If you have no idea how electrical circuits work, or what people mean then they talk about volts and amps, hopefully I can shed a bit light. I’m intending...
Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
We have had the Wiki with us for a long time now, but at last I have decided to say bye bye – more details on why below.

If you want to check a circuit is dead (not live), you should always use the three point method. First check a known live circuit, then check the dead...
Traditionally generation of electricity has involved rotating machines to produce alternating sinusoidal voltage and current (a.c. systems). With the development...
Electromechanical relays have been the traditional backbone of electrical protection systems. While over recent years these have been replaced by microprocessor...
