We are sometimes asked about so called magic numbers, those numbers that will allow us to quickly calculate and determine certain electrical parameters without the need to start searching through many pages of the Wiring Regulations or the On-Site Guide.
So here, we have looked at two such numbers that will help us to quickly establish Zs values for some of the common circuit breakers in use today.
We also look at whether we need to determine the tabulated values or the measured values, and what exactly is the relationship between these and why have two different numbers?
Once you understand the basics of this method, you will have acquired a new skill for life and leaving your books at home will no longer be a problem, in a matter of seconds you will know the Zs numbers to measure against during your testing.
