I am after a bit of advice for a job I am quoting.
The current set up is 2 workshops next to each other. Both units are fed by 1 2x5x5 split load board. Each workshop has a socket Circuit, couple of heaters and a lighting circuit. No issues there.
The landlord is now renting each workshop out to seperate businesses and wants to bill them seperatly. So my plan is for unit 1 to have the current split load board. Off this (non RCD) a submain circuit for a new RCBO board for unit 2 via a MID Approved Check Meter which can then be billed as necessary.
My issue here is the board is fed in 16mm T&E cable buried less than 50mm in the wall. So needs an upfront RCD. I'm not keen on 2 workshops running off 1 30mA RCD thats in accessible. A 100mA Type S crossed my mind but obviously I need 30mA to protect the submain.
Is everyone in agreement that a new submain with a upfront Wylex 80A Switch fuse is the best Option? This will probably go down like a sack of poop due to costs but I can't see any way around it?
