This 30-Amp transfer switch has a straightforward installing process, which makes the task manageable. In addition, rig owners have reviewed it as more accessible than their past installations of transfer switches.

If you are an experienced RVer, installing it would be a piece of cake. Else, we’d still recommend getting the services of a certified electrician because there are components to handle with experience.

The Go Power! The 30-amp transfer switch has impressive durability. The manufacturer used heavy-duty materials in the construction of this transfer switch. Which not only increases its already long-life span but makes it sturdy too. Giving it an advantage over competitors by a large margin.

The transfer switch was also successful in getting the UCL certification. It is a necessary certificate, as it is proof of the rigidness of the product. In addition, it shows that the product passed rigorous tests before its sale.

With this, you can sit back and relax because you shouldn’t worry about its performance at all. It is a 3-way RV transfer switch that all customers love.

It can handle both the shore and the generator power sources, thanks to its automatic design. So, when using it, you should have no issues switching it between these two.

Technology Research 40100 Surge Guard ATS

This surge guard is an actual 50 amps transfer switch that can meet your needs without any trouble. This, when combined with its features, makes RV owners admire this switch.

It can deal with faulty power sources with such excellence that it leaves everyone impressed. In addition, the users of this transfer switch were impressed with how well this switch could utilize the campground’s sketchy shore power.

This is achieved by a special feature in the switch, The time delay feature. It delays the voltage from the power source, hence ensuring the power supply is stable before entering the rig.

This isn’t the only feature that saves your rig. It has another feature, too, that is mechanical interlocking contractors. These contractors ensure that the two power sources do not enter the RV at once and offer protection against short circuits and surges.

The installation process is relatively easy for the Surge Guard’s Automatic Transfer Switch. Not only for long-time RV owners but for newer owners too. Installing it was not like banging your head to rocks. This is thanks to the detailed manual included in the package.

One thing in this product disappoints me. It is the plastic body of the switch. This can reduce its lifespan a lot. So, if you want to buy a product that lasts longer, this might not be it.

Pros

  • Perfect for sketchy power lines.
  • Easy and clear instructions.
  • Quality materials used inside.

And in each pole, it can withstand up to 50 Amps. Moreover, it is an automatic switch that switches to the generator simply by starting the backup generator.

Although it is a sturdily built transfer switch, it still has a whopping 22 seconds delay. This is because the transfer switch gives generators enough time to warm up. In preventing the generator from starting under load, it saves your appliances from malfunctioning.

It is a sturdy build transfer switch that weighs above 7.5 pounds. Again, it’s because of the metal construction. It has a heavy-duty relay assembly that increases its durability. In addition, it is a UL and CSA-approved transfer switch that shows RVers’ trust in it.

The JONASK 53A isn’t only just an automatic switch. It has dual mode, hence ‘dual power.’ It can be automatically switched or with the help of a manual switch.

This manual switch is a simple operation, but it gives reliable performance. As a result, it is quite useful in uncertain situations where the automatic system starts malfunctioning.

This is a heavy-duty transfer switch of up to 63 amps. It is designed for bigger trailers, where you have all the luxury accessories. This transfer switch supports up to a 7 KW load at once.

Overall, the body is of high-quality plastic, but still, it doesn’t give a sense of durability. It feels as if the plastic will age quickly. Unfortunately, you can’t be sure if it’ll last long enough to be called long-lasting.

How to Choose the Best Transfer Switch for RV

Wattage and amperes

There is a huge variety of RV transfer switches in the market. But you don’t have to worry about them, as we’ll help you with it. It’s not hard to find one that fits your requirements.

To choose the transfer switch for your RV, check the wattage on your generator. For example, if your generator runs at, say, 2000 Watts, you should get a transfer switch with at least 2000 Watts.

But we’d recommend getting a transfer switch that has a higher wattage capacity than your generator. If you end up getting a lower wattage transfer, it’s as if you’re inviting trouble.

As for the amps of your Transfer Switch, there are two types, one with 30 amps and the other with 50 amps. Get one that fits your generator and rig.

Configuration status

Transfer switches are mostly pre-wired. But some of them aren’t wired, and those are the ones that you should avoid.

So, check thoroughly before getting a new transfer switch. Not only are the pre-wired transfer switches easier to install, but they also cost less to install too.

Safety

Safety is a huge factor in RV transfer switches. If the thing you are buying to keep yourself safe isn’t safe, how can you assure your safety?

You need to make sure the transfer switch that you’re buying is safe enough or not. They cause terrible accidents if any of their parts malfunction. So, a pro-tip is to get a safety switch that is certified.

Installation factor

When getting a transfer switch, you need to consider its installation factors, too, such as where you will mount the switch. And if it’ll need extension cords or not, where will be the inlet box?

If you properly consider these things when getting a transfer switch, you won’t find yourself running to the electric store repeatedly.

Construction

Sellers won’t usually mention the construction of a transfer switch. So, that’s why you have to check if the construction of the transfer switch is durable or not?

With this, you can be sure that it’ll last a long time without the need to replace it. In addition, you can examine its materials to make sure it’s durable.

If the seller is good, he’ll offer you options such as a normal or ‘heavy-duty.’ You should still check the components and their build quality. If you get your hands on an actual heavy-duty, it guarantees that it’s the last longing.

FAQs

What are the different types of transfer switches for RV?

Transfer switches vary in manual and automatic. The types of transfer switches for RV depend upon the voltage needed. They can range from 30 amps to 100 amps.

And if you want to go for higher power, you can find one from 2KW to 20KW depending on your needs.

How does an RV automatic transfer switch work?

Transfer switches that are used in RVs prioritize generators. Usually, the switch will be connected to shore power even when no power is present.

But when there’s a voltage detected on generator inputs, it will drop to the shore power. These switches are made so that only one input can be connected simultaneously; this prevents any hazardous conditions.

Where is the transfer switch in an RV?

A transfer switch is positioned right before the breaker panel in the RV, hidden inside a cabinet or on the wall behind some object like the refrigerator.

How big of an RV transfer switch do I need?

You will need to calculate the load of your generator used in the RV, and for that, you need to match the largest outlet of your generator to the transfer switch. This will help you get the transfer switch of the size your RV requires.

How do I choose an automatic transfer switch?

The best way to choose an automatic transfer switch is to know your requirements. First, check how much load your generator has.

Then, make sure it can supply current for a reasonable amount of time, like 3 to 4 hours straight. Also, the current rating should match the use by the main breaker.

Conclusion

Leaving the comfort of homes is a significant accomplishment. It gives you enough time to think about yourself without any worries. But, of course, this can quickly change if you don’t prepare enough.

So, we recommend you get yourself an RV transfer switch for backup power. So, that fun can carry on even when power runs low.

Now, before getting one, read the whole guide thoroughly. And jot down essential points off it. So, when you go out to get a transfer switch, you won’t be fooled by the salesman.
