Q:

What is the function of a fuse?

A:

A fuse prevents an electrical object from receiving too much current. In the event too much electricity is received by an electrical component, the fuse is designed to melt and separate.

There are several different types of fuses. The most common in the automotive industry is called a cartridge fuse. Cartridge fuses are held in place by spring clips and are easy to replace when necessary.

The most common fuse used in homes is a circuit breaker. Circuit breakers are switches that open up to stop current in the event of an overload. They can be closed by the flip of a switch. Circuit breakers are common in homes, businesses and industrial services.

  • Q:

    How do you wire a fuse block?

    A:

    A fuse box has a sole purpose of offering protection from power surges and fires. The fuse in the fuse box blows when there is an overage of power in the system caused by a power surge. This protects the electrical device receiving power from the fuse box because the fuse box stops the surge and doesn't allow it to reach the device. Electrical experience is recommended when wiring a fuse box.

    A:

    The About.com Home section explains that a circuit breaker trips, or fuses blow, because of either an electrical overload on the circuit or a wiring problem. Overloads are more common and easier to fix than wiring problems, which can be more complicated.
