The device on the right might be an RCD. In the context of the circuit possibilities for a few sockets fed from a 4-way CU, there are: A radial final A ring final A ring designed so any part of it can be isolated to be worked on without losing the supply Really? More like a way to...

Bit awkward to use as a way to alert that the fan is on....

That might depend on how much they did for themselves and how much they cribbed from others...

We don't know that. The radial circuit might be the second question in Task 8.

Probably, but wrt connecting it to a supply, that doesn't matter. No, it isn't. Read what is written. What is at the top is not a question, it is a heading. "Task 8. PVC PVC Cable: Radial/Ring Circuit 3 sockets" The actual task to accomplish is halfway down the page "Task: 8: Complete...

How did he decide what the csa and installation method of the cable was?

A very loud klaxon? Or this? https://www.ebay.co.uk/itm/327077822213 :ROFLMAO:

And nowhere does it ask for that DP switch or FCU, or whatever, to be connected in any way. One of the things people need to learn is the importance of installing according to the instructions they are given, not according to what they think the person giving the instructions "actually meant"...

Hardly a surprise, as Welshpool is closer and by implication the route is less hilly, so your observation applies equally to ICEVs. And to the amount of puff consumed if pedalling a traditional bike. Eh? I assume you meant miles per kWh, but even so, eh? mpKwh... mpg... identical...

Why should he bother when other people are doing it for him? Anyway - his tutor is going to think he's a star pupil.

No, you've bridged the ring in two places.

People tend to like that with final circuits. Why do you think it would be supposed to?

It's our old friend, the lollipop, so almost a ring. OK if the "stick" cable is 4mm². Or possibly 6. A red herring? Put there to see if the students can follow instructions, and not do things not asked for? Or sloppy workbook production - what's the betting that a future question is...

I'm wondering if you have an unrealistic expectation of the noise a fan will make.

There's a good chance of screw connections being available, so no soldering required.
