On the other hand, the model advantages and high quality make it a solid performer, which is very difficult to compete with.
A Caring Maintenance of Your Generator
As analogous electric devices, this switch offers an electric protection of a certain level. And considering its suitability for a garage or basement installation due to the small size it was logical for the manufacturer to equip the switch with anti-dust and anti-dirt protection. With that, the Generac also took care of your generator maintenance. To help you avoid your generator overload, this power switch offers two watt-meters, each showing the power consumption for one output phase: A and B. These meters will come in handy to control the power draw. To run the generator in a normal operation mode and avoid its overload, please ensure that total power demand of the appliances energized does not exceed the generator capacity. If you use one of the circuits to feed power hungry appliances such as freezers or well pumps, you will probably need to switch the phase connection from your generator from time to time to balance the load. As a general protective measure, we recommend to always keep the power consumption differential within the 1,000W limit for the phases.
More Power — More Capabilities
Evaluating the performance of this particular device, it is safe to say that its ability to feed the circuits from generators with up to 7,500W output offers a great opportunity of keeping a large variety of critical appliances powered up from your auxiliary source. In most cases, people are seeking the capability of the switch to power up their fridges in case of an outage so that to keep the foods from defreezing. It is also common and rational to look for a switchgear capable of supplying power reliably to a heater during the wintertime, and this model can do just that. Moreover, with such switch capacity along with the most crucial equipment, you can even connect your TV, radio, or a PC to your power generator.

What is a Transfer Switch?
Probably, each of us has experienced a sudden power outage. However, nobody wants to get immersed in the darkness which is the most apparent consequence of an outage in case it occurs after dark. For example, if you have your power utility out for hours your foods in the fridge may get defrosted, and what is worse, some foods may go off. In case you use an electric burner for the cooking, you will have to go to bed with an empty stomach. The worst scenario is having your guests invited for a barbecue party that never happens due to no electric power supply.
What Features to Compare
Switching to the Backup Source
To pick the right switchgear, first, you need to get familiar with its main specifications. To start with, transfer switches have two ways of switching to the backup source: manual and automatic.
In most cases, manual electric transfer switches are cheaper, smaller, and easier to install. However, when using them it takes more time to switch to the supplementary power supply. The automatic ones do the switching in a few seconds or quicker, which is crucial for certain establishments like hospitals, where lives of patients often depend on an uninterrupted operation of the medical equipment. In such cases, an automatic switching equipment is the only choice.
The next two crucial values for our switching apparatus are the maximum power (Watt) of the generator used and its maximum amperage. The peak power consumption defines the number and electrical load of circuits you can power simultaneously via the switch. The same applies to the maximum amperage. For example, if you own a big facility, and power outages are a frequent issue, you will need a more powerful generator as well as a piece of switching equipment with a high amperage rating to establish an uninterrupted power supply. The number of circuits to supply is another concern. Note that the transfer switch may be connected to more circuits than your generator can power at a time, and being able to cut off and turn on again the non-critical ones prevents the generator from overloading. To enable that your switch must have enough branch-rated circuit breakers.
Pay attention to the adequacy of protection of the transfer switch body to the environment you are going to install it in. The NEMA standards were developed for evaluating this correspondence. The NEMA 1 devices are designed for indoor usage and come with an antisplash protection. While the conformity with the NEMA 2 also implies the equipment suitability for indoor usage plus a limited waterproof. If the switch conforms with the NEMA 3 it means it was designed for an outdoor use and is protected from dust, rain, and sleet. Such switches are also protected from getting damaged caused by icing.
Q: What does a short warranty term imply?
A: Well, the five reviewed models are not the only power transfer switches, and some analogs have a short warranty. The point is that the device itself encounters numerous electricity transients and mains outages that result in wearing out its wiring and all the crucial elements. Therefore, you can't rely on a switch with a short warranty coverage because there is always a risk of the switchgear failure when the current operating conditions exceed the design parameters even marginally.
Q: Manual or automatic?
A: It depends on your expectations. Of course, a manual switch is not what you're looking for when purchasing a power switch for a big facility. On the other hand, an automatic switch is not a must to power your house if you don't have any appliances that can't survive an outage or a transient.
Q: How do I prevent the backfeeding?
A: All the transfer switches we've picked for the review are open transition devices, meaning they prevent the backfeeding. Setting them to the 'off' position (with a circuit breaker) cutts off the power supply from both mains and an auxiliary source to connected devices. Nevertheless, closed transition switches with backfeeding have their special application.
Q: How do I know what appliances should be connected to a double pole?
A: Always read the label on the electrical equipment you're connecting to the circuit. In general, all the appliances, which generate or absorb the heat (burners, freezers, etc.) or provide a mechanical force (water pumps, vacuum cleaner) have a high power consumption and work with high voltage supply (240V). Other devices like your TV or PC will get enough power from a single pole circuit.
Q: What tools do I need to install a transfer switch?
A: In most cases, you will need a power cord, an inlet box, a wire connector, and a plug end. Some switches have the inlet box built in. Thoroughly read the package description and look for the availability of these items as you may need to purchase something additionally. And, of course, you will need your household tools for the installation.
Q: What about the device safety and protective measures?
A: According to common knowledge, you must not expose your switch to water, dust, or dirt if has no appropriate protection (pay attention to the NEMA standard). It is also suggested to name each circuit so that you don't get confused about the wiring, even if your model is automatic. Don't install your switch with the reach of small children. Always keep track of the power demand when the generator is running as you need to prevent its overloading.
