I'm so pleased Mrs Murphy and her family are safe and well, though with Christmas approaching it will be stressful for her.
It is good to see a manufacter paying for these recalls, but I remenber something like this happening a few years back, and having to change protection devices. I will always remember the attitude of customers as you called them to tell them that the CU you fitted a while back had to be modified, as invariably they ask why, and hear the silence when you tell them that the manufacter as advised this.
When you arrive it's then the look they give you and again 9 times out of 10 they seem to think it was your fault that you fitted a potentially dangerous piece of equipment. No explaining ever seems to change their mind, and in some cases the good will lost is quite large
