Guidance please - C&G L3 electrical installation - Hotel extension project

Hi folks, I am fairly new to this forum but it looks like the community are quite responsive.

We have been handed a project to complete in our own time. as it’s evening college i have limited access to resources and guidance from my teacher with regards to this.

I have completed question 1 which is for the ev charger. I have also started question two, showing where luminaires and sockets are located, along with a wired drawing from the sub mains.

For those who have done level 3 and completed this project, i will be really grateful if i can upload what i’ve done so far and get some guidance from the online community. however a polite request to hear from those who have done this project.

that’s enough of my waffling now! thank you

Welcome to the forum! Good to see you've tried the assignment - some people come on here just asking to see other people's work so they can copy it.

This is a ring final circuit so how have you calculated the R1 + R2?

i’ve referenced from page 218 on on site guide. should i not be using that page for ring final circuits? if you can advise that will be great

So from r1 and r2 how have you got R1 + R2?
Don't have OSG.

Hi all,
I am doing level 3 design project assignment where I have to calculate the lights for the pool. Area of the pool is 148m2. Light description as ''Pool LED 4 Asymmetric Floodlight, 10 067 llm 4000 K LED with Touch Dim / Digital Addressable Lighting Interface (DALI) and RAL9011 Black Finish''. Can someone able to help me with the calculation please? In the Lux value should I use the average lux value 400 or the LLM above? N= 400 x 148 / 0.8 x 4000 this calculation will give me around 18.
