If either the fridge safe or the tv safe sees no neutral, neither of them will turn on the supply. So they do also check for a lost neutral.
I don't know where you picked up that they need to be registered. Registered with who ?
If you use either of them, it should not be necessary to claim for damages ....
I'm speaking under correction but Justloadit has a similar product and it will be interesting to hear his take.
Peace out ... Derek
