Look up before erecting any kind of pole! Someone in Burnley North West England though it would a good idea to put a pole, suspect wireless communications 1m away from some 132KV overhead cables. 'One wrong move could have resulted in a death’ say Electricity North West -...
When you do a voltage test the test instrument is checking is there a "pressure" difference between that point and another point. When it is testing the pressure difference a very tiny current has to "flow" in the test instrument. To allow the test current to flow it is a two pole device and...

I have just moved into a Flat that has the Bosch Easycontrol. Even though I do a reset it keeps asking for an intital installation username / password. How do I reset this?
If you are exporting a TT arangement then use the traditonal brass gland and do use some SWA and do the cable calculations. If the supply is TNCS (PME) or in come cases TNS then you will need to use a NYLON (plastic gland) at the load end and provide suitable local earthing arangements not...
It only gets too good if it is a PME network and you might get more than what the cable is rated for long term through the bonding conductor during a combined earth neutral conductor break. This could be seen with a substantial radio installation where great efforts are made for a function earth...
