Would this work through the 240v/120v convertors that Maplin sell?<HR></BLOCKQUOTE>
These work as transformers, therefore the coils arent connected. Therefore i think its highly unlikely that the X10 commands will be sent from the 120V coil to the 240V coil.

How is the X10 data superimposed onto the mains ?
If it modulated (ether frequency or amplitude)
If so I would have thought it would pass through a transformer
If I am wrong I would be happy told differently

HardwareHacker:
The X10 is encoded as the presence or absence of an 120kHz burst at the zero-crossings of the AC cycle. It can be anywhere between 200 millivolts and 7 volts (though I've seen it both more and less than those numbers).
The transformer is designed to pass 50 or 60 Hz. How efficient it is at 120kHz probably wasn't considered in it's design.
So whether or not the transformer passes X10 will depend on:
1) The original strength of the X10 signal,
2) The coupling efficiency of the transformer at 120kHz, and
3) The sensitivity of the target X10 receiver.

In light of the technical information it may not be reliable
The point I was making is just because the two coils are not connected it doesn’t follow that it won’t pass the data
As the unit is not designed as a safety device they could use an auto transformer
