2365 C&G L2 10 hour exam

[uksrevivor]

Good to hear DeanoRN and congratulations on the distinction. I was the same more hands on than classroom based and I did struggle with the electrical theory on level 2 but managed to get my head into the books and online and passed it, bear in mind I have not been to school in over 30 years lol so it was difficult for me. All the school leavers got the formulas and maths quite easily so earlier in the year I knew I would find the formulas and maths hard so I helped a lot of them through their practical modules and they returned the favor by helping me through the formulas and maths I needed to pass the exam.

Has anyone got any info on how to carry out the test. Looking for a list of procedures so that I can get it all in my head before my exam.

If you're on about initial verification tests: CRIPPER

--- Dead tests ---
C - Continuity of earthing conductors (main earth, bonding, CPCs)
R - Ring final circuit 3-stage tests
I - Insulation resistance
P - Polarity (this box should be ticked if you've done first and second task correctly)
--- Live tests ---
P - Polarity (supply polarity)
E - Earth fault loop impedance (and related - so Ze, Pfc, Zs etc)
R - RCD testing

and then finish it off with functional testing.

Stolen from Alan Lynch, well worth investing in his books.

Hi, I've got my level 2 10 hour practical on Monday and I wanted to check I've got my 2 way lighting circuit right.

It's a 2 way lighting circuit in steel conduit using 1.5mm singles. I've attached a picture of my circuit diagram that I'll be following. Could someone check it's right.

Not quite, you need a permanent live to common on one switch, and switch live from the common at your other switch to your light fitting. If that makes sense

 

[howlinstein]

So a blue neutral with a brown sleeve from the common of my second switch to the live section of the lighting fitting?

blue neutral

You dont need a neutral at any switch, you said you was wiring with singles in conduit, so theres no need to use a blue core and sleeve it, just use brown.

 

[howlinstein]

Thank you. So it should look like this?

Great thank you

Great thank you

I'm not being funny mate, but surely you should have covered this loads in the workshop before even thinking about taking the assessment

the switch on the left the com should go back to ceiling rose in the S\L terminal? i think thats right?

One switch has a permanent live in the common, the other has a switch live to the light fitting in common, it does not matter what switch it is.
