Oh go on then! So it's not the neatest you'll see but I always struggle a bit with neatness with board changes, especially when there are cables coming in from all angles! I am aware that the hole at the back is too large (as pointed out by Paul on a picture I posted before) but have only knocked out what I needed (parden the pun) since I received the feedback! We were altering the existing installation (half renovation type job) adding sockets and and some lights, we were also asked by the client to change the board. The change was fairly straight forward; none of the circuits needed lengthened and everything tested as it should. All simple stuff. A brief list of what I did:


1. Turned the radio on!
2. Prepped new board
3. Identified unmarked circuits (2 of)
4. Isolated board
5. Perfomed IR test
6. Marked up cables
7. "Unwired" board
8. Removed old board & mounted new one
9. Terminated circuits, performing ring tests as RFCs were terminated
10. Performed R1+R2 tests on all relevant circuits
11. Energised board
12. Finished testing including Ze, PFC, Zs's and RCD tests
13. Marked up and stickered new board

Job done!

After:

Managed to avoid top entry (unlike previous spark) so hopefully maintaned some IP rating!

Big thanks to you guys again, these comps are excellent!

Re: ********Competition Time***********

I had been working on a social housing tower block refurb in Liverpool. I was on the team doing the communal areas from ground floor to the 10th and even tho I messed up a couple of times on some angles, I think I did OK considering I hadn't worked with tray since my 2330 4years ago!

Re: ********Competition Time***********

And then there's domestic security lighting installation I did a few weeks ago.

Re: ********Competition Time***********

Pre-apprentice here.. this was some of the college work we did before christmas.. pretty proud of it due to it being my first attempt of conduit and trunking.. only had 1 shot at it as they were trying to save on waste materials.. View attachment 27590 The entire thing is made from 1 1.5m 50x50 trunking with cover and 1.6m (roughly) of conduit. Hardest part for me was forming the 45 bend on the trunking.
Once it was complete, we did the 3 dead testing procedures: continuity, insulation resistance and polarity. Havent started live testing as of yet.

Didn't do a practical class in secondary school so i don't think my metal work is very good, was interesting to learn though and i'm pretty sure the more you do these things the easier it becomes

Re: ********Competition Time***********

This is quite rubbish, and very simple, but I'll put this up as it was a learning experience.

4 core 4mm SWA, already poked through a plasterboard wall and cut to approximate length, I had to clip it to the wall and terminate in a metal 3P DB. There was an additional 6mm CPC, as the aim was to reduce Zs on the dist board circuits as low as possible.

View attachment 27601

View attachment 27602

I was told to cable-tie the CPC to the SWA rather than clip it to the wall. I was told to use a closed 20mm rubber grommet to pass the CPC into the metal DB, rather than use a stuffing gland. The environmental conditions are not onerous at all. The cable is not near/over an escape route, so I was happy to use plastic clips. The run is level, the clips are 400mm apart, as per table D1 in the OSG. Bend radius is about 12cm (minimum ~9cm, table D5).

If I were to do the same job again, with the same limitations on fixing materials, I would measure the distance between the two 90 degree bends and work out how to space the clips evenly (making sure they were spaced <400mm apart), I would try to get the SWA more perpendicular to the top of the DB before making it off, and I would put the cable-ties on the other way round so the knobble was at the top out of the way.

This task (which took me over an hour, including terminating the SWA in the board) taught me that there's quite a lot to think about, even for a seemingly simple task. I know this won't win any medals, but I thought I'd share and I'd welcome any comments.

Re: ********Competition Time***********

When I win can I have that Megger think in the first picure? The book doesn't have enough pictures in it for my liking and it's boring so I'll give it a miss if you don't mind.

As usual please mail my prize to Marvo when I win and I'll get it from him later.

Here's a DB I installed. It's pretty damn good and obviously better than the other stuuf shown so far but it's not my best work cause I ran of wire and sleeve so I had to make do with what I had but I think my method of swirling the wiring around the outside is much better and neater.

Re: ********Competition Time***********

View attachment 27631College work of the day was a Lighting circuit with a ring circuit.. nothing fancy but we had to make sure it was tidy as being used as a display peice.. the twin and earth cable is not the best to be honest..

Re: ********Competition Time***********

Apologies for blurry images! Part of a kitchen gas safety system that we put in. The new system consisted of two CO2 sensors mounted at the same level of the extract canopy above the gas cookers, and monitored the CO2 concentration during kitchen use. This system was an update on the older one, as rather than just shutting off the gas when the extract fans failed, it has a bypass button on the panel, which keeps the gas on, so the chefs can finish off lunch, dinner, etc. The CO2 sensors will shut off the gas when a critical level of CO2 is reached. All connections were numbered and connected up to a wiring diagram, linking the gas valve, fire alarm panel, emergency stops and CO2 sensors. Wish I'd taken more pictures now, as it was done before Christmas!

Re: ********Competition Time***********

At college today so i took some pics of my comp entry, its still a work in progress and I'm just about to start wiring it up. We manufactured the bends in the trunking and the tray, put set's in the tray and the conduits and also a running coupler in the galv conduit.

First time i'd done any of these myself so it was really enjoyable and hopefully i'll get to do some more in the future!

Re: ********Competition Time***********

View attachment 27787New bit of board work in college 2 circuits: 2-way lighting circuit looping through the light and a radial circuit with a fused spur to a light using a 3 amp fuse and 1.0mm^2 T&E to the light through mini pvc trunking

This project was to show the tutors what we have learnt in the past 3 months to make sure we understood the wiring side of things i think the hardest part was light due to having a few cables coming into it.

