Abstract
The current document discloses a ground-detecting direct-wire descaler that detects and indicates whether or not a descaling signal with sufficient current and voltage is produced or, in other words, detects and indicates whether the pipe or other equipment to which the ground-detecting direct-wire descaler is coupled is isolated from AC ground. AC-ground detection occurs both on initial power on and at regular monitoring intervals. In certain implementations, ground-detecting direct-wire descaler additionally detects and indicates whether or not the three-pronged outlet, into which the power-cord plug of the ground-detecting direct-wire descaler is inserted, conforms to UBC standards and therefore has safety ground available for use as signal ground. The ground-detecting direct-wire descaler only attempts to produce a descaling signal when safety ground is detected.
