switch-fuse and service-fuse discrimination
Even an ordinary BS1361 fuse will carry its rated current indefinately,
will sustain a 30% overload for an hour, will trip in one second on a
3 times overload and will trip 'instantaneously' only on a ten times
overload.
Service fuses have an even more forgiving characteristic than this so
OP has little to worry about. Except his electricity bill.
