Great effort for a new starter aged 16 well done, almost perfect. Stick to the chalk line
bit of a tip for you. Measure the distance from the CU to the bend, make the bend, cut off the few centimeters of the extra conduit and have the perfect length. Nice work Millwall, keep the pics coming and I'm sure more little hints and tips will be posted up.

Not my chaulk lines its a old board only lines I did on the board was to get a plum line to get the CCU and light switch flush 
iv got some other feedback about the saddles to keep them less spaced out too and after a while hopefully improve my condriuit bends and doglegs

Another Consumer unit. (More Carp MK unfortunately)
Not 100% satisfied with this one, there is always room for improvement IMO.

Simon, that is perfect.
Absolute top quality install that mate :icon14:
You will have to do a lot worse than that, you are showing me up as the bodger I am!
You can't go around making other electricians look bad.
Wish I could find a fault on it.:devilish:
Ahh well, I have to say a nice bit of work there mate, well done!

Well it's an MK board for one,
Thanks for all the comments everyone.
I find this method works for me.
Arrange the cables so they enter the CU in the order of the layout.
Guts out, CPC's terminated first, followed by neutrals.
Arrange the Lines so they are inline with the MCB's.
Guts back in and terminate in to MCB's.
Everyone has there way i guess, this way works easiest for me in my experience.

Just as a comparison Simon, this is my last board on site:-
Not my best to be quite honest. In a rush, under a very tight deadline + under very difficult conditions. AND its a Proteus 3ph board lol, the odds were against me :rofl:
Yours is a work of Art, mine is just a bit of work Well done and that is the level we should try to achieve.

Whoops... I should have explained the photo.
25mm SWA was supposed to be terminated into the 3ph Iso BUT plans changed. Whilst long enough (thank God) we had to install a 3ph CT metering system just above the DB. Coming down is 10mm 5 core YY cable. PV install, 3 x YY from each inverter into a 3ph MCB (Iso switch as well as protection), feeding the busbar, going to the main Iso feeding the 25mm to the Grid via a CT meter. (Think of supplying electricity instead of receiving it??? It took a while for my head to get round to it lol).

Dave I bow my head in shame, not my call on the day (it is the way that the boss does things!)
This is where the 25mm ended up going to btw:-
The above are risk assessments/method statement photos. Could not take pictures of the install due to being overseen by some big "Area Electrical Manager" for this building. Shame really, I'm proud of that work. He took my number for a possible job position starting next year! Think he likes me

Your already ahead of half the rough shot sparkies out there, nice job

erm,,,,, this is not really my normal type of install, but I have to show it.
This is in a refugee camp in France. Some how got involved into building a school/classroom for the children. We took solar panels with us and a few lights, some how we end up with this.
1st pic is 6mm DC cable from the solar panels to the Iso then to the inverter/battery location. 2nd pic is the solar sparky throwing loads of cables together in the dark in the hope that it will work lol :rofl: We got it going, just!
I've posted this up because I want to drive into any Trainee reading this.... STANDARDS.
The above is a refugee camp, there are no standards, there are no laws/rules/regulations! Basically we could do the install any bloody way we liked regardless of anyone!!! BUT.... We are Electricians and we do the job correctly and with the skills we have gain via tuition.
Would you be happy with that cable clipping in your home? I would and this is a site with no laws,,,, but we have standards regardless of the location...... Just food for thought lads.

Well.... erm... It seemed like a good idea at the time.
Someone had a crazy idea, then bought/salvaged/recycled a load of materials to build a school! I just had to jump in with booth feet.
The start.....
Basically a bit of almost flat grassland
... it turned into this ^^^ a solid structure for the kids to learn in.
We already have our first student. Mandy, hopefully she will have a better life because of the bits of wood we put together making a classroom.
I'm sorry to the Staff/Mentors and all the Trainees for saying this....... The Jungle refugee camp is an absolute FOOKIG SH!T hole. It really is Hell on Earth. That was the hardest site I've ever been on, anything else is a walk in the park. Awh well the children have a school now. A place where they can learn and have a better life then what they have at this moment in time.
Amazing what 3 people from Yorkshire can do in a weekend.
Good on you and your team.
Been a while with no new posts, time to add one I think.
Just wrapping up this panel now, exhaust setup for the carpark of a block of flats. Master had me design and layout from scope of works, once the building is ready I'll be top man on site for the install, looking forward to it.

I have absolutely no idea what it is I'm looking at.... :willy_nilly:
Basic operation is controlling speed of an exhaust fan based on CO levels in the carpark. Also controls a vent fan in the garbage skip storage room, with external fire alarm trigger to change fan behaviour. I'll track down and post my controls schematic, that may help.
Super cool, ElectroChem!
How long did that take you to design and build?!
Inspiring stuff... cheers for posting!

Design about 3 hours, plus a bit going over options with the boss. Building the panel about 20 hours. Apologies for the rough drawing, this was my modified-as-I-go working notes.

