DJK what are the charecteristics of Neozed/ Diazed fuses? Are hey the same as BS88? Have a copy of the ETCI rules (1993 reprint) had a quick glance cant find any specific ref to N/D fuses. I remember Crabtree used to use this type of fuse as protection in some of there motor control gear. In industry I saw many moddifications where maintenance persons had no spare fuses. They were quite frightening.
