When the Power Goes Out!
When the power goes out, you can rely on Reliance to have the product you need. Specializing in transfer switches for portable generators, Reliance Controls offers a wide range of innovative and reliable transfer switches and accessories available.
What Is A Transfer Switch?
A transfer switch is an electrical device that allows you to safely connect a generator to your household wiring. It is permanently installed near the service panel in your home to make using a generator as safe and easy as operating a light switch.
Why Do I Need One?
During a power outage, there are two ways to use a portable generator for power. The first is to run extension cords from the generator to your lights and appliances. However, this is inconvenient and does not allow you to operate some of your critical circuits like the furnace fan or well pump. The second way to use a generator is to connect it directly into your household wiring. Using only one cord, you can now power several or all of your most important household circuits, including the furnace fan and well pump. To do this, the National Electrical Code requires a transfer switch. Direct connection without a transfer switch can result in damage to your home and generator and great harm to utility workers.
How Do Transfer Switches Work?
A transfer switch prevents the utility power and the generator power from powering your household circuits at the same time. When the utility power goes out, you simply plug your generator into the transfer switch, start it up, and flip the transfer switch or switches from the Utility position to the Generator position. The most important circuits in your home are now powered by the generator.

Clearly labeled circuit wires for quick load center connection. Each circuit has a red and black wire. The red is connected to the existing circuit breaker in the main load center. The black wire is connected via wire nut to the load wire for that circuit. |
Large, three position, light switch style toggles to control your appliances. Switches are normally kept in the 'line' position while utility power is on. When the power fails, toggle the switches to 'Gen' position to enable generator power (patented). |
Built in junction box for hardwire installation to save time and cost. (patented). |
Overloading the generator causes unnecessary wear and tear and can damage the engine or appliances. The use of watt meters to monitor the loads on the generator helps prevent overloads and understand efficiency of the system. |

