Rewiring upstairs lighting circuit

Ahh, I see your point!

Just explain to the customer the different options and the advantages/disadvantage of doing it that way- and then its up to them- you can only give them your opinion

I would probably put RCD FCU in as it's easiest - Have you checked to see if you can replace the MCb with RCBO?

I did think about that bit not sure of the compatability due to the age of the existing board. However before I start the job ill get a look in at what make the board is and try and find one that fits. If that fails the the RCD fcu is the next option.

Yes I'll do that, after all they're the ones paying for it!

If the 13A fuse is in the RCD FCU will there not be a diversity issue as the new RCD FCU will be fed by the current 6A upstairs MCB?

May have mis-read above so ignore me if I have

EVEN WITH A 5a FUSE, YOU WILL GET DISCRIMINATION PROBLEMS AS THE 6a mcb WILL MOST LIKELY GO FIRST.

Yeah good point Telectrix, how should the OP get round that issue then?

 

[telectrix]

i'd not bother. stick a 13A fuse in as the cable is adequately protected by the 6A MCB

And if your planning of re wiring the whole circuit anyway (new circuit from db) bonding will need to be in place anyways and to issue a eic regardless of upgraded the db or not.￾
