T57 50 Amp Transfer Switch, Black

Fantastic relay I double stacked relays in my Sprinter van so that I can have three different inputs. Shore, gen, and then on the second relay I put the 3000 watt inverter into one leg there so there's three different power options and had rewire a few Breakers. I did all this on a lithium power conversion where I installed two 300 20 amp lithium low temp batteries. This relay was a cherry on top to make the system work perfect. I like this product cuz it's better quality than the other ones the screw down terminals are super heavy duty not wimpy.

Great swap out for my broken 2005 Holiday Rambler transfer switch. Back working great !!!!

After 7 years I had to replace my transfer switch. This was a numbers identical model. While installing a new Onan generator I discovered that the transfer switch had one less input than the old one. If you have a Keystone camper you need to put both neutral wires (white) into the same connection. The installation was pretty straight forward and everything is clearly marked.

the FIRST transfer switch delivered was installed in a 1999 Winnebago Adventurer. Tested one time SAT. A week later in Yellowstone National Park with no shore power, generator started but no transfer. To survive, I connected the generator to the shore power terminals and of course, removed the shore power connections. At this time, I found out both the neutral and the hot lead are switched! When back in civilization, I called the vendor. After several conversations, I gave them a credit card to have another sent. Three day shipping was about $30 but due to the travel schedule, it was the best option as their free shipping wasn't guaranteed to get to location before we were scheduled to leave. I removed the defective switch and tested it from a 120 vac source hooked up to the generator terminal (L1 and neutral supply the time delay board). The defective switch was turning on the green LED on the timing board and was switching the neutral line, but it was NOT switching the hot lead (L1 since my RV is 30 amp/120 vac.) Installed the new switch and the generator has been started several times with the time delay of around 30 seconds working as it should. Vendor should give back funds to my credit card as the defective switch was returned to them.

After installing my solar system in my 5th wheel (w/battery bank and 3000 watt inverter) I needed a solution to switch between the onboard inverter and shore power/generator. This has met or exceeded expectations. I am a fulltime RVer and I mostly boondock/dry camp. So I mostly run off my solar battery system. The shore power receptacle, in my case, is used for generator OR shore power. Essentially, the generator is backup for those rare days I don't get enough charge from the solar/battery system. I like the delay (20-30 seconds) on the generator side of the switch. I'm also impressed that when it does switch from the inverter side to the generator/shore power side it does so without interrupting power to my appliances in the 5th wheel. In other words, nothing flickers or turns off and on when I power up and it auto switches to the generator, and vis versa, when I power down the generator and it switches back to the inverter. This was a good investment....

Great product. Was a direct replacement.

This product is a perfect fit for my 2022 5th wheel camper easy to install great quality for the money . Just to give a little info please take a picture of your old one before you disconnect it so you have something to go back and look at if you need to and also make sure you are disconnected from shore power before attempting to do this work if not comfortable when messing with power please let the professionals do it for you

Take lots of pics of your wiring. Fairly easy to wire. Go slow and pay attention to where wires go. Some places were swapped on mine so took a bit longer. Not rocket science but again. Take pics.

Worked great
