Buyers Guide For 50 Amp To 30 Amp Adapters

Not all RV parks in the USA have 50 amp service. If you have a 30 amp rig and are staying at a 50 amp park, it can be frustrating when your rig won’t power on or your batteries die early. This is where a 50 to 30-amp adapter comes in handy.

Adapters and converters take the form of a small box in which you connect your potential 50 amp RV to a 30 amp power source. There are several significant benefits to upgrading your RV’s adapter. Keep reading to learn about the considerations you need to make before getting one.

What To Consider When Choosing

When you’re looking for a 50 amp to 30 amp adapter there are things you should consider. Not all adapters are created the same, so here are the best way to find the right one for your needs


In order to convert 50 amps to 30 amps, the adapter must be robust. Power will be drawn continuously, so if the cables or adapter aren’t sturdy, it could lead to problems. Any combustible material placed too close to your hot adapter could be ignited if the adapter melted or if the wires melted and caused a short circuit.

Weather Resistance

The power adapter you use in your RV should be weather-resistant. With no cover, your adapter is vulnerable to the elements.

LED Indicator Lights

Power indicator lights made of LED are very helpful. To avoid wasting time and energy, you can first check if power is flowing by using this method.

Ergonomic Design

Power indicator lights made of LED are very helpful. So, you can check the electricity flow before testing any of your appliances.


Make sure you’re looking for a reliable RV adapter when you go shopping. Try to avoid the cheapest option. You don’t have to spend a lot of money, but you should read reviews and only purchase an adapter after making sure it has been put through its paces by a large number of RV owners.

Types of 50 Amp to 30 Amp Adapters

There are primarily two types of RV 50 amp to 30 amp adapters: dogbone and hockey puck. Let’s take a look at those in more detail.


An RV dogbone is a converter that lets you use a variety of different amp connections. Campers should always verify the amperage of an electrical outlet before plugging in their RVs. It looks like a dog bone in form.

A dogbone adapter is required to connect a 50-amp fifth-wheel to a campground’s 30-amp pedestal. Having a dogbone adapter for your recreational vehicle is a smart move. They’re reliable, affordable, and can withstand the elements.

Because dogbones can be locked, the extra layer of security they provide for your RV’s electrical system is substantial. O n the other hand, they do not boost performance. They merely provide a secure channel for data transmission. A dogbone adapter will not allow a 50-amp Class A motorhome to be plugged into a 30-amp outlet and function normally.

So don’t assume the same output from your dogbone adapter. As a result, the circuit may become overloaded. You also shouldn’t use an RV dog bone for an extended period of time. Finding shore power that has enough amperage for your rig is essential if you plan on staying in one place for several weeks or months. The dogbone adapter is only a stopgap measure.

Hockey Puck

In the same way that dogbone adapters transform the plug on your RV, so do puck adapters. Unlike a dogbone style adapter, which consists of a short length of cable connecting the two plugs, these tiny units (about the size of a small hockey puck) contain both the female outlet and male prongs required to make the conversion. This puck adapter allows you to plug the power cord from your RV into the pedestal and vice versa.

While puck-style adapters are more compact and therefore more user-friendly than dogbones, they do not offer nearly as many customization options. The increased size of these adapters means they can overheat, and their connections aren’t as reliable. Furthermore, they can cause significant twisting strain on an electrical outlet.

Generally speaking, puck adapters will do the job if you need to plug in your RV and the store is out of the “dogbone” adapters, provided you effectively handle the cord weight twisting problem. Puck-style 50 amp to 30 amp adapters will work for the weekend, but they aren’t a sustainable solution.

How We Chose Our Top Picks

Traveling is where we do the bulk of our studying. We looked into the most widely available 50 amp to 30 amp adapters on the market today. We compiled all the ratings, reviews, and suggestions made by our RV community peers, and finally, we made our final selections.


How does 50 Amp to 30 Amp dogbone adapters function?

There are actually two issues that the 50-30 amp dogbone adapter helps with. The primary issue is the dissimilarity between NEMA 14-50 and TT-30 connectors’ actual forms.

The NEMA 14-50 plug has a round ground prong and two flat prongs for the live and neutral wires. On the c ontrary, TT-30 has a round ground prong and two flat prongs for the live and neutral wires. The male NEMA 14-50 plug is too large to fit into the female TT-30 outlet. Dogbones with a female NEMA 14-50 connector on one end and a male TT-30 connector on the opposite end solve this problem.

The second issue is that the NEMA 14-50 connector needs two live wires, but the TT-30 outlet only provides one. A dogbone adapter solves this problem by connecting the slots for live wires on the NEMA 14-15 female connector.

Can a 50-amp RV be hooked up to 30 amps of shore power without causing damage?

Connecting a 50-amp RV to 30-amp shore power is safe, as is connecting a 30-amp RV to 50-amp power with the right adapter. However, it does have some restrictions.

The limited amount of power that the 30 amp shore power can supply is the first potential issue. In many cases, even though your RV is rated for 50 amps, you will need more power, such as when initiating both roof air conditioners that have more than 15,000 BTUs between them.

These days, many recreational vehicles have a fully automated energy control system that turns off appliances when there isn’t enough power to run them. But if your RV doesn’t have one, you’ll have to fill that role yourself.

First of all, if you have a 50-amp RV and is hooked up to a 30-amp power source, you should never run both air conditioners at once. Second, if your air conditioner has a BTU rating of more than 10,000, you should turn off all other electronics before turning it on. Finally, you must determine which appliance pairings are successful by switching them on and off while the air conditioner is operating.

Find out what other appliances, besides the air conditioner and the refrigerator, can be left on continuously.

What are the characteristics of a quality 50 Amp to 30 Amp adapter?

A high-quality adapter is worth the cost because it won’t break, short out, or supply insufficient power to your gadgets. Materials used in their construction typically feature flame retardant properties and resistance to ultraviolet light. These power converters have a stellar reputation because they strictly adhere to the strictest electrical standards. They may be a bit more costly, but remember that you’re working with electricity and should take all necessary precautions.

Think about your needs, the adapter’s safety features, and efficiency when making your selection. Protect yourself from shocks, electrocutions, and burns caused by touching a hot plug by using an adapter that is both durable and weather-resistant.

Is a surge protector with a dogbone adapter from 50 to 30 amps necessary?

Whether or not you are using a dogbone adapter, you should still protect your equipment with a surge suppressor. Lightning strikes or a problem with the power pedestal are both outside of your control. A surge protector can prevent damage to your RV caused by an unexpected jolt of electricity. It is important to note that dogbone adapters are not the same as surge protectors. Their uses are completely different from one another.

Final Thoughts

We’ve found that 50-amp to 30-amp adapters are indispensable on the road, and it’s likely that you’ll feel the same way. If the connections on your adapter are loose, it may be time for an upgrade. If you use an air conditioner, which consumes a lot of electricity, a loose connection can quickly become a problem.

Be sure to have everything you need on hand. Don’t leave home without a 50-to-30 adapter for your RV’s power needs. Our best wishes are with you as you travel to a new RV park on your next adventure.
