Hi
Ive read a few discussions on the topic but what setup would you recommend for replacing a DB on a domestic TT system?
I've moved house and need to get the meter changed ready for the car charger, I need to upgrade the severely dated DB at the same time.
Existing is a multi9 13 way RCD main switch DB, one of those circuits is a sub main to the garage which I'm intending on adding a car charger to at some point, realistically the only option I see is a 16 way DB, I was looking at this

The intention was to use RCBO's for the circuits which I think would allow me to keep the main switch, I think my next question is on the sub main to the garage, if this is for example a 50A 30mA RCBO in the main DB would I need to install RCD protection in the sub main or should that not be a RCBO and a separate earth ROD installed for the garage, this would prevent a fault tripping a RCD upstream.
Thanks
