Consumer Unit Questions

[ta-electrical]

Hi, i've got a few questions regarding consumer unit connections;

My first question: On a split load consumer unit does every circuit need to be protected by RCD e.g. lights ?

Second question: If a high integrity consumer unit has two unprotected circuits next to the main switch, do they have to have RCBO or would MCB protection be sufficient enough to meet the 17th edition wiring regulations?

Third question: A 6mm SWA cable going to a shed to a small consumer unit with RCD - supplying a ring main and lights - will the cable need 32amp RCBO on the main consumer unit in the house or just 32amp MCB protection?

Thanks in advance.
