter part # A10-5030FBK it’s a 12" long adapter that lets you connect a 30 amp female plug to a 50 amp male shore power source. If you can share a little more about your setup and what you’re trying to do, just drop a comment below—I’d love to help you find the perfect fit!

  • Recommended 240v 50 Amp to 120v 30 Amp Adaptor
    I spoke to my contact at Valterra and found that the # A10-5030FBK steps down a 50 amp service receptacle (2 X 120VAC) to 30 amps supply. This would work great for your camping trailers electrical system. I have linked the above mentioned product to this page for your convenience.

  • Does Mighty Cord Adapter # A10-5030FBK Reduce 240v to 120v?
    Never fear! I went ahead and reached out to my tech at Valterra (the manufactures of Mighty Cord products) and she confirmed that the RV Power Cord Adapter # A10-5030FBK takes the 240v down to 120v. This this factor, it is fine to use with a 30-amp RV.

  • 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.

  • Recommended 4 Prong to 3 Prong Power Adapter for RV
    Since you have a 3 prong plug on your trailer, I assume you have a 30 amp system. For adapting to a 4 prong plug you would then use the Mighty Cord Generator Adapter for RV Power Cord - 30 Amp Female to 30 Amp Twist Lock Male - 12" # A10-G30430VP. If you instead want to connect to a 50 amp 4 prong plug then you will use adapter # A10-5030FBK. We don't have any female to female adapters to if you need a longer cord you will simply use an extension.

  • Can 2019 Lakota Living Quarters Horse Trailer with 30 Amp AC Unit Draw Power From Campsite
    30 amp service is very common at campsites. You'd have no problem attaching directly to the power supplies at the sites. Let's say you were at a campsite that only had 50 amp power supplied though, in this situation you could use the part # A10-5030FBK and you'd be set. Having more power than needed won't hurt anything. Your AC would only pull the amperage it needed.

  • How To Use 50 Amp Surge Protector On 30 Amp Trailer with 30 Amp Service

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.

  • Will The Watchdog Surge Protector Still Work If You Use A Y-Adapter To Get Power
    The Power Watchdog Surge Protector # HU27FR is just there to cut the power to your RV in the event that the voltage drops below 104v or surges above 132v to protect the electronics is your RV. Changing how the RV gets that power won't affect it as long as it stays within that voltage range. For example, if you were at a campsite with 30 amp service and used a 50 amp to 30 amp adapter like the # A10-5030FBK your RV would only be getting 30 amps and the surge protector would still function...

  • Adapter Needed To Plug A 30 Amp Trailer To A 50 Amp Outlet On A House
    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.

  • 30amp to 50amp Adapter Cable For RVs
    30amp is 110v and 50amp is 220v. 30amp plugs will have two flat prongs and a rounded ground prong. 50amp plugs will have 3 flat prongs and a rounded ground prong. If you're trying to plug a 30amp power cord from your RV into a 220v power source I recommend the Mighty Cord RV Power Cord Adapter - 30 Amp Female to 50 Amp Male - 12" Long Item # A10-5030FBK.

  • Will 50 amp to 30 amp Adapter be Okay to Use with 50 amp Source and 30 amp Converter
    Using a 50 amp to 30 amp adapter like the part # A10-5030FBK will be totally fine for your application. The 50 amp power source will be 240 volts and the 30 amp will be 120 volts but the adapter cuts the voltage down to correct number and the extra amperage won't be an issue either.

  • Recommended RV Extension Cord and Adapter for Mini RV
    We do have a 20 Amp extension cord available, which is the Mighty Cord RV Extension Cord # A10-G20253E. In order to use this you will need to have a twist lock plug on your mini RV. Unfortunately there are no 20 Amp adapters that will work for you. That being said, I recommend verifying that 20 Amps is correct. It would not be the first time someone was given the wrong information and you want to make sure you have the right equipment. More than likely you need a 30 Amp and not a 20 Amp....

  • Is the Mighty Cord 30 Amp Female to 50 Amp Male Adapter Rated for 30 Amp 120V or 30 Amp 240V
    The Mighty Cord Dogbone RV Power Cord Adapter # A10-5030FBK is exactly what you are looking for. It only utilizes one of the pins on the 50 Amp side so the 30 Amp side is only rated for 125V (also known as 120V). Attached is a review video for you to reference as well.

  • 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 # 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.

  • Recommended 50 Amp RV Cable With 50 Amp Twist Lock Female To 30 Amp Male Connector In 50 Ft Length
    It sounds like you want a cord to run from a 50-amp recepticle on a shore power pole to the 30-amp power cord on your RV. For that purpose you could use the Mighty Cord # A10-5025EH 50-amp extension cord. Add to that a Mighty Cord # A10-5030FBK power adapter to go from 50-amp down to 30-amp to attach to your RV 30-amp power cord. The cord on your RV is probably 25 foot and this extension is 25 foot, totalling 50 foot, the maximum distance to run a 50 amp cord.

  • Camco Power Maximizer for 50-Amp RV That Has Access to Only 30-Amp and 15-Amp Service
    We offer many RV wiring adapter items that can allow connecting 50-amp devices to 30-amp service at an RV park. I think the item that was mentioned to you is the CAMCO Power Grip RV Power Maximizer # CAM55025. This is a Y-type adapter cord that on one end has a 50-amp female connector for your RV and on the other end two separate connectors for 15- and 30-amp service. By connecting the two lower-rated plugs to the RV park power access you end up with a total of 45-amps of current for...

  • Electrical Cord and Adapter to Connect 50-Amp Motorhome Power Inlet to Standard Household Outlet
    Motorhome 50-amp male power inlets require a cord with a 50 Amp Twist Lock female plug like the one on the Mighty Cord 25-foot # A10-3050EDBK. But since the other end of this cord has a 30-amp male connector, not a 15-amp household supply male connector, you will also need a dogbone adapter # A10-1530HVP to give you the standard 120V male plug to connect to a household outlet.
