How do you use a dado blade on a table saw effectively?

To use a dado blade on a table saw effectively, first, ensure the blade is compatible with your saw. Adjust the blade height to the desired depth for the cut. Use a dado throat plate to accommodate the wider blade. Set the fence to the correct width for the dado cut. Make multiple passes to achieve the desired width, moving the workpiece against the fence for each pass. Always follow safety precautions and refer to the manufacturer's instructions for proper usage.
