5-3. Dry pit attachment
In case there is no water ordinarily or there is a fear of water being emptied, dry pit
attachment is used. When the water level drops, the electrode points come in contact with the
contact plate of the attachment and cease to further go down.
Therefore, the electrodes are earthed as are when floating on water.
