Universal Rotary Changeover Switch 690V 63A Cam Conversion Switch 3 Position 3Phase 12Terminal Main Switch Box JYW29-63/3 D303

Works great to switch from utility power to solar power - use this for my swimming pool pump- a bit tight to get all the wires in - but good quality and pretty robust

Omg save me a lot of money

It works, case is small working with 3 each -120 volt - 10 gauge stranded 3 wire cables was very difficult. After a struggle was able to accomplish getting it all together.

Solid switch. I have installed multiple. This one is a buy.

Es un buen conmutador eléctrico, lo use para instalar un generador a la casa. Separa los circuitos eléctricos. Debes consultar un electricista porque la elección precisa será basada en el consumo de tu hogar. Lo recomiendo al 100%.

Almost a year in place and... it works as advertised

The box is too small and there is no space for wiring. After connect the wires, I can’t turn the knob and switch cannot work. It’s a bad choice for my RV, no instruction manual.There’re serious defects in the internal structure of the switch It’s a dangerous product.

3 Cuz it doesn't come with any identification of terminals or directions ...nothing...you're on you own. But its pretty simple. There's videos on YouTube that explain how to wire it up.
