In my attempt to ask a billion questions on this board!!!...
Here's the next corker thats puzzling me.
I'm attempting to work out maximum demand in my house using OSG guidelines
My lighting circuits draw a maximum of 975W so 66% of that gives 3.3A
Fixed alarm circuit drawing a maximum of 3A
Cooker (not connected to a cooker at present so i've just used the basic figures) 10A + 5A for the associated socket outlet.
Final ring circuits 3 each drawing 32A (So thats 32 + 12.8 + 12.8)
Plus my shower circuit 7.5k (Max draw 32.6A)
Anyway to cut to the chase
By my calculations that gives 111.5 A
And i've got a 100A main distributors fuse (As well as the main switch)
Does the maximum demand need to be under the rating of the fuse or do you record the value regardless?
Or (this is more likely) am i getting my figures wrong?
Hope someone can help
Thanks
