Tools List for Installing a Manual Transfer Switch for a Portable Generator:
Drill
Lineman’s pliers
Wire strippers
Shopping List:
Portable gas generator
10-circuit manual transfer switch
Power inlet
10-3 non-metallic wiring
Wire nuts
Steps:
1. Mount the manual transfer switch near the main electric panel.
2. Select up to 10 circuits to be powered by the generator (240 volt circuits require two spots on the transfer switch).
3. Turn off power to the house at the main electric shut off.
4. Remove the cover on the main electric panel (work inside the electric panel is only recommended for licensed electricians).
5. Locate an available knockout hole on the electric panel and remove the plug. Attach the armored cable from the transfer switch to the electric panel.
6. Connect the ground and neutral wires from the transfer switch to the appropriate bus bars on the main panel.
7. Locate the first circuit to be powered by the generator and remove the power wire on the existing circuit breaker. Replace that wire with the red wire from the transfer switch marked “A.” Splice the black wire marked “A” from the transfer switch to the removed power wire using a wire nut. Repeat this process for all 10 circuits, ensuring the red and black wires from the transfer switch are a matched pair.
8. Use 10-3 non-metallic wiring to connect the transfer switch to a power inlet outside.
9. Use the provided generator cord to connect the power inlet to the generator (or make your own cable if a longer one is desired using bulk wire and connectors).
10. Ensure the generator has unleaded fuel and oil inside, then start the generator.
11. To test the wiring connections, flip the switches on the transfer switch from “Line” to “Gen.” The generator should power the selected circuits.

I have a permanently installed 8 kW genset, propane fuel from 2 100 gal cylinders, and an automatic transfer switch. It's saved the day a number of times since utilities were "deregulated". If you're going with a portable genset there are three things I'd recommend: (1) Document every circuit breaker at your service entrance. Make sure you have a list of every load that every circuit breaker serves. With a 200 A service, you can't power up every circuit with a 7 or 8 kW generator. You can buy a kit to help you do that at Lowe's, Home Depot, or Harbor Freight for $20-25 (or so). (2) Get a "dual fuel" generator - gas or propane, for example. Long term storage of a 20 or 30 # propane tank is much safer than long term storage of 5, 10, or 15 gallons of gasoline in a can in your garage or pole barn. (3) If you go with gas, use ONLY non-ethanol (and do this religiously) - like in your lawn mower or boat.

[@HK-qj4im]

Great advice. All small engines.. no ethanol. Only way it would be ok is if you are running your generator non stop. You can not store Ethanol blended fuel long term....unless you like cleaning fuel systems.

[@nodak81]

I've been using regular pump gas in all the equipment I've accumulated since I bought my house 13 years ago. It keeps for up to two years if you stabilize it properly. I'm up to about 20 pieces of equipment and they all still have the original carbs, etc. Haven't had a single fuel issue in anything. The real key is to always shut off the fuel and run the carburetor dry, if you do the equipment will be fine. Buying ethanol-free is expensive, difficult and totally unnecessary.

Another nice thing about these manual transfer switches is that you leave one circuit not desired on genset power to alert you when line power is back with a radio and/or light plugged in. I keep my main HVAC breaker off until I know power from the grid has stabilized anyway and this is the way to go for alerting you safely.

[@HomesteadEngineering]

I think what you show in the video is a really good setup and probably the best way to go for most people. For those thinking of installing a whole house 20kW backup system, I would like to offer an alternative idea to consider. For the same/similar price, you could install a 4kW solar power system with an 8kW generator and battery backup. That way, instead of just sitting there waiting for an emergency, your "solar backup" system is helping to power your home all the time saving you money. When you run a 20kW backup generator, you end up wasting most of that power most of the time and it burns a lot of fuel. With a battery backup, you run the 8kW system, burn less fuel and use all the power to charge the batteries for about 2 hours and then shut if off for about 24 hrs while you run off the battery. Anyway, that's how I do it and it works great!

Some people unplug their dryer or electric range and backfeed the house through the plug. It's very unsafe since doing that can send power back through the mains and exposes high voltage on the male prongs of a power cord.

[@kspdt]

Thanks for the info. Question - why not just put a transfer box in the main line ahead of the breaker box? Run the generator power into the transfer box that runs into the main line breaker box. Then turn the house breakers off or on depending on what circuits you want to use? That way you have access to all the circuits, albeit you wont be able to use all at once.

A cheaper option would be an interlock kit. This option also allows you to choose any circuit you want. The transfer switch limits you to 8 or 10 circuits...depending on the transfer switch you purchase. Search KZbin for videos about interlock kits.

