Carrying out an inspection on a victorian style Multiple occupancy house split into 4 flats. Each flat is wired in 10mm2 bare pyro clipped direct with and estimated draw of 30A. max run approx 35m. Each flat is protected at intake source Ryefield by a 100A 3036 porcelain fuse.
I have classed this a C2 as i am sure the cable under these conditions needs to be 25mm2 and not 10mm2 or the 3036 downrated to 60A to coincide with the existing 10mm2. Can anybody confirm this. I have performed a cable calc but would appreciate a second opinion.
Thanx.
 
Dont have any reference books near by, but your 10mm MICC will easily handle 80A..but.....depends on run, installation method etc...
Great cable in its day, shame we dont use it more often
