In this LearnElectrics video, we help you to understand, and to use, the resistance tables in the On-Site Guide and in Guidance Note 3.
They are easy to use, if you understand what they are telling you, and if you have the correct formula to use.
Some of the frequently asked questions have included …
How do I know what resistance to expect for a certain length of cable?
If I know the resistance, can I find the length?
If I measure R1+R2 for a 20 metre cable, do I have to include the length of the Line, and the length of the earth in the calculation, making it 40 metres?
In fact, what are the calculations and how do I use the resistance tables?
So in this video we will answer those questions, show you the calculations and work through some examples with answers.
