OK - I'm installing a Pentair Superflow pump with a 2 speed switch (part number 350822). I think I have he wiring correct but want to run this by you. The pump has 3 lugs marked 1, 2 and 3-4. I attached one power lead to lug 1, the other to the black wire on the switch. I attached the yellow switch wire to terminal 2 and the white to 3/4. I attached the common (black) power wire to the green lug, and finally the external ground to the ground lug on the case. Is this correct? Thanks! Jim

Yes, that appears correct

You have power to power, yellow to control, white to neutral, and the common to the ground, correct

Thanks - I thought that was correct. However, when i applied power, the circuit breaker tripped, and tripped, and tripped again. After doing some tests with my multimeter, I discover that if i removed the ground wire from the case, the pump would run BUT it would get warm/hot quickly and thermal off in 30 seconds, and then cycle back on / off until the motor was hot to touch. I'm returning the unit as defective and will try another unit. Does this make sense?
