Thread of things I'm unsure about.

[OhmSweetOhm]

Getting a lack of experience in my apprenticeship due to my company becoming more of a lacky company doing whatever they're asked of no matter what it is rather than being an electrical company.
This is worrying me a great deal as my AM2 is coming up in July and a lot of the things I've learnt has just been forgotten.
So I've made this thread to ask you guys any questions that pop into my head that I'm unsure about. So firstly...

2 way switching:
Do you bring a twin and earth in from the board to the light fitting.
Take a 3 core and earth away from the light fitting to the first switch (Brown-C, Black-L1, Grey-L2)
Then take a 3 core and earth from switch one to switch two?

How do you do two way switching by bringing the feed to the first switch?

Thanks.

Just finished my installation today. A lot of it was stuff I'd never used before :/ For example, the SY gland looked like an outdoor SWA gland, whereas the ones I've used have had 2 cuts down the sides where you take the sheath down and wrap around the gland. So I'm not sure if I did that properly.
Also the SWA glands didn't use a banjo for to earth the armouring. The glands they gave me had a thicker locknut which had threads in for M4's which you took an earth to. Had never even heard of those before. Good idea but much prefer the banjo!

Did the fault finding today aswell, managed to get 5 out of the 7 but not sure if they were correct so I'm pretty sure I failed that part .

I had an hour at the end of today testing. Filling in the sheets and almost getting the R1+R2's out the way. So tomorrow I'll probably have 2 hours to do the insulation resistance tests, calculating the Zs's, a PFC test, RCD test and functional tests and I think that's them covered...? Think that's enough time?
