80A BS1361 Time Current Curve

Farmboy over 5 years ago

Hi all

Does anyone have a copy of the graph / curve please, either on its own or perhaps along with a 60A curve?

Thanks

the curves in the second link don't seem to match those in the first

Not impossible - manufacturer's data often shows "better" characteristics than the generic data from the fuse's standard or BS 7671 charts. You're free to use manufacturer's data if you want, but it really should be from the manufacturer of the particular fuse you're considering..

Is this for an EICR or similar? It's just that BS 1361 is now defunct - replaced by BS 88-3 (and 60A by 63A) - and with slightly different time/current characteristics too I suspect.

Looking at adding a socket in a domestic installation that has an 80 1361 main fuse. I'm replacing the 10mm2 earthing conductor with 16mm2 but just for giggles thought I'd give the adiabatic a spin.
