What is a device that is used to protect the wiring cables in a building?

Wire protection devices come in a range of forms, sizes, and current ratings. The most frequent type of protective device is a fuse. A fuse is installed in an electrical circuit so that when the current flow exceeds the fuse's rating, it "blows" or "blossoms." This leaves the remainder of the circuit intact so that you can continue to use other components on the circuit.

The next common type of wire protection device is a circuit breaker. Like a fuse, the purpose of a circuit breaker is to protect wires from damage caused by excessive current flow. However, a circuit breaker will automatically shut off the power to an entire section of wires when one or more circuits within that section exceed their current limit. Circuit breakers are useful for preventing accidental electrocution. They can also be programmed to turn off the power at a specific time per day or after being closed for a certain period of time. Some circuit breakers have auto-recovery features that will restart if there is no contact with a person or object for a certain amount of time.

Other types of wire protection devices include: metal oxide varistors, spark gaps, and wavelets. Metal oxide varistors work by passing only a portion of the current through them; the rest goes into heating up the device, which causes it to glow red and emit oxygen gas. This protects the wiring from burning down due to high currents.

What is a fuse wire and how is it useful?

A fuse is a piece of wire with an extremely low melting point that serves as a safety device. When a strong current is passed across the circuit, it melts and breaks when the temperature rises above its melting point. It is used to prevent short circuiting and so safeguard electric appliances from harm. Fuses can be replaced by a circuit breaker but for some applications this is not an option.

Fuse wires are wires within an electrical system that control what voltage gets to a particular point. The term "fuse" comes from the fact that these wires were originally made of thin strips of paper called fusibles. Today's fuses are usually made of glass or ceramic and contain strands of metal inside a casing. A live wire goes into one end of the fuse, while a neutral wire goes into the other. If the fuse blows, which means if there is a open circuit, then the power is off to that part of the circuit. You should never try to repair a fuse yourself; call a professional for service or replacement.

The type of fuse used in a circuit depends on how much current is being drawn. If you're using small appliances such as lamps, fans, and heaters, then a general purpose fuse will work fine. For larger appliances like stoves and dryers, however, a household or appliance plug-in cord with built-in fuse is recommended. These cords have several pairs of wires inside them, with each pair serving a different purpose.
