wiring question

That is one end

the outer insulation is out of the box and u could have kept the wires shorter and in line. hmmm don't show me any more

thanks for the constructive critcisim i am learning

 

[123hotchef]

i did push the outer insulation into the box before i put the lids on and cable tied the cables to the ceiling to hold them tight

You also seem to have a data cable running through the left box, there should be separation from mains...

Current standards clearly define the separation between power and data cables. For instance, the minimum separation distance between unscreened power and unscreened UTP cable is 200 mm. This is reduced to 50 mm for screened data cable and to just 30 mm if the power cable is screened. Electro-magnetic interference from power cables can reduce the performance of data cables, particularly speed of data transmission.

Are those crimps suitable for mains wiring? They look like automotive types to me.

well they were not seperated before i started and there were no problems

Just use this instead?

Also not good to mix mains & phone\data cable even though 16-6-6-1 now allows it, If I read it correctly

 

[brightspark]

don't get a lot of choice when your using twin compartment dado trunking round a computer room or offices . data and sockets

BS There is usually a partition\separator, when I was an apprentice my boss would have handed me my cards if I had left a roof in that state.
A lot of sites now want things laid out logically to aid fault finding

 

[123hotchef]

i have seen the trunking with a partition in it

Exactly i don't think the separation distance in the reg's are realistic or appropriate to modern data connections and error handling.
There must be thousands of miles of data cabal sitting on top of power without any problems.

I wouldn't be happy with mains and signal joined with crimps in the same box, especially 1.5mm crimps on a bit of tooth floss size cat 5 big risk of wire pulling out and sticking into a live terminal.


EDIT :- are the crimps all the same size?

yep thus far anyway might need bigger ones for the 6mm2 cable, i did fold the cat5 back on itself to make it thicker reducing the chace of it pulling out

look at post above twin compartment data in one power in other

I must say I do like the method employed for fixing the copper pipe...

I know its not what a time served plumber would be happy to see but, i would sort of be OK ish with it. I am guessing it will be positioned when the insulation goes on. Anyway floods are easier to deal with than fires.

Perhaps the leak will put out the electrical fire