Was going to comment on several points ElectricoChem then noticed your Sydney based thus I have no clue what regulations you follow for panel building (I only comment if it's destined for the EU market ),
Although I must say you need to work on your Schematic - I can't make it out, it's illegible
If I was going to give any constructive advice then I would say this panel wouldn't be legal as there is no cable marking, thus compliant schematics cannot be drafted and as far as I'm aware there are similar 'universal' regulations that all countries tend to follow and I would say your panel is in breach of a number of them. I'm not saying it won't work, most of my comments would be cosmetic issues.
What does worry me is the task the panel is undertaking, as it is undertaking 2 safety critical jobs and I assume is interlinked with the F/A system then I cannot see how as a design you could comply (even without knowing your regulations), this in anyway is no pop at yourself, but do question the company you are under instruction from and been taught by.
As the panel goes and your Trainee status, I can admit it looks alot better than my first attempts back in the day

I seem to recall a similar conversation the last time I posted a panel. I do actually have a colour scheme for this one:
Red/White/Blue/Black - 415V 3P+N
Purple/Grey - +24VDV/0V (earthed)
Orange - VSD I/O wiring
White/Black - analog wiring from CO controller to terminals (shielded 2 pair cable inside the ducting)
I'll tidy up the schematic then we have a guy to properly draft it in CAD for delivery to the client.

I added to my post if you want a re-read it, I cannot comment on colour coding as ours differs so much:-
-Blue - DC control
-Red - AC control
-Black - Power cables
-Orange - Cable that usually have external power source or ones that are tapped of the incoming side of main switch meaning they are not isolated with the switch (Cab lighting as an example)
We do not use phase colours within the panel exept for the actual power supply itself.
-We would have to segragate the low voltage terminals and the control terminals and not be next to each other.
-I assume the VSD motor cable are connected direct to the drive not through any connectors, usually you would use DIN connectors for all external cables and the drive output cables would be integrally screened, a screening clamp would also be waiting for the motor cable to terminate.
-The cable I'D (numbering) is missing as already mentioned.
There are a few more but I'm only comparing with our reg's here and in part I know some will be different but in other areas it's clear you must be breaching local regulation.
My biggest concern here is these fans are acting as a safety system or react to safety critical systems but I see no allowance for that in design, I see no redundancy in design if the function of these fans is to exhaust the build up of gasses or to limit the effects of a fire by use of the extract system. - like I said before, its no critisism to yourself as you are under instruction here but such a control system would need to be carefully designed with the input of regional fire service and building control if it was over here, in the event of a fire it may often be the case that the drive goes into a burn out mode and will ignore all overloads etc to ensure the fan operates until destruction (Omron model you have doesn't have such options if I recall).
Example - your garbage fan is switched off on the panel, the fire alarm indicates a fire in the garbage area, the Fire panel should then relay a signal to your panel to over-ride any normal status and bring the fan on to do what has been spec'd by the local safety authorities... as it stands it seems your are building a stand alone system that would just get a preset speed command if the fire panel sent a signal, this could only work if the selector switch was in the correct position.
Apologies for the listings here but building various panels for decades means I pick up on these things at a glance and hope you take them in the constructive context they are meant
.What it comes down to is, if your boss is happy then your --- is covered but just have a seed in the back of your mind about the points I make, maybe further down the line you can start bringing up these issues and score some brownie points.

Oh I certainly do, please don't worry on that score. You raise good points and some of them did come up in the design process. There are no set regs for colour coding of panel wiring here, it's often left up to us or the client may have a site spec. One common one I see is orange/grey for 24V with blue/white for PLC I/O and red/black for 240V.
Would have liked to properly label wires, but no room in the quote. If the panel were destined for one of our industrial clients then absolutely would be.
Good point on the terminals, I may well pop a divider in between the garbage fan and control terminals just to be safe. The outgoing motor cable will indeed go straight to the drive, I've seen braid clamps and personally like them but they seem much less common here than on Euro gear.
On the safety system side, the panel has to respond to the alarm but is not itself part of the fire system. I've integrated a fire alarm healthy relay that is held on by an external contact (or I'll rewire if the health signal is a voltage). If this is lost it will cut the garbage fan and lock the exhaust on bypassing the panel switch. The inverter does have an override signal, Omron doesn't make it obvious in the manual as it voids warranty.
Thanks for the feedback, as you've noted the same principles of good design apply whatever the specific laws concerned.

My very first consumer unit install. Open to constructive criticism, one rcd more heavily loaded as house getting extension so planning for future.

I think the boss wanted the bus bar leaving on ready for a couple new circuits from the extension that'll be installed next week.
The neutrals, I did them like that to keep them together since there's 3 lines in the 2nd breaker from the left - is that not the done way?
D
Darkwood
I would have to go against you on that point, you are supposed to consider expansion into the design of any board fit, chopping the busbar would IMHO limit any future additions without sourcing another busbar. I would although pop some insulating tabs on the spare busbar stabs. :ciappa:
I'm not sure about your local regs but 3 into one terminal isn't permitted where I am.
If you leave the busbar then I'd say you should have the spare MCB's on it. Again not sure of your local regs, just my personal suggestion. **edit** DW beat me to it, apparently it's all cool by the pool.

You can have as many cables in a terminal as long as it doesn't impeed on the ability of the terminal to clamp all the conductors securely without damaging them, its not best in design to use the mcb as a multiple joint but it's not breaching any regs as such.

Three in to one is necessary here as the neutrals for that circuit all have to be in the correctly numbered terminal for that circuit.
Three in one terminal is pretty common when you have the two legs of a ring plus a spur.
