go power 50 amp automatic transfer switch

This transfer switch has been pre-wired to automatically change the primary source of AC current from inverter to shore power to conserve battery life. The switch includes (2) 50-amp legs, which allow you to use up to 100 amps on a shore power service. The legs are rated at 120V each and allow for 240V service. To prevent electrical interruptions, the time delay circuit board allows the alternate power source to stabilize before a transfer occurs. Additionally, since the switch only accepts one active source, it protects your electrical system from dangerous backfeed that can damage your equipment.

The metal case also has cord knockouts for connections.


Automatic Transfer Switch Installation

internal view

There are several wiring configuration options, depending on the electrical application inside your RV. These include installation between shore power and an on-board generator, an inverter and an alternating source, or even a hybrid system using another transfer switch for designated circuits.

I converted a system where I had to plug my shore line into a separate socket for the generator. This meant I was always wrestling with the 20' shore line in it's storage compartment. Adding this switch allows me to have a totally separate shore line that I can store much easier. Switching from shore power to generator is now a breeze

New switch has held up to the rest of time. Not having to plug my shore line into a socket to use the generator has been a true convenience. I can now easily shift to a lighter gauge shore line depending on power needs. If I dont need my AC I can get away with a simple and light weight 12 gauge line.

I had a transfer switch fail in my 2005 Alpine coach. I replaced it with this unit. Was essentially a direct replacement. This unit was little smaller and had to make different ground legs, otherwise seamless install. If you read the reviews about buzzing and what not, just skip them. No noise no heat nothing but perfect transfer of power from gen to shore.

Each time I have ordered from etrailer the product was as advertised, arrived in a timely manner and worked perfectly.

Everything went smooth and Ashley was a great. She explained how much shipping was and got it out Next Day Air. Everything matched up at the end of the day with what she told me.

One important thing I learned from this adventure is that 30 Amp outlets for dryers and electric ranges are not wired like 30 Amp outlets for RVs. The RV outlet is wired as single phase 120 volt service while 30 Amp outlets for dryers and ranges are wired for dual phase 208 Volt service. Sadly, I only learned about the different wiring scheme after I had fried my RVs originally installed ATS and the new ATS I received from etrailer. It took a lot of troubleshooting and testing, along with some intense internet surfing, for me to learn why I had thoroughly destroyed two ATSs. So, for future purchasers of RV ATSs I recommend validating the wiring of the service outlet they plan to use. It was a $[XX] lesson for me, and that is just the cost for parts.

Do you have a question about this RV Transfer Switch?
  • How to Determine Correct Inverter for TV and Coffee Machine
    I can definitely help you determine the correct inverter for your TV and coffee machine. To figure out the correct inverter, you simply need to know the amount of watts your TV and coffee machine use. While TVs don't generally consume much wattage, coffee machines use up quite a bit of energy, often over 1,000 watts. So I think you hit the nail on the head with the 2,000 watt Go Power Industrial Pure Sine Wave Inverter # 34278156. This would be the best option for your needs, and for...

  • How Does Go Power Automatic Transfer Switch # 34270278 Connect to Shore Power and Inverter
    The Go Power Automatic Transfer Switch # 34270278 that you are interested in was designed to automatically switch power sources between an inverter or an AC power source. You'd want to run the inverter you have now to this as well as the power source wiring from shore power and this would automatically take care of your AC power needs/switching. Basically your battery would connect to the inverter, the inverter to the # 34270278 and then the # 34270278 to your fuse panel. This does not...

  • Does Go Power Automatic Transfer Switch Have Switch to Remove Generator Delay
    Hi Doug; I reached out to Go Power and the # 34270278 does not have a toggle to remove the delay for a generator. As it is, there is a preprogrammed 20-30 second delay so the generator has a brief warm-up period. They did say you can work around this by adding a shunt jumper to the timing board. The silk screen on the transfer switch has writing on it to indicate where to put the jumper. What kind of trailer do you have?

  • How to Power a Winch on a Cargo Trailer
    Hey Tim, that's a nice trailer! Another way to power the winch on your 2017 Cargo Mate would be to have a large deep cell battery installed on the trailer that will power the winch and then use the 12 volt accessory circuit from the 7-way on your truck to put a maintenance charge on the battery. You could then run lights off of the same battery. Or and this is my recommendation, if you have a winch with up to a 16.5k capacity you could get the Trailer and Vehicle Electric Winch Wiring...

  • Can Solar Generator Connect to Go Power Automatic Transfer Switch
    Hey Prabha! Yes, you can use your solar generator with the Go Power Automatic Transfer Switch # 34270278. It will work the same way it does with an inverter, and prioritize shore power over your generator. Keep in mind, you want to make sure your particular model has built-in inverter/transfer capability, and the AC output is compatible with the transfer switch. I would read through the manual, or ask the manufacturer, to make sure it is capable of this. What kind of solar generator...

  • Inverter for 1995 Gulfstream Sun Voyager
    Hi Robert; to find the right inverter you will need to evaluate your power needs. Also, the Progressive Dynamics 1000 Watt Inverter w/ Transfer Switch # PD94FR you were looking at wouldn't work since the transfer switch is only rated for 20A. For something similar you could use the Go Power Industrial Pure Sine Wave Inverter - 1,000 Watt # 34279948 or 1,500 Watt # 34279951 and then add in a transfer switch like # 34270278 separately.

