Dick Smith's Fun Way into Electronics Volume 1 (first published 1979) has the following warning at the end of the Crystal Receiver Project... "NEVER use as an earth connection, the 'earth' pin from a household power outlet. The earth in a mains power system is there for your protection, and should a fault develop while you are using your crystal set, etc. YOU MAY NEVER GET THE CHANCE TO BUILD ANOTHER PROJECT."
Is this correct? Surely, you are only going to get fried if you are BETWEEN earth and phase. To get done from your crystal set, phase would have to come into contact with earth AND earth would have to be 'un-earthed' (as in someone removing the ground rod).
Can anyone clarify this?
