When MANWEB first connected the supply to the houses on our estate back in 1982 they decided to install all properties with 60 Amp protection fuse's.Quite right. Ours said 100A but the fuse inside was 60 A which the DNO upgraded.
Earlier this year, when I asked the DNO to upgrade my protection fuse, they first offered an upgrade from the current 60 Amp to 80 Amp and explained this was a 5 minute job, as the 60 Amp fuse and the 80 Amp fuses are physical the same size and uses the same service head.
Simple switch - one out, one in !.
However, if I wanted a full upgrade to a 100 Amp fuse, then the whole service head would require replacement, because a 100 Amp fuse is physically larger in size and will not fit into a 60 - 80 Amp service head.
What I find hard to understand is this.
The main cut fuse should only be touched by the DNO and therefore it is their soul responsibility.
So, why would a main cut fuse have a 100Amp rating on the case and then a 60 amp protection fuse installed inside and then sealed with a lead safety tag ???.
Surely they SHOULD re-identify the cartridge holder with the correct fuse ratting for safety reasons alone.