Next project is a PVC conduit project with a 2way lighting circuit that feeds to 3 lights will post when complete.. just the wiring and testing to do on it but college is holding us back cause we are completing the projects too fast haha

Re: ********Competition Time***********

Hi guys I know its a long shot but ill give the competition a try. Im on my first year of proper training and working with a qualified electrician Im also currently doing my level 2 and will be doing my level 3 thats if I pass my level 2 fingers crossed. Anyway we have been working on some new builds. one day were fitting back boxes and pulling cables the next day were second fixing. hear are some pictures of my second fix for you guys to look at and comment


fitting a consumer unit with a qualified electrician watching and advising.. I was sweating....
1. carried out a risk assessment
2. unboxed the consumer unit
3. prepared the unit for wall mounting ensuring I had a secure fixing and the unit was level
4. wired up new board
5. carried out all tests needed
6. Performed little R1+little R2 tests
7. Energized board
8. Finished testing Ze PFC Zs and RCD
9. made sure board was correctly labeled up so that no confusion or error was likely to happen while future work was carried out
View attachment 27794View attachment 27793

fitting a smoke detector
1. carried out a risk assesment
2. unpacked the smoke detector
3. read all instructions
4. located area for fixing
5. had to put wooden lats in ceiling as no decent fixing was available
6. secured the smoke making sure cables were well out the way of screws
7. stripped cables to correct length. well what i was comfortable with
8. wired smoke
9. put smoke back together ensuring it was secure
10. tested smoke
11. put dust sleeve back over the smoke as building and painting were still being carried out

View attachment 27795

Fitting a single socket
1. carried out a risk assessment ( my mentor is a devil for this but I suppose its better safe than sorry
2. unpacked single socket
3. took screws from the back of the socket
4. stripped cables to desired length
5. wired the socket pulling on each wire to ensure all connections are secure
6. earthed the metal back box ( apparently its not in the regs anymore but mt mentor likes to earth them)
7. pushed the socket flat to the wall then pulled back towards me ensuring nothing has became loose
8. screwed the socket to the wall
9. tested

Re: ********Competition Time***********

My entry:

My entry board for a sparks competition being held on the 18th:
View attachment 27850
Two circuits; One lighting circuit Switch 1 controlling light 2 and switch 2 controlling light 1 done in 20mm high impact PVC Conduit with the other circuit being a ring final with two single sockets, a joint box and a switced fused spur. Both circuits are connected to a Garage Unit(A small consumer unit basically) due to my board in college being a bit smaller than it should have been I was told to move it down by 150mm.

Forgot to take pictures of the first fix but started by measuring and laying out the back boxes and GU then by shaping and cutting the conduit to size:
View attachment 27851View attachment 27852View attachment 27853View attachment 27854
90 Degree left bend, 45degree 50mm offset, bending spring used to bend the conduit and the circuit as a whole.(And yes the blue PVC tape was taken off the wires)
View attachment 27855
It was only my third time bending conduit so these are the practice pieces :lol: all the 90degree bends were too tight and the radius needs to be at least 2.5x the diameter of the conduit.
View attachment 27856
Then used a cable pull to pull singles through the conduit with a permanent live going from the GU to SW2 then from SW2 to SW1.
View attachment 27857
The Garage Unit. Which isn't my fault it's so rough, it was the only one the college had :lol:
View attachment 27858View attachment 27859View attachment 27854View attachment 27860
Then began to run 2.5 and clipping every 30mm, beginning of a run and before/after a bend(pictures taken later since I forgot to)
Once first fix was done I began second fixing starting with the joint box since they're so awkward :| especially so low to the floor.
View attachment 27861
Now looking at it two of the wires could have being sheathed less so there's around 10mm in the box.
then went onto the Switched fused spur then the switches then lights, sockets and finally with the garage unit
View attachment 27862View attachment 27860
On the GU I was sure to twist and double over the connections for the lighting circuit as it's good practice with one wire going into a terminal that can accept two wires.
View attachment 27863View attachment 27864
Beautiful ain't it? and being sure to leave plenty of wire in case of future alterations(obviously not in this case but in real world installs)
View attachment 27865
in the case of the Live and Neutral for the ring final I didn't double over since it's two cables into one termination but did for the earth since it's slightly smaller in diameter
View attachment 27866View attachment 27867View attachment 27868
Garage Unit wired although it is messy.

Board done.(And I forgot to get a photo with it all done)

A shotgun made by one creative classmate complete with working pump action :lol:

This post took quite a while to type out and upload each individual picture also if a mod could be able to rotate any pictures as needed if it isn't too much trouble please?

Big thanks for glenn for being generous enough and putting in the effort for this competition and robb for his donation. Going to have a look at the other entries now, good luck everyone.

Re: ********Competition Time***********

Eh up

Right, this will be familiar to a few, it's a 2365 level 2 board. Here's what I'm aiming for:

View attachment 28027

I've seen more eloquent ways for fabricating a 90 degree bend, but that's what I'm copying, so that's what I'll do.

So I started like this...:

View attachment 28029

Starting to take shape...:

View attachment 28030

Time to start cabling it up...:

Alright! Out of time. Leave it in the workshop, hopefully they won't need any bits off it for the Monday night class...

Oh. Ah well. Guess that's that, then!
