Very old fuseboard change

[moosey86]

Ok then,

Got a 15 way 3phase board (re-wirable) to re-locate and change to a new one. It's a really old BILL one from years back. Its a weekends work for 2 blokes. Just a couple of things I wanna clear up.... :-

1. Im going to put RCBO's in for anything that has a socket outlet on it, 3phase or single phase. I'm pretty sure it doesnt need to be loaded full of RCBO's for every circuit??

2. What is the best way of sequencing the neutrals respective of the correct circuits i.e. what is the best way to find out which one is which without tracing them and not blowing up machines.

Your help will be muchly appreciated

Cheers

don't think 3-phase rcbos are available -usually rcd/mcb afaik

Sorry, should have explained myself.... change the 3phase sockets to ones with an incorperated RCD.

If its existing though do i need to do this?

It realy depends on the installation method of the other circuits and also what the other circuits are supplying , one thing i would do before you change the board is to inspect the installations , you could open a large can of worms with a board that size and age ,

Imo Nick speaks great sence Can of worms before DB change of this size as you never know who had done what and what has been swapped around a right good PIR to identify circuits