Just completed the break-in period and so far the unit is operating perfectly kzbin.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y . I was amazed by just how quiet this little guy is. I kept having to walk down the driveway to the generator to make sure it was still running. In fact, the most annoying noise coming from the set-up is a high-pitched chirping coming from the pressure regulator on the propane line. I suppose it's possible my other propane-powered generator's pressure regulator is making the same noise, but the generator itself is so loud I've never noticed it. Build quality so far is excellent. My only nit is the service panel is a little tricky to remove. I feel like I might break off one of the plastic tabs when bending it back. I probably just need to work out the technique, so will not hold it against Champion.Next week I intend to fully load the unit to charge a large battery pack and will update this review if there's any problem (3000W continuous load vs a rated 3100W capacity while using propane). Absent any trouble there, I'm 100% pleased with this purchase.

The reason for this is that a home can become negatively pressured - you turn on two bath vents, a vent hood or you have a water heater or furnace which draws its combustion air from inside the home and then vents it outside the home. In all of these cases, there will be a chance for ANY opening in the home to suddenly become an air inlet.

[@mowcowbell]

An option for this homeowner would have been to purchase a dual fuel generator. This type of generator can run on gasoline or propane. Gasoline will go bad over time, even with fuel stabilizers. Propane on the other hand will never go bad, and will not gum up the carburetor of the generator. During a widespread outage, gasoline might be hard to find, especially if fuel stations have no power to run their gas pumps.

[@USAads2023]

Mowcowbell petrol is over 50 million years old. gasoline never goes bad, you get water in the gas container do to condensation and moisture created by H in gas and O in air. Read a book, it will not hurt you

[@hawaiianking63]

While using normal gas it will run at a higher kw, while using propane it will run at a lower kw. So depending on what your house/situation requires, dual fuel may not be the best way to go.

[@phillijp]

Think before you speak, there isn't a single drop of gasoline that's anywhere near 50 million years old and gas most definitely goes bad especially if it is blended with ethanol.

[@USAads2023]

phillijp question, gasoline comes from? Petroleum. Propane also comes from petroleum. See they exist since they were captured in the bodies of prehistoric monsters and plants. Read a book, it will help. What makes gasoline go bad is condensation produces water and also H when mixed with O it makes? Water

[@phillijp]

Crude oil is millions of years old. Gasoline which is produced in a refinery from crude oil is not anywhere near as old as you assert. The process by which this occurs is called fractional distillation. Also gas is lighter than water, put them in a container, mix them for as long as you like and once you stop they will separate through a process known as phase separation. Condensation is the process of a gas turning back into a liquid. Condensation does not produce water nor does it produce hydrogen. Perhaps you should be the one reading books.

Step by step instructional videos are available on the KZbin channel for Reliance Controls, and the connection of a 240v circuit is addressed.

@@miked6335 Yes, this is also bad. The same thing occurs when the generator runs out of fuel. Most owner manuals state to not let your generator run out of fuel while under load (UL).

The problem with most of these KZbin videos that talks about transfer switches is that they are not telling people that they need to “pair the type of transfer switch to the type of portable generator” they plan/want to used. The thing to know/remember is your house service panel is neutral to ground bonded (N-G bonded) which means that the neutral and the ground are connected and should not be N-G bonded AGAIN throughout your electrical system. With that is mind, you can get transfer switches that either transfer the neutral or doesn't. Also, with portable generators, you can get them either “Neutral Bonded to Frame" which means the portable generator's neutral is connected/bonded to the ground or “Floating Neutral” where the neutral and ground are not connected/ bonded. Most but not all portable generators are Neutral Bonded to Frame. So if you decide to get a transfer switch that doesn't transfer the neutral then you need to get a portable generator that is Floating Neutral so that your electrical system is not N-G bonded at two location/places. If you get a transfer switch that transfer the neutral then you need to get a portable generator that is Neutral Bonded to Frame so that your electrical system is N-G bonded when the transfer switch is switched on. Most portable generators are Neutral Bonded at the Frame to meet code when they are used as a stand alone (Separate Derive System). If you plan to use the portable generator just for backing up to your electrical system with a transfer switch then get a Floating Neutral portable generator with a transfer switch that DOESN’T transfer the neutral. But if you want to use the portable generator as a backup AND to use it outside your electrical system, get a Neutral Bonded to Frame portable generator with a transfer switch that transfer the neutral so you don’t get N-G bond at two locations/ places. Another issue not discussed is Grounding the portable generator. If you are using a Floating Neutral portable generator with a transfer switch that DOESN'T transfer neutral, you are not required to ground as your portable generator is using your electrical system's ground. If you are using a Neutral Bonded to Frame portable generator with a transfer switch that transfer neutral then it is a Separate Derived System and as such, the portable generator needs to be grounded.

