13.1.1 Mains fuses
Stop!
An additional cable protection is required when using fuses of the operating class
aR (partial characteristic) as phase fuses.
If the fuses of the operating class gR also protect the cable, the cable cross-
sections must be dimensioned according to the fuse. Otherwise, provide a
separate cable protection!
