Power Distribution: Understanding Your Fuse Box

Your fuse box is the key to learning and understanding how power is distributed through your residence. Whether the fuse box has already been organized and power distribution made by the builder or if you are wiring your residence yourself, you should know how a fuse box works so that power is equally distributed and distributed as needed.

Fuse Box Organization

A fuse box is organized according to how power is distributed through the residence. Each fuse directs energy to a specific area, appliance or utility so that it will be able to perform its function. However, a fuse also regulates the amount of energy to prevent what it directs power to from becoming overheated and causing a fire. This is why, should an item be on the verge of becoming over taxed by using too much electricity, the fuse switch will flip into the off position and disconnect the flow of energy.

Individual fuses in a box are identified and separated. Some appliances may have more than one fuse due to its power needs. These switches work together, meaning that they both will switch off and need to be switched on in the event of too much electricity flooding through the wires.

The fuse for an area might be tied to a fuse for a particular appliance. For example, electric outlets in the kitchen will be attached to the same fuse as the refrigerator. To work on overhead lamp you will need to turn off the fuse for the refrigerator, meaning that the refrigerator will not function during the maintenance on the lamp.

A Fuse Switching Off

A fuse can be switched off either manually or automatically. An automatic switch off occurs when too much energy is flowing through the wires to a particular item and that energy flow is dangerous. In such a case, the fuse will automatically switch off, ending the flow of power and shutting down the utility or appliance. Restarting the flow of energy requires you to manually flip the switch so that it will once again permit energy to flow.

Manually turning a fuse off is most common when an appliance or utility is not functioning properly or needs to be turned off for maintenance. When installing overhead lighting or a new appliance, for example, it is best to disconnect the flow of electricity to prevent electrocution.

Switching a Fuse On

No matter what, turning a fuse on must be done manually. The reason for this is to call attention to the fact that something happened that made shutting off the flow of electricity necessary. By not working and requiring manual effort to turn the switch on, the resident will be notified that something needs to be looked at to prevent misuse, fire or other damage.

Switching a fuse is simple; it just requires that you push its black bar to the other side. Do not worry about being unable to tell which direction the fuse must go because if it is turned off it will be in the opposite direction of the other fuses.
