WFCOT30 30 Amp Transfer Switch

Very nice switch

Everything matched easy to change and went smoothly

Hooked this up in my RV to separate the shore/portable generator side from the invertor side. Switches over nicely as intended and hasn't skipped a beat. Solidly built, rather rugged and while I haven't had it all that long, I would believe it would last quite awhile based on how it is built.

So far this has worked great. Easy to install

Same mounting as the original unit made it a simple swap over

If you have a WFCO load center in your RV, without making your own, this is the only game in town. That said it does feature a high quality transfer mechanism and the control board does allow option bypass for the 30 second cut over (ie generator stabilization period) if using another source such as an inverter.Plan your installation to permit easy replacement. This is not the case for me due to the location of my load center (near the ceiling above the reefer).Mind the hands while handling; there are some sharp edges that could be better finished.My theory on failure is it needs heat sinks and/or fans. It gets really hot in my installation location as well…

Buying this was inspired when we arrived at a campground in a heavy rain. Getting out to connect to the Pedestal was not a fun experience. It would have been nice to just start the Generator and wait for the rain to stop. Installation ABSOLUTELY Requires RV Electrical Experience and Skill. Not for the inexperienced. It also requires a LOT Of Planning for the DIY Types. Do NOT Attempt without a great electrical skill set. For those who are skilled this is a great project in the “off-season” (when is that)… Now when we boondock I do not need to get out and plug into the generator. So much easier for me now.

My RV transfer switch burned out so needing a new one I looked to Amazon. Exact same one that came with my RV. Just six wires to connect and electricity was working properly. Make sure you turn off 12v and 110v before working on the transfer switch.

Very simple to install and works as it should.

Attaches perfectly to (WFCO WF-8955PEC-B-LIS Power Center with Lithium-Ion Switch - 55A, Black) and shares the same space. I don't have an onboard generator so I connected shore power to the generator input on the ATS since this is the dominant input. I feed the ATS from my 400AH LifePo4 battery pack via a 3000 Watt inverter connected to the shore power input on the ATS. If I need to use my generator I simply plug my shore power cord into it and it is automatically dominant. It charges my batteries and runs everything in the rig as normal. It seems to me that this ATS is labelled with an onboard generator in mind. All the same, if I had an onboard generator and was able to connect to shore power, I would still expect shore power to be dominant to avoid running the generator????? Labelling aside, it is a perfect setup so far, instant switchover in my setup (turned off the delay since inverter power is instantly available) so nothing turns off or resets. I also have a 400 watt solar charging system when off grid and it provides charging along my WFCO setup.Just remember - you must to turn off the converter/charger breaker to avoid charging your batteries with your batteries. :)

This switch appears well made and is what I needed for my lifepo4 / inverter conversion on our travel trailer. I ran into a problem with it as it is primarily made for a generator setup. When I connected it as described and turned on the inverter it tried to charge the battery from the battery which doesn’t really work as it makes a loop in the system and will eventually run the battery down. I looked on google and youtube for clarity on this and the best advice came from a previous Amazon reviewer who had the same issue. You need to disconnect your CONVERTER input power from the circuit breaker and re-route it to the SHORE POWER input on the switch with a 15 AMP fuse so that it cuts the power to the CONVERTER when the INVERTER is switched on. This works well and everything plays happily together. WFCO should clarify this on their instructional videos as I am sure there are a lot of RVers who are upgrading their units for off grid camping with solar panel systems and leaving the generator at home.

Facile à connecter et fonctionne très bien!

came fast works great