[@denali9449]

@@denisrhodes54 That;s why real electricians use term like 'grounded' and 'grounding' conductors. Helps eliminate any confusion. Additionally, in this situation, the service panel is the one outside where the main breaker is located and where your grounded conductor would attach.Four wires would run from here into the house to the panel where they were working which is technically a sub-panel so the 'grounded and grounding' conductors are isolated.

Can you find an electrician as good as this guy??😏

[@Redgascan]

Great video. I have a question. After the power comes back on, does the transfer switch stop the flow of electricity from the generator before you can get outside to turn off the generator? I heard you say the switch lives in the off position, is that where it returns or do I need to turn the switches back to off after turning off the generator?

[@nicknamednickify]

I was wondering the same thing. The term manual transfer switch makes it sound like you have to do it yourself. Auto transfer switch would be a better thing if it would turn that off for you. What happens if your generator is running and the power comes back on? Not only that, but how do you know your power is back on from the utility if you're using the lights and other circuits with the generator?

[@RelianceControls]

The individual switches on the transfer switches are between the breakers and the loads (appliances, outlets, lighting, etc). When the generator is connected and the switches are moved to the GEN position, each switch independently disconnects the only feed to it from the house breaker panel. It's basically 10 transfer switches in one cabinet. If the main power is on and the generator is on and connected, it's perfectly safe to have some of the circuits in the LINE position (main power) and some of the circuits in the GEN position (generator power). Each circuit is isolated by the way the toggle switches are between the breakers in the house panel and the breakers in the transfer switch. The center OFF position is the "break" position so that when moving a switch up and down there is always a disconnect so the power sources always remain isolated. Normally the switches are in the LINE position, if there is an outage then a generator is connected and the switches are moved to the GEN positions as needed by the person attending to the system. It is usually obvious to some extent when the main power returns, because everything not being fed by or connected to the generator will instantly turn back on. Generally there is something somewhere that will indicate to someone that the main power has returned.

[@RelianceControls]

Hello, if you have a renewable energy (solar panel) system and an inverter, everything depends on the type of the inverter. If it's a "grid-tie" inverter, which syncs with the utility power and supplies power to the entire system at the same time as the utility, it cannot be used during an outage because it has to detect a utility outage and shut itself down (or it would send power back down the utility line). Grid-tie systems usually don't utilize battery bank storage and will sometimes use microinverters built-into the solar panels. If your inverter is NOT a grid-tie and does use a battery bank, it would use either a small automatic switch, or it could use a manual transfer switch like this one. All depends on the type of inverter and how it's integrated or planned to be integrated into the electrical system. With a "NON" grid-tie, you can use it at any time by picking any of the circuits on this type of switch, moving them to GEN and running them off the inverter power at the SAME time the utility feeds everything else. This is perfectly safe and the only concern is that you don't monitor the battery power and the available power from the battery bank gets too low, the inverter will crash and any circuits fed by it will stop working until you realize this and flip the switches back to LINE, reset the inverter, and when there is enough energy once again in the batteries you can resume using it to power some (or all) of the circuits on the transfer switch.

[@RelianceControls]

No you cannot, the "class" of the inverter is critical and determines if it's possible to utilize this switch with an inverter rather than a separate portable generator. It won't work ONLY if you have a grid-tie inverter, because the inverter won't work when the main power fails unless a very sophisticated automatic switch AND another inverter AND another automatic switch are all incorporated. It's required by law that a grid-tie inverter has an RSD feature, which is Rapid Shut Down. It must detect the utility power failing and shut itself down until it detects the return of the utility. It can do this in a variety of ways based on who made the inverter. However, any inverter EXCEPT a grid-tie inverter can potentially be used with this transfer switch. There are some unique attributes on some (non-grid-tie) inverters in regards to their internal neutral/ground relationship, which could cause issues especially if there is GFCI built into the inverters and their neutral is bonded to their grounded (metal/conductive) parts. Inverters comes in two main classes - non grid-tie and Grid-tie, and this makes ALL the difference. The class of the inverter is critical because the two types of inverters are very, very different, and if you have a grid-tie you cannot use it when the power fails without an extremely expensive setup of 2 automatic switches and a 2nd inverter that is not a grid-tie.

