Furrion's transfer switch is wired to automatically change the primary source of AC current from shore power or an inverter to a generator when available. So, in the case that you unexpectedly lose shore power, the switch will automatically begin to run power to your RV's appliances from your generator.

The switch between power sources is seamless to the point that you won't even notice the difference in power being sent to your appliances and electronics. The 50-amp single pole switch provides 120V or 250V AC. To prevent electrical interruptions or damage to the system, the time delay function utilizes a 20-30 second window to switch between power sources. This protects against dangerous backfeed, and keeps the voltage from each power source from being active at the same time.

The time delay function features a bypass switch for inverter power. Since an inverter doesn't need time to warm up like a generator does, you can bypass the time delay for instant transfer from shore power to inverter power.

The plastic case has 10 punch-out holes which allow you to arrange the cables and wiring in whatever way is best for your setup. The included user manual lays out 3 typical setups for you.

The switch wires to your shore power input and generator or inverter input. Both inputs are wired to the AC panel.

shipping was a bit slow in receiving but got all wired up in my RV this morning, everything fit perfectly, hopefully this Furrion replacement lasts longer than the original one! 691806

Orginal one the shore power side got fused open. Unable to charge or plug in. Weekend order. Payed for fast shipping and got just that. 876456

Worked perfect. 782969

- F50ATS

I bought two of these when my brother and cousin upgraded my RV electrical system from 30 to 50 amp. One for the generator and one for the inverter. They “dummy proofed “ it by using two. It’s been over a year and no problems. ETrailer delivered quickly and sent everything I needed to get the job done right (except for the brother and cousin who were willing to do the installations! 733776

- F50ATS

Exactly same as unit as originally installed one that got “fried” by power surge. Hopefully I will be smart enough to keep surge protector on in future so won’t have same thing again. 678478

Perfect fit for replacing unit that had gotten “fried” during electrical storm. Function perfectly. No complaints at all.

Ask the Experts about this Furrion RV Transfer Switch

  • Can I Use 50 Amp Transfer Switch With 30 Amp RV Setup
    It is possible to use a 50 Amp transfer switch with a 30 amp setup since you plan on upgrading in the future however, the Furrion Transfer 50 Amp Switch is made for 50 Amp setups. I recommend to use Progressive Dynamics 50 Amp Transfer Switch part # PD52. This 50 Amp transfer switch will allow you to hook up the 30 Amp shore power to the HOT 1 connection in the box. When you decide to upgrade to a 50 amp setup, you will use HOT 1 and HOT 2.

  • Can I Use the Progressive Dynamics PD52 to Replace a Furrion F50ATS
    Yes. You could use the Progressive Dynamics # PD52 to replace your Furrion # F50ATS; they're both rated for 50amps so they are compatible. The Furrion does provide a bit of extra protection against power surges though with it's 125/250v supply, so I do prefer that choice when possible.

  • Recommended Power Transfer for Generator Connection on 5th Wheel Trailer
    The Furrion Transfer Switch - 50 Amp # F50ATS can be added to your 5th wheel trailer along with the 50 amp power inlet like # A10-50INVP or # A10-50INBKVP. Most generator inverters will use a 30 amp generator cord, so you will use the Mighty Cord Generator Adapter for RV Power Cord - 50 Amp Female to 30 Amp Twist Lock Male # A10-G30450VP and then power cord # A10-5025ED. This cord is the shortest we carry at 25 feet long. This combination will allow you to power your refrigerator...

  • Transfer Switch for Use in RV that Has Progressive Dynamics 45 Amp Power Center
    Any time you have more than one AC power source you need to use a transfer switch like the # 34264403. This kit will automatically switch from the inverter power to shore power when available. But since you have a 45 amp power center and the transfer switch you referenced is only designed for 30 amps you'd want the 50 amp Furrion Transfer Switch part # F50ATS. I attached a picture that shows the connectors that this uses. You'd want to run 6 gauge wire stripped back into the pins and...
