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.

This transfer switch automatically changes from inverter to shore power when you hook up at the campground. Protects your electrical system from AC power backfeed.


Great product at great price. Original transfer switch was having problems, and no longer in production.


Order showed up a little early. Love that. Haven’t installed it yet but looking forward to it and expecting zero issues.


Solid metal Box With easy diagram to follow for hooking up your connections. It can easily handle 6/3 wire.


Simple, effective. Did what I needed it. Takes a few seconds to transfer over, but expected.


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

Great product

Working good had no issues


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.


Good product. No worries.


Seems to be working just as anticipated.

  • Go Power Automatic Transfer Switch Supporting Dual 2000 Watt Inverters
    I contacted our Go-Power Rep for this question to ensure we provided you best possible response about the Go Power Automatic Transfer Switch, # 34270278. After explaining your question they stated that conceptually this should work the way you are wanting, they however have not tested this configuration to be able to verify.

  • Go Power Automatic Transfer Switch Generator/Shore Power
    Not knowing how your current components are wired it is difficult for me to state that with confidence. However, detailed instructions are provided showing the proper integration of this ATS into your system. The Go Power Automatic Transfer Switch, # 34270278, is intended to automatically change from operating your systems off the inverter shifting to shore power when you hook up at the campground. It will protect your electrical system from AC power back feed. If properly wired, follow...

  • 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 the Go Power Automatic Transfer Switch Support Switching Between 2 Power Sources
    The Go Power Automatic Transfer Switch # 34270278 provides automatic power switching between two or three separate 120/240 volt AC input sources, including power cords, onboard generators, onboard inverters, or all three. The ATS will sense the presence of available power supplies and automatically select the proper one. I have also attached the owners manual for the Go Power Automatic Transfer Switch # 34270278 which goes over its capabilities more in depth.

  • 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.

  • 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...

  • 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!

  • 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.

  • 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.

  • 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.

  • Advantages to Using Go Power Automatic Transfer Switch # 34270278
    The advantage or pro, of having a converter/charger in one unit, such as the Progressive Dynamics Mighty Mini Converter/Smart Charger, # PD4045KA is having it all in one package; you know that all subcomponents are matched to function with each other. The way the Go Power Inverter, # 34278156 that you linked to works is to be connected to your RV's AC battery bank providing 12 Volt DC output. That battery bank is charged from the AC input of the shore power connection, or solar, or generator....

  • 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...

  • 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 - for example the Jensen LED RV TV - 40" Screen # JTV4015DC only uses 70 watts - 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...
