I have been almost everywhere installed this device protection in my house. Always fits with pure and meets (hopefully) its purpose. The beautiful, he is invisible. If he then but should hit sometime, it reports the acoustically. Then replace hip. The part is thus suitable only for outlets to which one comes close. Incidentally, makes this protection only in conjunction with a coarse and a medium protection sense. So always consult the electrician. Are all protection levels available, the fine protection has a range of about 5Metern cable length. This means that the protection is effective even then, when the device to be protected is connected to the "proximity" of this part.
