Hello there,
I have just started a job that used to be 6 offices which are now being turned into 6 flats. All flats located on the 1st floor. At this moment the meters and switch gear for all 6 flats is on the ground floor in the electrical cupboard. The 25mm tails for each supply go from the meter and terminate into a 60amp switch fuse. From the switch fuse a 16mm twin and earth cable is running up a riser into each respective consumer unit. Each flat will have a 9kw boiler 45amp MCB, 6kw cooker 32amp, sockets, lights, smoke alarm. So I have a few questions I would be very greatful if someone could help me with.

1.) Is the 16mm twin and earth supplying each flat sufficient for the circuit loads I have stated above? boiler 45A, cooker 32A, sockets 32A x2, lights 6A, smoke 6A?
2.) Is the 60amp switch sufficient for this supply or will I need to change it to a 80amp switch fuse?
3.) Is the 16mm twin and earth protected enough going to each flat or should I strip the all out and run Steel Wired Armoured?

Please help,
Thank you.
