Discuss BS 1361 50A ZS in the UK Electrical Forum area at ElectriciansForums.net
Thanks I will do just thatwork it out. if the current required to blow the fuse in the required time is, say, 5In, then max. Zs = V/ 5In.
Use the 5A value and divide it by 10.
why 0.1sec? generally, anything over 32A needs to blow in 5 secs. to comply with BS7671.
We could do lottery pick - easier than finding that football ...
My pick is 0.927 Ohms for 5 sec on BS882 50A, from 248A guesstimate.
Don't forget Cmin
Oops, forgot that ... my guess now drops to 0.881 OhmsDon't forget Cmin
