[QUOTE="ProDave, post: 463805, member: 6969"] The transmitter needs a good RF earth connected. A porential (see what I did there) issue occurs if that transmitter is also connected to a PME earth and a fault occurs on the PEN conductor. Some will just disconnect the earth in the plug of the transmitter but then that leads to a different problem of different equipment in the same room connected to different earths. The only safe way to do it is the whole room to be on a TT earth, but then you are into dedicated circuits for that room. I'll bet there are a LOT of very dangerous installs around. [/QUOTE]
