Frequently Asked Questions:

Q. What does fuse capacity mean?

A. Fuse capacity, also known as fuse rating, signifies the amount of current required to trigger the fuse's breaking mechanism. When a fuse blows, it interrupts the electrical power flow in a circuit. Typically indicated on the fuse's exterior, the rating is usually denoted in ampere. Amps serve as the unit of measurement for electrical current and dictate the magnitude of current that can pass through the fuse before it activates and disconnects the circuit.

Q. Is resetting a fuse safe?

A. Before resetting a circuit breaker, it's essential to identify the underlying cause of the trip. It is safe to reset a breaker solely when it's confirmed that the circuit was overloaded. Repeatedly resetting a breaker without addressing the root issue could lead to hazardous outcomes, such as an arc flash or even a fire.

Q. How to determine which fuse needs replacement?

A. Inspect the fuse box and examine the glass enclosures holding the fuses. If you observe a visibly broken fuse or detect metallic residue on the glass due to a blown fuse, that specific fuse requires replacement. Remember to switch off the power before replacing a fuse for safety reasons.

Q. Which instrument is used to examine a fuse's functionality?

A. To ascertain if a fuse is blown, a multimeter is required. Once properly configured, a multimeter can measure the resistance of the fuse element.
