TESTING Ze Zs UNDERSTAND THE DIFFERENCE BETWEEN Ze AND Zs AND HOW TO TEST CORRECTLY

This video is all about how to test the impedance of electrical circuits correctly.
We must be able to understand the difference between Ze and Zs and be able to identify which parts of an electrical circuit they relate to.
It is essential that all electricians understand what these two values are, how they relate to the Zs tables in the Wiring Regulations and On-Site Guide, and ultimately how they can have a major impact on the health and safety of the users of the electrical system and occupants of the building.
Get this right and you can confidently sign off and certify your work with respect to electrical disconnection times for fuses and breakers.
The video deals with a must know piece of information, a fundamental requirement for all electricians.
