3. Fuse Selection

Question.6

Tony uses a 250VAC cartridge fuse in a 48V DC battery system because the voltage is lower than 250V.
Is this selection technically safe?

Yes — 48V is lower than 250V, so it is safe
Yes — current rating matters more than voltage type
Not necessarily — DC fault interruption is harder than AC
No — AC fuses cannot carry DC current
