2330-206 Practical exam(Bay in a Day)

[Bridge-Burner]

Hello
I have my 206 exam this week and am somewhat apprehensive about it. i have no experience in the trade, am clueless about most circuits. This one is a radial circuit I think. Is that the same as ring? We are expected to fit armoured cable as well.
Does anyone have any advice for me? Apparently we can do the fitting first then the testing the week after, I have no idea how to test either, can't even remember what to test for, it's three tests such as polarity and Earth continuity etc. If I fail the testing bit will I have to do the whole lot again?
Quite worried I'll fail. Are there any pictures or guides? Are they all the same or do different colleges require different layouts etc? Is there as much theory as the 205 practical? That was annoying with the odd questions on capacitors etc.

Thanks in advance

Little tip for you to save time and frustration.

When you are doing the small run of swa from "main isolation box" to the c/u, measure as close as possible. If you don't get the correct length, if your out by a few mil connect the swa to your c/u and then take the mains box off the wall to the correct height for your length of swa then re-attach the box.

Nothing in the exam to say you can't do it .

Make sure the examiner can identify every cable in the c/u just by looking at them and make sure the c/u is tidy and not a rats nest with each L, N and cpc in the correct term in the numbered bar.

Tug test each terminal, make sure that everything is perfectly vertical or horizontal. All clips are 30cm apart. Each accessory use min two screws to fix to the wall and that they are secure. Don't put light switches up side down. Leave enough wire in the back boxes but not too much. Follow the measurement details on the diagram.

Don't know what they want now but when I did it.

Swa to c/u.
1 x rmf.
1 x raidial.
1 x one way lights.
1 x two way lights (or intimate, can't remember)

Using a combination of t+e, singles and mims (might have been a small piece of fp200 as well). Clipped direct, pvc conduit and steel conduit.

Good luck, take your time and do it right.

One last thing, check all lug nuts are ok before fitting. Saves pulling them off the conduit if the college ones are knackerd.

If your not that confident just take your time, think about it. Do one circuit at a time, it only consists of 3 wires and that's all you have to worry about at any one moment.

As for the testing? I don't think you will be testing it, they may want you to do a continuity test at most. Double check this with your college and ask what tests you are required to do, then come back on here and ask for help.

ring final

edited as some can`t see the pictures.
basicly if you look at the ring final there is a cable leaving the consumer unit and one returning. if you were to omit the returning one there would just be one cable at the last socket as this would be the end of the radial circuit.

also the two sockets in the middle are a spur off the ring

i have 206 next month too. good advice above is dont panic, one circuit at a time. did you not have to do planning for your assessment . where as your givein a drawing and you have to link up all the circuits like dot to dot and do a materials list and tools list from the layout drawing.. i have page on swa-terminating if you want it. and swa is easy once you do it once.

Okay thanks for the excellent advice people. Some good tips. I'm mainly worried about wiring it in the correct manner. Does it matter how they go into the consumer unit?
I have my exam tomorrow
So a ring circuit is radial circuit? Literally just the wire flowing like a river? What do the spur/offshoots constitute? Could that be considered a radial circuit still? Not sure what we have to do testing wise, think it involves three different tests? Such as Earth continuity, Earth to live, Live to Neutral(can't remember what that one's called) and polarity maybe?
i=p/u not sure what you mean by swa terminating?
Sorry I replied late just been a bit busy if you have any more advice for me I would be eternally grateful

Hi everyone I managed to get it delayed till tomorrow instead.
So how is best to appraoch it? as in what order? Know you have to put the socket boxes on first, then fit the coduit etc. Bit worried about the metal conduit as I don't have much experience of it and if you get it wrong i don't think they give you any more? there is metal conduit up the wall and across the ceiling into a light fitting, the piece that fits the fitting and conduit together I've never seen before and have no clue how to fit.
so this wiring lark, where do I start? a box at at time? then just run it round to each box? the tutor showed me this time-saving technique where he fed a load of wires through the coduit at once, I was lost on it though. I don't have a very practical brain it seems.
Any tips anyone?

Also I was watching someone do their work and they chopped off the Earth, fed the grey into the neutral and just tucked the black behaind ath the back of the c/u. is this correct?

 

[simpson93]

was in the same position as you last year. i did a ring and 2way lighting with armour run i think and mostly i conduit.

as for armoured black as neutral grey as cpc is what i do if its 3 core

as for your tests i think it will be just dead tests: continuity of cpc continuity of ring insulation resistance and polarity which is verified from continuity (check some vids on youtube for those quite handy)

 

[Bridge-Burner]

cool, does it matter if I use black or grey, as long as I mark it?
Yeah I've been looking at youtube vids, much more helpful than the tutors themselves!
