Thanks for the reply,The incoming fuse could be 100A, but most often they are 80A - the holder in all cases is rated 100A and the picture you posted only shows the standard fuse holder rating, there is nothing in the photo to confirm the actual fuse size.
So the question of actual load remains, in order to exceed 80A essentially the shower, all the Hobs and around 10A of rfc load would all have to be on together, if this is a typical house, I would think this would be very unlikely.
If it is someone running a home cooking business, with a few fan heaters around the place etc, and kids taking long showers etc; then they could be in excess of 80A.
I don't subscribe to the old style estimates for max demand in terms of lighting and ring finals, as we now distribute the loads over several circuits, not because of load, but for safety/security of supply.
The modern model of multiple circuits doesn't mean a corresponding increase in load, merely a distributed 'same' load
In reply to a previous post the CU is a split load with a 100a isolator one half is protected by the rcd 3 x32 and now 2x 40 and the other half is 2x6a -lights 1x16a -boiler and 1x6 a smoke detectors
The premise is a flat leased on a serviced apartment type thing anything from 1 night to a year and more.
Im the maintenance man from Aberdeen (ex sparky) and have been down correcting all the c2's that a company found whilst they were carrying out EICR's for the building (25 flats)
What I have found strange though is that all 25 flats are identical yet not all of them have been flagged for having an mcb rated too low also whoever did the tests missed at least one FI,(didnt get all the work done I tested positive...whilst in weegie land so came home) one of the rings in the bedrooms is missing a leg and this is the second EICR done on these flats.
