KEYMOO 63A Rotary Changeover Selector Switch with Exterior Box, 2-Way 3NO 3NC, 660V 3 Position 3 Phase 12 Terminals Universal Selector Switch for Solar and Grid Power Switching

We have been experiencing power cuts where we live abroad. This device makes it convenient to switch from street power to Generator power seamlessly. It works great!

Used to switch the power source in our 5th wheel between solar and shore power. It handles the 220v from the inverter or the main power plug. It's a bit of a pain to wire the inside and get it all in there, but it's a decent unit

This is perfect for my RV and so much cheaper than a transfer switch. I don't have much room to work with so this switch is perfect. I had to jump some of the terminals to get it to work the way I needed but simple ohm test got that done for me, so one way is shore power coming in and the other is inverted battery. No danger of leaving the inverter on and plugging into shore. Didn't need it for 3 phase so some terminals are extra but it does what I need.

i had an electrician wire up this switch between my ceramic kiln and my garage heater because i didn't have the juice to run both at the same time, and now that will never occur accidentally.

I have been using it for more that 6 months now for switching electricity from my solar system or the energy company to my home with no problems it is a good product got 63A item. Wired it like a Y.

Purchased to use as a changeover from hard line power to generator. Worked perfectly!

Installed with no problems.Operation is nice and smooth.
