Hi, thinking about next year pool season already.
I am looking to control my pool pump which runs off 240VAC (14/3 cable which has 2 hot and 1 neutral + 1 ground)
I have some heavy duty 30A high current relays, but not sure about using 2 separate relays (one for each hot wire) I’m worried what would happen if only one relay tripped, would it damage the pump etc.
is there such thing as a double pole/throw relay which would ensure both relays trip together?
Otherwise my current plan would use 1 gpio on my rpi to trigger both relays which should hopefully work.
Anyone switching any devices that have 2 hots and 1 neutral?
