    Question on maximum demand (load)

    Hi, the maximum demand (load) in a property is as follows: (4x32+4x6)0.40 = 60.8 amps and the main fuse rating is 60 amps. Does this comply, taking tolerance into consideration? What is the tolerance in this kind of situation? Should I ask DNO to upgrade the fuse and the tails? Many thanks!
