H i Guys!
Ive already asked for a maximum zs for a bs 88 20 amp fuse!,
but any idea about a bs 88 fuse rated at 63 amps.
I can only see one table and that suggests 5 seconds disconnection.

It comes off a bussbar to a fused isolator and the to a ventilation heater. Am i right in saying 5 seconds is too high, or because it comes from the bussbar to a fused isolator it is classed as a distribution circuit.
Thanks anyway
