What is Zs, what is it made up of. We look at the different parts of a circuit, Ze, R1 and R2 to understand what is involved in the testing. How much current can flow, what is a fatal electric shock and how does a correctly wired electrical system prevent this. Understand the difference between an impedance and a resistance, understand why a disconnection time is specified. A short and to the point video that will help you to understand this fundamental test for safety.