So, this seems to be a big debate on the internet. We have a Transfer Switch, which is safer and works for what we would need in a power outage. Here are some Pros and Cons of each option. Interlock Switch Pros: 1) Cost less. (Switch ($70), watts meter ($90) and inlet box ($60) Total $220) 2) Can choose any circuits to power on/off. 3) NEC compliant and UL listed. 4) DIY project. Cons: 1) Main breaker has to be off. 2) All individual breakers need to be turned off before switching over to generator power. 3) Potential to back feed the main power lines. 4) Harder to balance both legs of generator. 5) Have to modify main control panel box. 6) Have to install a double poll 30 or 50 AMP breaker. 7) Might have to pay an electrician to install. Transfer Switch Pros: 1) Cost more, but can buy a kit which includes everything you need to install. (Transfer switch prewired, conduit, power intel box and power cord $300-$440) 2) Easier to manage power load. 3) Easier to balance leg loads. 4) Some switches come with a standard circuit breaker for each circuit. 5) Each circuit is isolated from utility or generator power. 6) Impossible to back feed either utility or generator power. 7) When power is restored, you'll know it by whatever circuits not included in the transfer switch. 8) No need to switch off/on any breakers in the main control panel when switching between "Gen" and "Utility" power. 9) NEC compliant and UL listed. 10) Can switch to generator power, while utility power is still powering your house. 11) Can have 10 individual circuits or 5 double poll circuits. (Only one can be a 30amp double poll) 12) Idiot proof. 13) DIY project, but more involved. 14) Comes with a watts meter. Cons: 1) Can be costly 2) Limited to the same 10 circuits you choose. 3) Might have to pay an electrician to install.

People are wondering why he doesn't just have a nice automatic standby diesel or natural gas generator installed. That's a good question. Here's mine: Have you ever had to depend on true professional prime generators? Because I work at a radio network and between our studios and transmitter sites we have 10 beefy primary professional grade 60-120 KW generators with automatic transfer switches and all the bells and whistles. And let me tell you something: They are a constant pain. An absolute constant pain. We have to keep after them every month, changing belts and filters, batteries, and so forth. Whenever there's an extended power outage, one or two of them will always fail. Sometimes they won't start. Sometimes they burn a winding. Or the transfer switch freezes. Or the $500 deep cycle battery quits years ahead of time. These are professional generators, brands like CAT and Cummins, meant for continuous off grid use, very well sized for their loads (not exceeding 50%). Not your wimpy Generac home standby system. Based on more than a decade of experience with these generators, plus all the horror stories from peers one accumulates, I'd never shell out a load of money for an automatic home system. Better to have a nice setup like this in place so I can connect a generator of my own at any time. It costs a lot less to drop into Costco and buy a $700 portable generator and toss it when it breaks, than it is to get a $10,000 home system installed that fails me when there's no technician to come out and look at it. You can say that it "should" not be this way, but let me ask you something: If a radio network with over a million dollar a year budget on maintenance with a licensed diesel mechanic, a licensed electrician, and engineers ON STAFF has issues with true professional diesel generators, what are your chances with a cheap Home Depot one installed by some subcontractor?

[@joea1433]

To Jose Quiñones - You make good points, as an industrial/commercial electrician who has installed generators up to 13kv, if something can go wrong it will even though it should not. Million dollar maintenance contract! For the homeowner, most outages are not long and if you have city water and natural/propane gas heating, you don't need much generation. With a well pump, having water makes all the difference in the world so money spent is worth it, especially with kids. The generac auto transfer schemes definitely make sense for many people's combination of circumstances though. A very good, simple scheme is if the local power utility allows the transfer switch to be part of the meter socket and a simple cord run between the generator and the metersocket. Almost child proof!

[@mowcowbell]

Jose, very good argument against a whole home generator. I priced out a whole home Generac 22kw system for my home, and the estimate was over $9000 installed. For less than $2000, I bought a 10 circuit manual transfer switch, paid for a professional to install it, and bought a 7.5kw dual fuel Champion generator ($799.99). With this setup, I can run all my lights, TV, window A/C unit, microwave, garage door opener, etc. Pros? I can use gasoline or propane. Cons? I can't run 220v appliances like an oven, central A/C, or a clothes dryer. I do have to deal with the minor inconvenience of pulling the generator out of the garage and connect the 30amp cord to the panel outside. For that 5 minutes of work each time the power goes out, I saved $7000.

[@NebukedNezzer]

As the senior tech at a public safety radio shop. I chose a big 400 gallon propane keep full serviced tank(half or better) brought liquid propane into the generator building to the gasifier that uses engine coolant. the engine has block heater. nice 454 chevy v8 on propane gave reliable back up power for the 20 years I worked there. All I did was have the generator service company out once a year to do check over and maintenance. much better than diesel those gave lots more trouble. its back up so the extra cost of propane is not a big deal at all. the propane service company let us use their tank as long as we got the fuel from them so that was a good deal. now that I am retired I keep a 2000 watt portable gas generator in my garage with the gas empty. If I need to use it like to run the furnace or refrigerator. I take it outside and put some fresh gas in it. I am not going to tell how I hook it up. but its easy and easy to put back to normal when power is restored. One thing to remember, besides how not to hurt yourself. be sure that what ever you rig up does not feed power back into the electrical grid and kill some power company guy trying to make repairs.

