Why does the RCD trip immediately upon power up?

  • If this is a new installation, make sure that the RCD is wired correctly.
  • Disconnect all the components (i.e., pumps, blower, ozonator, heater) and plug them back in one at a time to verify which component is causing the RCD to trip.
  • Check for any loose connections or cut wires in the box.
  • Plug in a new transformer
