    Bad IR on kitchen ring final

    Hi Kerching it was just a fused unit so guessing it only isolates the line when fuse is removed. The boilers circuitry must have affected the IR reading through the Neutral. In the past this has never been a problem but then it's all down to individual boilers different makes etc affect IR...