There was a problem filtering reviews right now. Please try again later.
We bought the transfer switch capable of supporting 10 circuits from Amazon. Delivery took about a week and the unit was well packed with no damage.
The unit is solid and heavy duty.
Installation was very easy and took a total of 4 hours, start to finish. It took longer to run the cable to the outside connector plug than anything else.
After carefully mapping my current circuit breakers so that I knew exactly which breaker affected which lights, outlets, and etc. it was time to decide which circuits we would backup. Since the transfer switch supports 240 volt connections and our generator is capable of 10KW peak we were able to divide and balance the load across the two 120 volt legs based on normal and peak power requirements. It took awhile to get the balance figured, then we made a map identifing each circuit breaker and each backup circuit. The drawing is now covered with plastic and on the wall next to the main panel. We also wrote out detailed instructions on how to activate the system and how to transfer back to commercial power. Pretty easy but when the power is out you need to make sure you don't make simple mistakes, like not grounding the generator for example.
I know most of what I have said doesn't really address the product but it is useful information for anyone contemplating such an installation.
The transfer switches (there are 10) are rugged clearly marked and each has its own circuit breaker. Each circuit is clearly identified by a letter A through I. Using a tape machine I added labels showing which circuit each lettered transfer switch connected.
A very nice feature is the power meter for each leg of the 240 circuit. If you have an imbalance you will see it and be able to turn switches off to see the effect. In the end, if you didn't get the balance correct the first time, you can drop circuits to keep running and then decide how to move circuits later.
The wires were all clearly marked and were stranded copper so they were easy to route. As I wired each circuit the following procedure was followed:
1: Main power off.
2: Selected circuit off.
3: Red wire to circuit breaker.
4: Black or Red hot wire from breaker connects to the black wire from the transfer circuit with a wire nut.
5: Main power on.
6: Checked that power was still off at selected circuits in the house. Lots of running around ....
7: Selected breaker to on.
8: Checked that power was returned to the selected circuits in the house.
9: Repeat steps for remaining circuits.
I could have simply wired all the circuits once the main power was removed but by doing it this way I double checked my initial mapping of the house. In my case everything was perfect. If I had made a mistake in my map it would have been more difficult to fix the problem later.
After grounding the generator I connected the umbilitcal to the 110/240 connection on the side of the house and to the generator.
I started the generator and let it run for 5 minutes to get warmed up.
Inside the house I started a process where I transfered a cirucit, observed the power meter, and checked that I had power in the house. Everything worked perfectly and neither power meter on the tansfer box was showing high use. Waited for the furnace to kick on and still not too much power use. On the same leg of the 240 volt circuit I operated the garage door and did not overload the side. Now I knew both of these cirucits could operate simultaneously. I repeated several scenarios using the Televisions, computers, microware, and even the coffee pot. Everything worked fine. I knew that I could not power up everything or I would overload the generator and likely kick the main breaker. We don't operate the coffe pot at the same time we are using the microware, for example. We don't leave lights on in areas of the house we are not using. We do have several low power night lights in the house.
All in all, a great system that works very well providing you have properly balanced the load and not tried to power up too may things that require a lot of power. Be especially careful of those things that require a higher peak power at startup. These are usually things like a furnace with a motor that needs some grunt power in the beginning but less once it is running. These can be pretty high, 2KW or so, and if they start at the same time they will trip the generators breaker. Be conservative and you will weather a storm without commercial power with ease.
This box comes in several sizes and you should get one that matches the capabilities of your generator.
By the way, I did the work myself but had over-the-shoulder help from a friend that is a licensed electrician.
My signature says Lemon Twist in Manheim Germany.... I came back from Germany in March so all of this was done in the USA.
Installation is very straightforward, and the Reliance video is extremely helpful (as are some other YouTube videos...but be selective there are some really poor ones out there). I'll offer a few recommendations intended to supplement the Reliance video:
1) Spend some quality time planning the circuits you want to connect, confirming the circuit ratings (a 15 amp transfer switch circuit can be used on a 15 or 20 amp branch, but a 20A transfer connection cannot be used on a 15A branch) and balancing the load as Reliance recommends.
2) Do a "trial run" before you start by turning off all house circuits except those you plan to be generator-powered, to see that they provide the coverage you want. You don't want to discover the need for a change after you have cut the wires, or in the middle of a real outage.
3) VERY clearly mark the letters of the transfer switch circuit connections on the breakers you plan to connect...will make installation much easier/more accurate after the main panel cover is removed during installation.
4) The armored cable allows only limited movement, so if you are mounting to a concrete wall, I recommend that that you first anchor a piece of plywood to the wall and then mount the transfer switch to the plywood. so that you can freely/easily position it with wood mounting screws.
5) After mounting the switch and threading the wires into the main panel, divide the wires into 3 bundles, each bound by a twist tie. The bundles are: 1) neutral and ground, 2) circuits to be connected to the left main branch, 3) circuits to be connected to the right main branch. Sort and orient the wires as you do this to avoid a tangle where the.armored cable enters the main load center. This is particularly important if you have a relatively small main load center.
6) The letter markings on the individual wires are NOT as bold/clear an you might hope - triple check that you have the right wires, as you connect them. (separating them into bundles per the prior step provided your first check). In my unit the "B", "E", and "F" wires were quite difficult to distinguish and I discovered a mismatch in the bundles (but before cutting).
7) Confirm your installation after wiring and before connecting your generator by individually switching each breaker you have connected in the main load center between "off" and "on", with the transfer switch set to "line" and then change the transfer switch from "line" to "off" with the main breaker "on" to confirm that each controls the same correct circuit per your installation plan.
Good Luck!

1. Use Wago 221 lever connectors instead of the included wire nuts. Unless you have alot of experience using wire nuts to join solid and stranded wire, they are worth the few bucks to ensure a good connection. I would tape the Wago's as well, just to ensure the levers are not accidentally flipped when shoving all your wires around.
2. Use wire ferrules (google this if you don't know what they are) on your connections you make to your house breakers. When I installed the transfer switch 2 years ago, I ensured the breakers were properly torqued and did a pull test on each one to ensure a good connection. A few weeks ago I needed to remove some circuits in my main panel, and while moving the cable bundles around, 3/10 of the breaker connections came loose. This is really bad. Lose connections means heat and possibly a fire. Likely the fine stranding of the wires eventually bed and caused the connection to loosen off. Using wire ferrules will eliminate this issue. It is definitely worth the few bucks for a ferrule kit and crimper. If you are cheap, tinning the ends might be better than nothing.
All in all, it is a really good product. Just a few extra things you should probably supply to make this a much safer and reliable addition to your house.
A great price for a complete kit that is CUL (and therefore CSA) approved. Meets all building codes in my area and is easy enough to operate that my wife is comfortable doing it.
