Hi,
The consumer units in my house and my friend's seem quite old. I added the photos below. I'd be grateful if anyone could give me any comment on these consumer units? Do they need to be replaced to a modern 17version one. and how much it will generally cost for the replacement
It has six circuits in the main-switch plus another one for the shower (the white one on the left. But it seems no RCD or RCCB etc installed)
It seems the device in the bottom-right is RCCB for shower. The consumer unit is earthbonded to a pipe in the bottom-left. There are three fuse box on the main-switch at the top (one for 5A, one for 30A, I don't know what current the white one in the middle is for.) The white switch in the middel is for a ring-circuit in living room.
