just moved house, looking at the consumer unit - wylex split load 80A rcd
100A isolator looks newish. Says on the front 'for all circuits total load not to exceed switch rating', in the unit there are the following mcbs
non rcd
40A cooker radial
16A heating/boiler radial
6A upstairs lighting
6A downstairs lighting
6A Smoke alarms
rcd
32A west ring
32A east ring
32A garage ring - thought I'd derate to 16 since can only use dust collector + one tool at a time
32A kitchen ring - fixed appliances (washing mc, tumble dryer, dishwasher waste disposal unit
6A garage/external lighting
total 206A ummm Diversity - in that case why the label
Had a look at screwfix, found the consumer unit with preinstalled mcb's
1x40,2x16, 4x32, 3x6 total 216A
do they do 200a isolators then?? if not why so many mcbs.
I'm not particularly worried since at the moment incoming 16mm2 tails + 60A main fuse hopefully soon to be uprated.
Largest supply i've heard about is 125A new builds so do you get 125A isolators or do you put 2 isolators in one box or what.
Any comments on the distribution of mcbs above and why the label, anybody here total mcb's less that isolator value
