every safety equipment having have some safety factor and fusing factor
i.e.,
every fuse having fusing factor it is 1.2 % of rated current
if u connect a 24 amp fuse wire it will break up load is 29 amps
there fore the answer is D

Practically speaking the fuse rate must always be less than the rated load rate. Then only it could safe it against over current.

Fuse will be made -depends upon the rated current of a circuit.

The current shud not exceed 24A, if a fuse 24A fuse s used it ll fuse at 24A nd it ll not let the current exceed 24A right? So isn t de answer right?

Yes, answer is 24A. If current flow exceeds 24A then fuse works and breaks up the circuit, till then circuit is safe.

According to electrical code 80% shall be used in protecting the branch circuit, the circuit has not exceeding 24 A therefore I choose 20 A not a 24 A. Having a 24 A into not exceeding means that circuit may less or more 23 A,

Fuse is depend how many amp load in circuit.

Please help me to know the exact answer. On what basis the value of the fuse is calculated?
V.ganapathy sundaram said:

The fuse value should be 1, 2, 3, 4, and 5 ohms further it should be incremented by 5's so after 5 ohm fuse we should use 10, 15, 20, 25, . So the answer is 25. (because the fuse value should be above the current value).
