Couple of quick questions. Where a fuse is used in the board what do you write in the part (type) under (overcurrent device)?

What's what between the two in the section (Main Switch or Circuit Breaker) between (Current Rating) and (Fuse Rating or setting)?

Thanks.

The type for a BS 88 fuse will either be gG or mG and for a BS 1361 fuse it will be either type 1 or 2

Thanks. What is the difference between each type in the bs1361 ones?
