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...

In the previous note we looked at the approach taken by the standard to the sizing of cables and illustrated this with an example.  We then looked at one...

When selecting a cable, the performance of the cable under fault conditions is an important consideration. It is important that calculations be carried...
