Habe mir (more) FI-plug adapter for cellar and laundry concerned about hedge there dryer, washing machine and freezer. For the bathroom I'd fixed FI's take in the fuse box, as well as for (Home) workshop, as with IP20 switches neither drip-proof and dust protection offers (against fine sanding dust, etc.). But to be installed as a cheaper, more flexible and simpler protection in normal residential or cellars are the plug adapter top in price and performance!
