Thanks to all who helped along the way (here and elsewhere), my shed electrics had the big switch-on last night and all seems OK. One final question, if I may; the cable to the shed goes to a 'garage CU' with one 16A and one 6A MCB. The cable from kitchen CU to shed is 6mm T+E (inside) and 4x2.5mm SWA with cores doubled-up to 2x5mm (outside).
I used an unused slot in the Wylex kitchen CU and replaced the wired fuseholder with a Wylex 32A plug-in MCB. This now leaves the kitchen CU with 1x5A, 1x15A and 1x30A wired fuses, 1x32A MCB and the cooker fuse (45A? can't remember, will look tonight). The CU has a 'max 80A' sticker on it. Could someone please show me how to do the diversity calc to check all is still OK? Electric fan oven, gas hob.
Yes, I know I should have had that worked out before I started ...
