What is Zs? What is it made up of?
In this video, we look at the different parts of a circuit, Ze, R1 and R2 for example, to understand what is involved in the testing of this part of the circuit.
How much current can flow, what is a fatal electric shock and how does a correctly wired electrical system prevent this or reduce the risk of serious injury?
This video will help you to understand the difference between an impedance and a resistance and to appreciate why a disconnection time is specified.
This is a short and to the point video that will aid in your understanding of this fundamental test for safety.