LOL .... Our Generac 22kW system has been installed a little over 10 years and works perfectly every time the power goes out including one time for two weeks! I'm betting your cheap-ass radio station didn't do routine maintenance.

We own a standby generator, which not only exercises itself for twenty minutes weekly, keeps our basement sumps (and a lot of other things) going if we're not home through an automatic transfer switch, and has twice the power generation of a portable unit.

Ampacity Electric We paid $4500 for our Generac automatic system, not $12,000 (5 years ago). Installation not included in that price, but then again it's not in your quote on the portable unit, either. 😊. I bet we'll get half of that back in the home resale. Again, it basically powers our entire house, garage doors and everything (unlike the homeowner in this video that had to select ten devices). Frankly, I know three others who own portable units like in this video, and they all suffer with them not working in emergencies. It's not like the electrician in this video makes it sound when he says "just put it in your garage". Engines need to be run routinely, even treated gasoline goes bad, spark plugs and carburetors get corroded and clogged, and few owners routinely maintain their portable generators, let alone fumble around in the dark starting them cold. Just another view of factors to consider as one makes their own decision. Everyone has their own needs. Many make do with just a Honda i2000 small jobber.

[@ZeoCyberG]

Well, it is true that the reason for this setup is because the area in question is prone to disruption from earthquakes... However, there are rugged, with vibration isolators, solutions that could still work... Just maybe not in the home owner's budget range... I'd personally pay the extra expense and go with a hybrid solution with battery bank, inverter, and the generator... Reminds me of a story I read once back when we had that big North East regional blackout back in 2003... A engineer had a hybrid car and hooked it up to power his home during the blackout... Basically powering the house off the batteries and setting up the engine to start and recharge the batteries when they got low and then shut off until the batteries got low again... On one tank of gas he kept everything running all week... A good generator can adjust its power output and fuel consumption but it's hard to beat a hybrid system for efficiency and I think that makes it worth the extra costs... While still being cheaper than going with solar, etc. and even if the generator needs to be stored away when not in use, the UPS means I'd have plenty of time to set it up and short outages wouldn't need the generator at all...

That cord/receptacle would supply 30 amps on each phase (red/black). The other thing most people don't often realize is that keeping the genset fueled for a long outage can become a problem with fuel availability especially after a major catastrophic event. Propane might be a good source. It "stores" for long periods, pretty safe in its containers, multiple containers could be stored. It was always "illegal" (National Electric Code) to splice inside a panel. Has that rule gone away??

[@RelianceControls]

Hello, yes it's imperative to learn a little bit about power usages of appliances when operating them with a generator. Splices have not always been illegal, there have been exceptions for splices for a very long time. As long as the fill factor of the area inside the panel isn't too high, and the splices are purposeful rather than being used as a feed-through such as a junction box, they are acceptable.

So, what you want to do is, once the power is restored, go turn off your generator FIRST. Then, come back into the house, and flip those breakers in the new box all back to "line". So only if you would have the generator still running when the power comes back on, and then you go down there and flip those breakers to "line", would you now be feeding generator power back into the lines. That's how I understand it. Anyone else?

Great video. Very good job explaining how it all works!

Came here after Texas' artic storm blew down here. Great video. Would want to go extra step to tie in natural gas line to generator.

What I'd really like is for electricians who initially install panels in new houses to have to take a course in writing legibly.

[@jmdelapp]

I they should have to take a course in filling out panel schedules. I come across blank schedules all the time.

[@ohger1]

Not possible. Most electricians are med-school drop outs..

Without electricians you wouldn’t have WiFi to make dumbass comments.

@@dallas5374 QUESTION: Why dont he ground the generator frame to earth?? Is it a FLOATING NEUTRAL generator, or a BONDED NEUTRAL generator? doesnt that matter?

[@KianaShalix]

Sorry if this was explained but when your power goes out do you shut off the main power to run the generator cause my concern is if your generator is running and the power starts coming back on what happens now because they are both providing electricity?

[@fordhamdonnington2738]

03:30 the manual transfer switch allows you to safely transfer the power from the commercial power ( which won't be running anyways because it's out because of the storm). When the power is restored you'll see the non- essential lights wired in the regular box come.back on. Watch it again
