A live wire is always linked to a fuse. If the fuse wire is attached to the neutral wire rather than the live wire, the appliance remains connected to the live wire and the current delivered is not disturbed due to overloading. The difference lies in how the wiring is completed on the premises. For example, if there are two separate circuits feeding into a single breaker box, one circuit may be used to supply power to one set of lights while the other circuit provides power to another set of lights. In this case, both sets of lights would have a live wire connected to them. However, only one set of lights would have their neutral wire connected to the breaker box - the other set of lights would have their neutral wire left open. Any device that uses electricity like a light bulb would need to be wired appropriately in order to avoid being damaged by an electrical surge.
In most cases, you will see instructions with pictures that show you exactly where to connect the black and white wires together with the fuse holder or breaker panel. Follow these directions carefully. If you are not sure which wire is which, just ask someone who knows their way around a house if you can't figure it out. Chances are they will be able to help you out.
Make sure that you only connect one black wire to one white wire at a time.
The fuse wire is always connected to the live wire of the electric circuit because if the fuse is somehow connected to the neutral wire in the circuit, current will stop flowing in the circuit when the fuse burns due to the excessive flow of electric current when the fuse burns, but the appliance will still be connected to the high...
The fuse wire is always linked to the circuit's live wire because if the fuse is placed on the neutral wire, when the fuse burns, current stops flowing in the circuit due to excessive current flow, but the appliance remains connected to the high potential point of the supply through the live wire. This could cause serious injury or death.
If you're lucky enough that your local utility company uses fiber optics for their power lines, then you might be able to see a faint blue tint to the wires when they enter your home. This is normal and it doesn't mean that you have any kind of damage to your wiring. The blue color comes from chemicals used to prevent oxidation and deterioration of the cable insulation. These colors should never be removed or altered in any way. Doing so can lead to electrical problems down the road.
In most cases, though, you won't be able to see the fuse box or circuit breakers used by your local utility company. This is fine, however; they are not responsible for any damages that may occur due to an improperly wired house circuit. If you suspect that there is an issue with your wiring, have your electrician check things out before you call them in case you need to charge them for additional work.
The fuse comprises a bit of wire that readily melts. If the current flowing through the fuse is too high, the wire warms up and melts, breaking the circuit. Fuses are available in various sizes for different current loads. Outlets may have separate fuses for ground wires, line wires, and neutral wires. Before replacing any appliance or fixture battery, switch, or circuit breaker, check for power at these other locations to make sure there are no broken wires or bad connections before repairing the problem.
Electricity flows through conductors called lines. These lines can be part of a local network (called wiring) or they can be exposed outside walls or roofs (called conduit). Electricity travels from place to place through people and equipment as long as there are things to transmit it. For example, electricity flows through a light bulb because lamps are designed to let some of it go into their filament material. The rest of the voltage continues across the socket outlet until it finds something that will allow it out into the world again. Sockets are made specifically to protect people from dangerous levels of electricity, so sockets should be treated with care. It's best not to insert anything else into a socket except for a pronged plug!
Sockets are also used to connect appliances directly to the wall outlet.
When it does so, it breaks the circuit, which prevents further current from flowing through it.
A low-value resistor has the same effect as a fuse. It will break the connection if the current through it exceeds some value. But it can also burn out your hand easily if you get close to it! Fuses are safer in this respect. They have enough resistance that only very high currents will cause them to blow.
The purpose of a fuse is to protect people from getting a shock if they touch one end of it while an electric device is connected to the other. A fuse is designed to melt at about its normal operating temperature (about 120 degrees Celsius or 248 degrees Fahrenheit), breaking the connection between the two ends of it. This prevents anyone who might be near enough to feel the heat of the fuse itself getting hurt. Fuses should not be used as replacements for circuit breakers. Circuit breakers are designed to cut off power to an entire section of a house in the event of an electrical fault. Fuses are more suitable for cutting off just one appliance or group of appliances from a circuit.
