What to Look for When Buying an RV Transfer Switch
Motorhome owners know that only a best RV transfer switch will do if they want to power their RV’s essential devices during an outage or when shore power is unavailable.
Unfortunately, newbies often find it confusing and challenging to choose the right transfer switch for their campers. Here are some of the most important things you must look for when buying an RV transfer switch.
Amps and Wattage
You must look for two things when buying an RV transfer switch: your camper and generator’s amperage and wattage ratings. In general, the device should closely match your rig and generator’s power specifications.
Most campers today have either a 30-amp or a 50-amp system. If you are not sure about your vehicle’s amperage rating, it would be wise to check the manual. Choose a 30-amp transfer switch if you also have a 30-amp generator and camper electrical system.
When it comes to the wattage, it is often better to pick a transfer switch with a higher wattage rating than your RV generator’s operating wattage. For example, a 5-kilowatt device would be ideal for a 5,000-watt RV generator. It would even be better if you can get a device with a higher wattage rating.
It is crucial to get the amperage and wattage ratings right to avoid any problems, like RV transfer switch failure and electrical issues.
We are talking about a device that bridges at least two power sources and your motorhome’s electrical distribution center. You will want a transfer switch that is not only efficient but also safe. A malfunctioning RV transfer switch can produce disastrous consequences to the unit, your vehicle, or anyone from your family.
It would be ideal to buy a UL or CUL-certified transfer switch. If the product does not have this certification, you can check if it has accreditation from other reputable organizations that test and certify products against safety standards. You will have greater peace of mind knowing your device will not explode in your face, provided you install it correctly.
I also recommend reading customer reviews. They may not be authoritative sources, but they can give you an insight into the device’s real-world performance. Take note of any safety issues that customers may raise. You can check other reviews to verify if such safety issues are isolated cases or are serious concerns.
It would be better to buy a transfer switch that already comes pre-wired. It makes RV transfer switch installation more straightforward and more affordable, too. Purchasing a non-pre-wired device requires you to buy additional wires.
One of the most significant advantages of pre-wired systems is ensuring the right wire connection to the device terminals. There is no need to consult the RV transfer switch wiring diagram because the manufacturer already did it for you. The only work you will do is connect the wires to the generator, the shore power unit, and the breaker panel.
You will want every transfer switch component to be of the most robust and most durable materials if you expect the device to last many years.
Do not be swayed by ‘heavy-duty’ labeling. Some companies put the term on their label even though it is not heavy-duty. You will have to research the design materials used in the manufacture of the transfer switch.
Durable transfer switches minimize the need to purchase a replacement device or part. In addition to the cost, disassembling and reassembling the system can be tedious and bothersome.
Most buyers always look at the warranty information because it gives them an idea about how much the manufacturer believes in their product. A company that offers a two-year warranty may suggest that it stands by its transfer switch only for up to two years. You are on your own beyond that.
On the other hand, a switch with a 10-year warranty tells you that its manufacturer trusts its product quality. It is willing to answer any issue that may occur within the warranty period.
Camper transfer switches can cost you between $50 and $200, on average. I suggest working with a more realistic budget to make your transfer switch purchase more worthwhile.
Other Important Factors to Consider
Here are a few more factors that you can consider when buying a transfer switch for your motorhome.
Transfer Switch Type
Transfer switches are either manual or automatic. Manual ones are less expensive, although they can be cumbersome to operate. You will need to flip a lever to switch between the two power sources – generator or shore power. It can be frustrating to find the switch in the middle of the night without a flashlight.
Automatic transfer switches do all the work for you. They continuously monitor electric parameters. If they sense an impending power outage, the system automatically starts the generator. It gives you electricity the moment your RV loses its electric power.
Ease of Maintenance
One issue about transfer switches is creating a brief arc every time the device switches between power sources. It can lead to problems with the transfer switch contact points.
The device should have a design that minimizes the creation of an electric arc. It also makes RV transfer switch troubleshooting easy. If the device does not have this feature, it would be best to clean the contacts easily.
Time Delay Feature
An important feature to look for in a transfer switch is the time delay. It overrides momentary outages that may result in a false generator start. It protects the system, ensuring optimum function in the long-term. It would be nice to have an adjustable time delay mechanism to set the feature to a shorter time than its predetermined delay.
Frequently Asked Questions (FAQs)
Does my RV have a transfer switch?
Modern and high-end RVs often have a factory-installed transfer switch to improve vehicle safety and provide continuous power to the vehicle’s electronics. If you are unsure, you can check for its presence.
