Hello there,
Installing a pool motor, 220v hayward northstar two speed. Could not find a double pole 40 amp GFI, electric supply store recommended two single pole 20A GFI's sharing a neutral? Does this make sense. I have a 40amp double pole in the main feeding the sub via the sub panel lugs, looking for a min of 20a at the motor (draws 14a). I greatly appreicate your help. AL
