I have fitted this item as per the instructions and it keeps tripping the immersion heater main fuse. I know nothing about electronics so any suggestions or assistance is appreciated.

Asked by: MarkusC
Hello MarkusC, Unfortunately Screwfix is unable to offer installation advice other than that contained in the manufacturer’s instructions. We would also recommend contacting a suitably qualified tradesperson for advice. Thank you for using Q&A, [BH].
