60 AMP FUSE

[echoes]

This balancing debate - surely there's never often that much load to balance since 95% of the time the current demand is probably well less than 5A for the entire property. Balancing such a low duty cycle would be futile?

I had a cut-out changed some years ago (because it was broken), and the nice contractor the DNO sent round saw the old 60A fuse and said "let's give you a nice 100A one" for no particular reason and he put a new 16mm earth strap on. Very nice chap.

OOI, when upgrading a main fuse, is it a case of, "this week, the supply cable will mostly have a capacity of 100A" by the DNOs, or are they installed overspecced in the first place?

Obviously when installing wiring for a new housing estate, they will generally try to evenly distribute the phases across the houses. (as this is common sense and good practice)

And you could also say that if it was an all electric estate in the period leading upto dinner time, that the load on each of the phases would generally increase as ovens were switched on.

And maybe if they all had night storage heaters it would be an even load at night.


But just because one old house has a massive new shower installed which maybe used at the same time as the oven for 15 mins a day, you can't attempt to perfectly ballance the load across the phases.
