My house crabtree starbreaker 16 way with RCBO protection on each circuit ,as for telex question ,in my area the standard fuse on the DNO side was 60 amp until recently although almost every cut out was labled as 100 amp , now all cut outs that are upgraded have an 80 amp fuse ,theoretically 16 mm tails would be adequate ,but if you take into account regulation 514.3 the minimum meter tails should be 25mm , now the funny part regulation 434.3 ,where the metr tails are protected against fault current by the distributors cut out the method of installation,maximum length and minimum cross sectional area must comply with the requirments of the distributor , yes so why do we find 2.5 mm 6mm connecting CDU's up to a sealed meter eh
