    Fuse replacement 110V 5A to replace 220V 5A ?

    Hello All...have tried to google also but still cant find solid conclusion. Please help me understand, the original fuse is 220V 5A. Is it ok if I replace with 110V 5A? thanks

    Hi,

    No.
    --> Use a fuse with at least 220V voltage rating.

    Hi,

    If a bungee rope is rated for 110 pounds .. would you recommend your 220 pounds friend to use it?

    Hi,

    fuse voltage ratings is a good term to search with.

    It's well-explained in the following document, page 2 and section: Voltage Rating-Fuses

    Overcurrents and Voltage Ratings

    "The voltage rating of a fuse is a function of its capability to open a circuit under an overcurrent condition. Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced. If a fuse is used with a voltage rating lower than the circuit voltage, arc suppression will be impaired and, under some overcurrent conditions, the fuse may not clear the overcurrent safely."

    Bungees aside - when a fuse breaks it is because the current through it exceeded its rating. The current causes heating in the fuse wire regardless of the voltage - BUT consider what happens as the wire breaks. A higher voltage rated fuse is designed so the gap in the wire cannot arc and thereby allow some current to flow. Higher voltage rates fuses will open a wider gap or have a different filling that can resist more voltage than lower rated ones.