  • Difference Between Go Power and Furrion RV Transfer Switches
    Hey Rob, the big differences between the two transfer switch is that the Go Power part # 34270278 is made in the USA and has a metal case whereas the Furrion part # F50ATS is not made in the US and has a plastic case. This is why it costs less. Generally speaking the LiFEPo batteries do not require venting but you still want to check with the battery manufacturer to be certain.

  • How Can I Power My Camper From a Generator With the Hard Wired Watchdog Surge Protector?
    As I am not sure of your specific camper there are a couple options to check out. First the Hughes Autoformers Ground Neutral Bonded Plug for Generators # HU33FR is designed to allow you to plug into your generator without causing the Power Watchdog Surge Protector # HU27FR to fault. The plug inserts into an unused outlet on your generator to create a neutral to ground bond. If your generator is an onboard unit that is hardwired to the camper you will want to install the surge protector...

  • Automatic Transfer Switch Recommendation for a 5,500 Watt Onan Generator
    Since the Furrion Automatic Transfer Switch # F50ATS is only rated for 3,750 watts I recommend going with the Go Power Automatic Transfer Switch # 34270278 instead. I reached out and confirmed with my contact at Go Power that this transfer switch will work with your 5,500 watt Onan generator. Attached are some review videos for you to check out!

  • Is A Transfer Switch Necessary On an RV?
    Yes you are going to need a transfer switch if you plan on using more than one AC power source on your RV. For instance, if you're plugged into shore power and would also like to use a generator, then you'd want to use the Go Power Automatic Transfer Switch # 34270278.

  • Recommended Made in USA 50 Amp Automatic Transfer Switch for RV
    Yes, the Progressive Dynamics Transfer Switch part # PD52 has an automatic design with 50 amp rating and it's made right here in the USA. We also offer the Go Power Automatic Transfer Switch part # 34270278 which is an automatic switch with 50 amp rating made here in the USA. They are both great options, the Go Power is slightly smaller but I would go with whichever is more cost effective at the time.

  • Will the Go Power 50 Amp Automatic Transfer Switch Work w/ a 30 Watt Generator?
    Yes, the Go Power Automatic Transfer Switch item # 34270278 will work with your 30 watt generator when you are not hooked up to shore power. Since you're running an invertor with solar you will need two of the item # 34270278. You can't run three power sources with just one. I have linked a diagram below that will help you get set up.

  • Will the Go Power 50 Amp Automatic Transfer Switch Work with DuroMax 13,000 Watt Portable Generator
    I spoke with Go Power and they did inform me that you could use the Go Power Automatic Transfer Switch part # 34270278 with the DuroMax 13,000 Watt Dual Fuel Portable Generator. It really doesn't matter which generator you use, the transfer switch is setup for two power sources.

  • Troubleshooting Low Power from Shore to Transfer Switch
    It sounds like you have a short in your Power Cord wiring as there isn't anything between the power cord and the Go Power Transfer Switch # 34270278 as they are directly wired. I've attached a video of the Go Power Transfer Switch - Quick Connect - 30 Amp # 342GPTS which shows these connections. If you don't use and in-line circuit breaker like # CAM55306 then there has to be an issue with the wiring or the ground on the transfer switch itself.

  • How To Wire 240v Generator Power And 120v Shore Power To A Go Power Automatic Transfer Switch
    The Go Power Automatic Transfer Switch # 34270278 lists in the instruction manual that the generator will be dominant power source so you would just need to wire the generator 240v to the generator input side and shore power 120v to the shore line input side. I've copied the wiring instructions below: 1. Connect the powercord neutral to the powercord lug labeled NEUTRAL WHT. 2. Connect powercord hot 1 and hot 2 to powercord lugs HOT 1 BLK and HOT 2 RED. 3. Connect the generator neutral(s)...

  • Can 50 Amp Transfer Switch for RV be Wired for 30 Amps
    There isn't a way to wire our 50 amp transfer switches to work with 30 amp so your best solution would be a 30 amp switch like the Furrion part # F30ATS.

  • Why is Transfer Switch Needed with RV that Uses Shore Power and Generator
    The transfer switch is needed if you plan to use more than one AC power source for your camper. So if you use shore power from a camp site and also want to be able to use a generator you need the transfer switch like the part # 34270278. With DC power you can run more than one power source to a circuit and there's no issue but with AC power you can't run two power sources to same circuit at same time which is why the transfer switch is needed.

  • Does Go Power Industrial Pure Sine Wave Inverter # 34278156 Have Transfer Switch
    What you are describing is a transfer switch that would allow the # 34278156 to be bypassed when shore power is connected. This unit does not have a transfer switch built in and it would need to be added on with the # 34270278 or you could go with a setup that has the transfer switch built in like the part # PD4045KA.

  • Will Go Power Automatic Transfer Switch Auto Start/Stop the Generator
    The Go Power Automatic Transfer Switch part # 34270278 won't start or stop the generator, it simply stops the transfer of power to the main source when shore power is detected. The term automatic refers to the automated stop of power i.e. no manual switch, not ignition to the generator. The generator would need to be started and tuned off manually.
