go power pre-wired 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. 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.

Quick, Easy Wiring

transfer switch wiring

The transfer switch includes an inverter output plug and converter charger input receptacle that help speed up installation time. The converter input is only active when shore power is available, ensuring the converter does not use battery power for charging.

Automatic Transfer Switch Installation

There are several wiring configuration options, depending on the electrical application inside your RV. With this quick connect version, you can easily plug into the inverter and converter charger with no wiring required. However, it does need to be wired to the AC panel and shore power input.

cord knockouts

The plastic case also has cord knockouts for other connections.

Wiring Example

transfer wiring example

In this wiring example, the transfer switch selects between the inverter and shore power (or an on-board generator). The converter is also capable of charging the batteries while shore power is active. Lastly, the AC panel is powered by either the inverter or shore power, depending on which is currently providing power at the time.

Video Transcript for Go Power RV Inverters 342GPTS Review

Speaker 1: Today, we're taking a look at a Go Power 30 amp, pre-wired transfer switch. This transfer switch provides automatic power switching between two separate 120 volt AC input sources. It is pre-wired and circuit protected, and it's designed with special features to really help simplify and speed up the installation. So, I've popped the lid off here, give you a look internally. You can see that's all pre-wired. It includes a cable with a builtin plug to connect to inverter output, and a receptacle that powers your converter, only when shore power is available.Now, I do want to point out that the ports, like the plug right here, they're labeled so this one says, "charger," this one over here says, "inverter," and the one on here says, "shore power." So, they're labeled indicating where they go, what they connect to.

An automatic transfer switch is usually installed to allow both your inverter and shore power to alternatively feed the circuits and prevent AC back feed. Now, this automatically connects shore power when available to your breaker panel, and when unplugged from power, it then connects your inverter output to power your circuits.Now, a transfer switch is a great option when it comes to powering the central distribution panel, which is where all the RV circuit breakers are located when power is needed, when you're not plugged in to a camp ground pedestal or shore power. The plastic enclosure is strong and durable, protects everything inside. Now, the box itself, I took measurements, at the widest points, which would actually be here at the top, 'cause you'll notice that the box kind of tapers out. So, edge to edge going this direction is about 8-5/8," edge to edge this direction is about 7-3/8," and then the overall height is about 4-1/8".The mount holes on the unit, like these right here, these are separated on center, going this direction by 8-13/16," and then going this direction, the mount holes are separated on center by 5-7/8".

That's gonna do it for today's look at the Go Power 30 amp, pre-wired transfer switch.

  • 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.
