Can anyone help here.
My client has listed fuse types as 60269-1. I understand that a 0269 is basically a BS88 but what I can't find is Zs values for type 1. The regs show values for BS88-2 and so does the pro-cert app?
Yes thanks I spoke to Lawson fuses and they said a 60269-1 is available and is usually used in lamp post cut-outs. They said the ZS values are the same as 60269-2. So as you mentioned a 60269 is a BS88 so I can use the Zs values hat are in regs, as 60269-2 is a BS88-2. Cheers
