This is similar to what I'm using now and I called 'supermarket' device,
hm? And perhaps like the Furman device too, I don't know if there's a
difference.

IIUC houses that were build after the second world war should be
pre-protected, but houses that are older could be without any
pre-protection. The later a house was build, the better the
pre-protection and without pre-protection as far as I understand, those
devices are completely useless.

I don't have enough serious sources, the best seems to be the German
Wiki referring to DIN VDE.

'Perhaps' next week or so, I'll do some more research.

Thank you,

Ralf
