Regulation 543.2.7 where part of the protective conductor is formed by conduit trunking, ducting, or the metal sheath and/or the armouring of the cable, the earthing terminal of each accessory shall be connected via a seperate protective conductor to an earthing terminal incorporated in the associated box or enclosure.
543.2.4 (i) its electrical continuity shall be assure by construction, or by suitable connection, in such a way as to be protected against mechanical, chemical or electrochemical corrosion.
I can't remember the other regulation number I need.
But it basically states all armouring of cables has to be earth at the distribution board end and the supply end, by a banjo, and must comply with regulation 543.2.4(i)
If you need any more advice you have my mobile number just give me a call as it might be easier than waiting for me to reply on here

And to add as I forgot to above - by ways of earth with a banjo, it needs a banjo, with a hole drilled through a BRASS bolt put through with a CRIMPED earth cable coming off of the bottom into the earthing terminal of the accessory.
And EVERY termination like the ones on the fuse spur require this.

the protective conductor is not formed by conduit, trunking etc
it has a seperate conductor !
the armoured cable having an metal sheath does require to be earthed (as extraneous metallic part0) but only necessary at one point, and will generally be by a banjo, looking at the bolt at the top right i would say this has been done, although cant see enough to verify it
as far as i can see the work has been carried out to a very good standard !
and only requires a 3 core flex connection to the fan
which relays the problem that the fan is a timer version and requires a switched live, possibly via a pullcord or a switch mounted at a lower level
even if the timer was linked it would still need a source to turn it on
i personally would swap the fan with a va150p which has a built in pullcord and would only require a straight connection !

I'm not saying the work hasn't been carried out to a high standard. And ultimately I'm pointing things out for him to check before he connects anything. Because it is durmz who will be responsible for it if its not correct.
And if that is the bolt for the earth it still requires an earth tag. And is also required to be made of brass, or copper.
Because steel rusts corrodes etc which does not comply with 543.2.4. And as I'm sure you will know, rust does not conduct electricity.
Regardless of if it has a seperate cpc conductor the armouring still requires earthing, and as you can see the spur is looped to another supply (one cable in (supply) and one out to another spur(?))
And the earth connection must be maintained through the armouring at everypoint with an earth tag to the accessory. Yes it only needs bonding at one end IF it only fed one point and did not loop out to other supplies.
Otherwise you cannot verify that the earth on the armour is constant to the rest of the circuit, and earthing with a steel bolt through a steel enclosure is incorrect, they will require a physical connection to maintain the earth integrity the length of the swa cable
I was just advising him on how to get what he has to work the simplest way as from what he has said he isn't an electrician. So its useless us spouting the technical side of it as It might just confuse him.

no your absolutely right dude, theres not alot you cant post up in here and not get help with, theres a real large diversity in the tgtt community.
really appreciate all the help chaps, im trying to take alot of it in, im working my way through it.

yeah absolutely dude, ive done some electrics before so know obviously whats stupid and what isnt. for instance I obviously have this circuit turnt off at the distribution board! LOL its just this is more specific you know.
now then, I got a switch, sold to me as 3 pole, but is this not 2 pole?

ok to help me make sure im not being a numpty, someone check this,
woowwww thats really crap quality, sorry folks, paint doesnt exactly do hi-res, hope you can get some idea from that
That's how I'd do it with the materials you have!!

right ok will do.
alright thanks folks, should have it done by end of day, will update, having a plumbing crisis atm lol water farkin everywhere
