Best Transfer Switches Buying Guide
Not too sure what to look for in a transfer switch? Our buyer’s guide can help you there!
When it comes to transfer switches, there are two types: manual and automatic, which we shall look at now.
Manual transfer switches allow you to change the power sauce manually, simply with the flick of a switch! You can switch from grid to generator power easily. Manual switches tend to be cheaper than automatic transfer switches.
These switches must be flipped during a power outage too, which does not need to be done with automatic switches. Manual switches are easy to set up as there is no programming and fewer parts than their automatic counterparts.
With manual switches, you can control the loads to ensure that your generator does not overload. They are a popular choice with many people; just be sure to flip the switch in an outage!
Automatic transfer switches allow you to switch your power from the grid to a generator automatically. These are more convenient and can be programmed to power the highest priority circuits during a blackout, so there’s no running around flipping switches!
These convenient switches are more expensive than manual switches. They usually have a higher maximum wattage, an excellent choice for those after higher power.
To kit or not to kit?
When purchasing your transfer switch, it's always a good idea to opt for a comprehensive kit. These kits will ensure that the installation is quick and easy, usually with all the parts included.
These days, most transfer switches are sold as a kit. Be sure to check before purchasing so you can ensure your switch can be installed once it has been purchased!
When selecting your transfer switch, be sure to check the number of running watts it can support before purchasing. You will need to work out which circuits you want to be powered through your transfer switch and the total number of watts it will take to run them.
Selecting a transfer switch that cannot support watts’ amount can lead to complications down the line, with the switch being overloaded and possibly blowing!
Most transfer switches will operate on and with 120V, so be sure not to overload the voltage too! Keep an eye out for more powerful transfer switches that can also handle 240V if you need the extra voltage!
Always check the warranty of the transfer switch before purchasing, as you would with any electrical item! As a general rule, you will usually see a 2-year warranty on transfer switches. A warranty will provide you with peace of mind as you use your switch and ensure you are protected should anything happen!
Be sure to keep the warranty documentation and user manual close by in case you have any issues. Alternatively, these days most manuals are online. Simply type in the name and model of your switch, and a downloadable manual should appear!
When purchasing any electrical item, you want to know that it is safe for use in your home or business. Look out for transfer switches that come with UL/CUL certifications to ensure your switch is up to code.
Most transfer switches should come with these certifications and should be listed in their product descriptions.
When it comes to transfer switches, the price can vary dramatically, leaving you wondering just how much you should be spending on your new switch. Despite the price range, you don’t need to spend a fortune to get an excellent quality transfer switch!
Be sure to set a clear budget and stick to it as closely as possible. You may want to consider what you want from your transfer switch to help you set this budget.
For example, do you want a waterproof switch that can be used outdoors? Are you willing to pay more for a more extended warranty period? Considerations like this will help you narrow down your choice and set a realistic budget.
Remember, you don’t need to conduct a bank heist for your new transfer switch; there is one suitable for every budget!
Frequently Asked Questions
Get your last-minute queries answered here!
Do I need a transfer switch for my generator?
Transfer switches aren’t always necessary, but you must use a transfer switch when it comes to using a portable generator in the home. The National Electric Code requires you to have a correctly installed transfer switch when using a portable generator to power appliances in your home.
If you want to sell your home, this is essential. Poorly installed switches, or none at all or a code violation, can land you in some hot water! Not worth the risk!
Transfer switches are also easy ways to power your home in a power outage, as you will simply switch over to a generator without the need to fiddle about with cords in the dark!
It is also safer than using extension cords, which can back-feed power, increasing fire or electrocution risk. Installing a transfer switch can avoid all of these and provide a less stressful experience in a power outage!
How do transfer switches work?
Transfer switches stop your utility power and generator power from operating at the same time. In a power outage, plug your generator into the transfer switch and turn on the generator.
Once powered up, flip the transfer switch to the generator position, and the generator will power your essential circuits.
Usually, you can select which circuits should be powered too for complete control! A transfer switch works to provide safe power to your home in the case of power outages or extreme weather.
What is grounding?
Grounding refers to the electrical circuit being connected to the earth. Grounding provides internal insulation for any electrical failures in circuits that can cause dangerous voltage levels, which can cause fuses to fail.
It also reduces the build-up of static electricity, but this is more so in large telegraph or power transmission circuits than your smaller transfer switch. Grounding is often an activity best left to an electrician to ensure it is done correctly and safely.
However, if you do want to do it yourself, you can follow the steps below. Remember that these are just a guide and if you are unsure, consult a professional electrician.
- Locate the panel box and select where you want to mount your switch. It is best to do this near your panel box for an easy installation.
- Mount the transfer switch to the wall, ensuring it is secure and free from any obstructions.
- Locate the main electrical panel and turn off the power. Check the power is off by testing with an appliance.
- Connect the wires from the transfer to the breakers you want to control in the panel box.
- Using a drill bit, drill a hole through the house wall from the outside. You can feed the wires through this hole. We would recommend a 1 ½ inch drill bit to do this.
- Install the included electrical box above the hole outside.
- Run the electrical cable from the electrical box, through the hole you made, to the transfer switch.
- Use the electrical receptacle included with your switch and connect it to the outdoor box’s electrical cable. You can mount the electrical receptacle to the box following the instructions your kit came with.
- Connect the other end of the same electrical cable to the transfer switch inside your home.
- Ensure your generator is working before testing your work! Be sure to check the oil and fuel levels too.
- To test, leave your mains power off and plug your generator into the outdoor electrical receptacle.
- Flip your transfer switch from line to generator. Check the connected circuits are receiving adequate power from the generator.
- If everything works, your installation has been successful! If not, you may need to make some adjustments, check all the connections are secure. Do this while the power is off to avoid electrocution!
- Once everything is working, flip your switch to its original position and turn your generator off.
- Turn your mains power back on.
- Finally, seal your hole to ensure bugs and any moisture cannot enter. You can do this with some wall filler.
Transfer switches are nifty pieces of equipment to have, especially if you are prone to power outages! As you can see, there are plenty of great options on the market that won’t break the bank!
Whether it is an automatic or manual switch you opt for, be sure that it is certified for use and easy to install! Remember that while you can install the switch yourself, it is always wise to seek professional help, especially if you are a transfer switch virgin!
