I’m using this so I can switch between two breakers. 2 inputs and 1 output.
The reason why I am doing this is because I have 2 solar systems and battery. One for each breaker panel.
The output is going to a electric car. So instead of me running a long electrical conduit to my car, I am using the existing electrical wire and switching the input between the breakers.
I have been looking at other past post and people are suggesting a smart pool timers but it only seems to be turning disconnecting and connecting one input only.
What you’re looking for is an “automatic transfer switch.”
Be cheaper to make one with semi or full industrial relays.
