Im doing a job and need to install emergency lighting and a fire alarm system but the big red book says they ned to be on there own circuit. Im working on 3 phase and thinking of taking one of the phases to make a CU to feed it but then it would not be balancing the power round the 3 pheses. Also how do I get the N to each fuse box?? I have worked on 3 phase but never done a full rewire.

The fire alarm supply needs to be from the origin of the supply with an appropriate warning label 'Fire Alarm - Do Not Switch Off'.
Emergency lighting should be wired from the local lighting circuits for which they are required.

Why separate fuse boxes. Usually you'd have 3phase board with separate breakers for each circuit. Then you do not have a problem because the neutral is (well) already there.
I echo the above comments. You need some help on site, what you are attempting appears to be outside your competence zone.

The emergency lighting generally would not be on it's own circuit on it's own board.
Emergency lights should go on the same circuit as the lighting you are trying to back up.
Some more detail would be appreciated.

Mr patel said he wanted his 3 phase split up into 3 CUs and I didn't see a problem with it until I saw 1 N. This job is a right mess as some Kosovans or rusians have done the 1st fix and boarded all the ceilings and there was 100s of wires here there and all over the place but I have tested them now and it took a full week.
Is Mr Patel a competent electrician?
Are you?

Sorry, I know you need to start somewhere, but you don't seem to have the competence required to do this job for a paying customer...
Paying customer Thats a joke but ill tell him 3 single phase CUs is not the way to go and he needs a 3 phase board. All the wiring thats in for the fire alarm are the right type but im not sure if its correct as them that put the wires in don't know how to wire a 2 way light circuit right.