The primary function of a transfer switch is to direct power to your vehicle’s electric distribution panel. You should see a box anywhere between the circuit breaker panel, the backup generator, and the shore power unit. You should see three large wires, two going into the box and another going out.
If you see neither the box nor the wires, your RV may not have a transfer switch.
How big of a transfer switch do I need?
If you refer to a transfer switch’s physical dimensions, you should consider the area where you will install the device. It should be big enough to allow for adequate ventilation inside the box. It should also be small enough to fit in tight spaces.
If by big you mean the transfer switch’s electrical capacity, you should look at your generator’s load. Your chosen transfer switch should have an amperage rating that is the same as your generator. As for the wattage, you can get a transfer switch with a higher wattage rating than your generator’s. Check the device’s voltage compatibility, too.
What is the life expectancy of an automatic transfer switch?
An automatic transfer switch for RV can last up to 100,000 operations or about 20 to 25 years. However, maintenance and product quality can impact this device’s operational lifespan.
Neglecting standard upkeep procedures can shorten the product’s lifespan by several years. Mediocre-quality transfer switches might only last less than a decade.
Hence, RV owners must exercise caution when buying a smart transfer switch for their motorhomes.
Are automatic transfer switches safe?
Yes, automatic transfer switches for battery backup are safe. These devices feature state-of-the-art logic controllers serving as the system’s brains. This component monitors the electrical frequency and voltage of primary and secondary or backup power sources to determine when it must activate the transfer protocol.
Logic controllers have multiple electrical connections, such as fuse blocks, connection terminals, power sources, and power disconnects in various form factors and configurations. The transfer mechanism is also a crucial component of an automatic transfer switch.
Unfortunately, not all brands have similar manufacturing processes and quality control procedures. Some companies might use substandard components, undermining the automatic transfer switch’s safety.
Haphazard manufacturing practices might also produce a defective ATS that fails in its principal function.
Hence, RV owners must be diligent in researching an automatic transfer switch’s technical specifications and real-world performances.
Can you bypass an automatic transfer switch in an RV?
Yes, RV owners can bypass an automatic transfer switch in a motorhome. Some automatic transfer switches have a bypass isolation contactor technology, allowing users to flip a switch to reroute the electrical energy from the ATS.
Unfortunately, most RV automatic transfer switches do not have this feature. In such cases, RVers can disconnect the transfer switch’s electrical wires and connect shore power to the main electrical cable supplying the motorhome’s circuit breaker.
However, many RV experts discourage this practice because of the potential safety risks involved.
How different is a 30-amp from a 50-amp RV transfer switch?
The most significant difference between a 50 amp transfer switch and a 30-amp unit is their voltage-carrying capabilities. An RV transfer switch 30 amp model can only accommodate a maximum of 120 volts, equivalent to about 3,600 watts (120 volts x 30 amps = 3,600 watts).
On the other hand, a 50-amp switch has two 120-volt prongs for a combined voltage rating of 240 volts. Hence, one can expect a 50-amp switch to handle as much as 12,000 watts (240 volts x 50 amps = 12,000 watts).
This difference applies to both automatic and manual RV transfer switch units.
How do you hook up a generator transfer switch to an RV?
Hooking up a generator transfer switch to your RV is easy, although it may require some elbow grease.
Open the generator transfer switch and look at its wiring configuration. Most products come with a schematic to simplify wiring installation. Take note of the location of the shore power, generator, and circuit breaker terminals. Determine the location of the hot bus, ground bus neutral bus, and other components.
Turn off all RV power before you start hooking the transfer switch. You may need to remove the electric outlet for the shore power, replacing it with the transfer switch. Connect the generator wires to the correct terminals in the transfer switch. Do the same with the shore power wires before securing the circuit breaker wire to the transfer switch.
Turn on the power of your RV. Let it run for a while before plugging your RV into a shore power outlet. You should hear a clicking sound. Turn on your generator. You should hear another click after about 30 seconds. Turn off the generator, taking note of a click. It is a sign that you are successful in hooking up a generator transfer switch to your RV.
Cover the transfer switch and secure it in place.
Do you need a transfer switch for a portable generator?
Portable generators do not need a transfer switch. However, it would be wise to have one. It is mainly useful for whole-house generators. It helps in the safer distribution of power to your appliances during an outage, ensuring the continuous operation of even your hardwired appliances and devices.
Without a transfer switch, you will have to connect your portable generator directly to your grid power service panel. Doing so increases the risk of frying your appliances or damaging the portable generator. You might even endanger electric utility workers who may be in the area fixing the power lines because of the surge.
