Most installations involve some form of lightning protection system which is connected to an earth electrode. The function of the earth electrode is to...
It wasn't so long ago I was telling someone that I don't use rules of thumb as most things are easily calculated anyhow. As it turns out I last week...
From the earliest times, humans have found ways to create light. Pre-historic peoples used natural materials (moss, grass, etc.) soaked in animal fat and...
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...
A UPS is an uninterruptible power supply. It is a device which maintains a continuous supply of electrical power, even in the event of failure of the...
