Hi I'm currently doing C&G 2365 Level 3
I'm working through the 305 design assignment (Swimming pool, hotel etc.)

Other then this assignment I have 1 exam for inspection and testing and a few practical days before completing.
I have done a fair few searches on google about this project a lot of the time bringing me to this forum.
I just wanted to check I'm doing these questions correctly. I feel confident with most except a few

Q2 d. Show how each circuit in the new hotel extension is to be arranged.

Is this asking to draw the circuits? I have done it this way. So from a submain in the hallway cupboard, distribution circuits to db's in each room (in purple). Then from the submains inside rooms, 1 circuit from the db to each socket outlet and fcu (in green). 1 circuit from db to air handling unit (fused spur) in red.

Then Q3 select with the aid of manufacturers data, suitable protective devises for this contract.

I was going to use 61009-1s for all final circuits, 60898s or 88s for distribution circuits supposing they dont require rcd protection, I assume surface run etc. Also 60898 for fire alarm circuit.

And finally filling out the table Q4

Ib is P/V
In should be equal to or greater then Ib
It is tabulated current worked out from In/Ca x Cg etc.
Iz is the curent carrying capacity of the chosen cable + method of installation?

I can upload pictures if need be.

Thankyou very much!

Hi Sam,

Also in the process of doing this.

You have to show calculations for all the circuits within the table. Took me a very long time, still actually completing the calculations.

The drawings sounds like you’ve done them right, just remember with the pool/cafe to keep circuits under 30m. I had to add either more boards or split the circuits to stay in this. The specifications does give you all the details you need. Don’t forget the drops to the switches.

61009-1 for every circuit is fine as well. You have to use manufacturers data to provide reasoning why you’re using it and if it meets the Pfc. I’m just about to do this so will happily update you once it’s marked.

For the calculations, I’ll check what I’ve done and update you as I’ve had it marked and okayed for the circuits I’ve done so far.

About to take in question 6 diversity so need advice on that as well.

All the best and will update you on calcs asap

Thanks for the reply mate! Been a bit busy lately so haven't got much more done. I missed the 30m limit at first but was only lighting that exceeded so easily changed. I've done most of the calculations now just need to do the basement area. I'm guessing I'll have to do calcs for my distribution circuit down there to determine the Zs and Pfc of the final circuits.
Did you have to apply the factor for conductor resistance at maximum operating temperature? Wo calculate r1+r2. I applied the factor for ambient temperature and then again for maximum operating temperature but think I should have left out the ambient temp factor...
I can send you my calcs and see how they compare?

Thanks

Hi both, I am currently doing the same project! did a post last week but no reply sadly. i would be grey grateful if you could help provide some guidance as i am struggling on some questions. i am also a bit worried that the drawings need to be done to scale which i havnt done. any help at all will be amazing. this is for the hotel extension project 😃

Hi Sam,
I am also doing the same project on design assignment unit 305 2365 level 3. if you could help me with this projects? i am bit confused regarding circuit summary and names and what shall i add to the list. thank you for you help in advance and really appreiated.

Hi, If you had completed this project, can u provide a detailed explanation of that or just share the completed project. That could also helped me with that.

Why would anyone share their hard work?
Have you started your project?

yes just started on the project. If someone can share their work, it will be helpful for those who want to do. My project is similar to those so if anyone can share, I might get my project done. The key concepts and ways to solve the problem would definitely help someone to do their own project.

Summary: If someone can send over to me all their work I will be able to complete my assignment. Thank you. Word it how you like I would be embarrassed to post such and would rather be up day and night working then go that route.

Feel free to ask questions on here but someone handing you a completed project is not the way forward. I assume you are fairly conversant with circuit design?

Your profile states to are a qualified electrical engineer?

Sure, I would follow the rules and guidelines for it.
Well that is good to hear and a lesson for all to adopt.
But...
Just to confirm my understanding (old and not always with it), my understanding being that now as it once was, the rules and guidelines require the project to be all your own work and not the work copied from some other person and handed in as if it was yours (?)

After all why would anyone want to do anything else? More so when the intention is to one day work in a career with a legal requirement for competency. Where the safety of life and property is at risk from those who present a false record of achievement.

Anyway good for you for following the rules and guidelines
