Electrical Bathroom Wiring Drawing... Comments / Advise Please!!!!

[DIYBlues]

Hi Guys
I’m no electrician but I’m going to do some electrical work in my bathroom and understand the issues surrounding Part P and the building regulations. However I would rather be up front and say I’m still going to tackle it (although I’m not a complete novice at electrical work, replacing my Consumer Unit a few years ago and rewired my kitchen).
I’ve done a electrical drawing of how I think the wiring could be done, I will be using Wago Light boxes and Wago Junction boxes. The lights are 9w each and although the fan isolating switch shows it in the bathroom area they are actually going to be installed in the airing cupboard nearby.

Because of the extracting fan units (Timed) I’m going to take the power for the bathroom and on suite straight from its own 6amp MCB on the RCD unit (protected after the 30mA breaker on the RCD)

Please feel free to comment on the drawing and if I’ve gone wrong somewhere or I need to incorporate additional protection / fuse please let me know.

There may be one additional shaving socket in the main bathroom depending on which mirror/cabinet I purchase.

Regards

Switch it on and see if it works !

Please, no

Not stating the obvious but the circuit should not be engaged until it has been checked by LABC - it does not matter if they dont know how to check it - LABC are meant to check on 1st fix and 2nd fix!

Yet again he might be getting his mate to sign it off for him and not doing any testing on it or several weeks after its already been engaged.

Like the pic, but just noticed that the neutral and cpc from csu to wago's in bathroom are incorrect...

There are a million and one sob stories that the OP might have about why he can't afford a sparky, but I really don't think he should given free advice on how to wire his bathroom/ensuite when it contravenes both the Wiring Regs and 'Part P' (assuming he's in England/Wales). He even states that he knows the work should be notified. As others have said, what does he propose about inspection, testing and certification? Funny how he's been quiet since post 1 but been around to 'like' various comments?

And I hope that those inclined to help this guy aren't the same people seen slagging off Electrical Trainee in other threads!

Hi Guys

Thank you all for your comments, I will include 3A FCU's into the installation, I'm assuming these go before the 3 pole isolating switches... should I do both 3amp at the MCB too?

To those that thought this a wind up its not I'm just a guy looking for some guidance

Special thinks to Dipzy for picking up the error on my dawing, I drew the eath wire going to the neutral and vice versa (I swapped the L N SL and E symbols around to make the drawing clearer but forgot to redraw the cables from the RCD to match)

For those who enquired I used Paint to draw this diagram which you can find on all PC's under Acessories, although doing it this way was long and tiedious but I wanted to make the darwing as clear as possible so you could advise me if I've gone way of the mark.

Sorry if I upset anyone by thanking them for their comments instead of writing a new post at 11:30 last night

you need to fit the 3a FCU so as to protect both the permanent and switched supplies to the fan/s. the easiest way to do this is to fit FCU upstream of the light/s.

It's not the fact that you are thanking people rather than posting, it's that you expect sparkies to provide you with technical help free of charge. I don't know what you do for a living, but I bet there's payment involved somewhere and you don't work for free? If you had initially posted on here that you couldn't afford an electrician (for whatever reason) I'm sure a local sparky might have offered you some help at a reduced rate etc

Plus if you can't inspect, test and certify the installation as well as notify Building Control for a certificate then you shouldn't be doing the work. Part P (for all it's flaws) was brought in for a reason, as a control to stop DIY'ers killing themselves and others. I appreciate that many DIY'ers do electrical work, but 2 wrongs don't make a right. Plus, there will be forum members here helping you giving advice and then bemoaning the guys that do a 5 week course to get 'qualified' and then ask on the forum for some help. I appreciate they are then working for a living newly 'qualifed' but it still smacks of double standards to me. Personally I can see the forum being open to a whole heap of criticism if they give advice to non-electricans (particularly when it is obvious you are breaking the law) if something were to happen and someone was electrically injured.

then again, OP might have a sparks friend who is prepared to inspect 1st and 2nd fix, test , and then certify and notify. makes me want to swear when a qualified spark with --- years experience is breaking the law by doing work in his own property, when a spotty faced Electrical Trainee who has paid his scam fees, but ain't got a clue, can do it legally.

The ultimate insult, I’m 2[SUP]nd[/SUP] to a Electrical Trainee.
Tel could you take one X out of the “years experience”, I don’t think any of us are that old!

 

[telectrix]

3 X's = 30 years. with your knowledge of latin, tony, thought you'd have spotted that.LOL.

 

[Knobhead]

OK XXXVIII for me

 

[ezzzekiel]

What hard part are you going to do for him?

oh i dunno maybe part p membership, insurence, calibrated test instruments and knowledge to use them. Its a special location and the cost to certify correctly warrants using a qualified spark

in 13 years of doing new build ive never fused a extractor fan ( except hoods) yee haa.. The way i would wire this bathroom would be to feed the isolator and do all the conections in there!!
