How to Calculate Total Earth Fault Loop Impedance - Applying a Temperature Factor to R1 + R2

I love calculations 🤗

Audio is terrible

Audio sounds good to me, fantastic reminder of how to do the loop impedance calculations, great video Marcus as always 👍

Nice funky wall paper

Not sure when this video was made, I know the data is the same, but surely you should be showing the latest O.S.G (BS 7671:2018+A2:2022) Brown one... Page 218

Thank you from me too.
Clear and concise.
Having done 16th/18th/2391 but never used on a daily basis, I go rusty quickly.

How would you do this on a ring main?

Top explanation but you got my lost in jupiter when u got the "random" (Ze) could you please explain how u got that value for those who might struggle to get it. Thank you, this video has been a great example for my project. Just the Ze thing got me lost. I did watch the video backwards and forwards. Just Ze 🤯 thank you

Nice video Marcus, I assume after the install is complete the Electrician can test and report against the design values?

It's Temperature

what if i wasnt given the length?

I'm struggling to find these tables in the eighteen edition book. This is handy for the on-site guide. But my exam for the 18 tradition requires me to know where this is in the big book. Can anybody help here?

This is fantastic guidance for the smaller on-site guide. But I have my 18 edition coming up and I. 'm struggling to find the pages within the 18 edition for these caculations

My old primary school teacher taught me this great spelling technique… “Mr Parker will always lose his Temper-at-ure!!” 😉

What about a ring circuit?
