Hi - This might be a stooopid question, but... I want to check that my house electrics are properly grounded. When wiring up my boiler, an electrician extended an existing ground wire (previously used for an immersion that has now been removed) and bonded all the pipes. However, I would like to ensure that the wires are properly grounded.
How can I test this? And preferably not just test the wire to the consumer unit. How can I tell if the main earth wire from the consumer unit does go to earth?
Also, I have just bought an electric guitar and some humming is noticeable. One of many possible reasons for this is poor earthing of the circuit that the guitar is plugged into via the amplifier. So I would like to rule this out.
Thanks
Dave
