!±8± Electrical Fuses 101

Most people who are not familiar with electricity don't know that electrical fuses protect electrical circuits from over amperage, not over voltage.

Amps or amperage is the flow, or amount of electricity. Voltage has to do with the force the electricity current flows. A example of this would be a fire hose with a nozzle delivers high pressure (voltage), but also low volume (amperage). The fire hydrant may have huge volume (amperage), but will only push the water a few feet due to it's low pressure (voltage). So when you multiply amps x volts you get the wattage.

Every electrical circuit whether rated to handle a large shop machine or motor, is setup to handle specific amperage. Your wiring is also only rated to handle a specified amount of amperage, if you try running too many amps through the wires, they'll overheat and melt. The purpose of a electrical fuse or circuit breaker is to trip or blow before damage is done to the machine, electrical product, or wiring.

Standard Home Fuses:
New homes have circuit breakers but many older homes have a fuse box that which fuses screw into sockets similar to light bulb sockets. There are two types of bases for sockets, the Edison Base which are Type T Fuses and the Rejection Base which are Type S Fuses. The Edison Type T base fuse screws directly into the socket in the fuse box. The Rejection Base Type S fuse actually screws into a adapter base, which locks the fuse into the fuse box. Each of the Type S fuses has a different size adapter base for each different amperage rating fuse. With the different types of fuse bases you are unable to put a larger amp rated fuse into a smaller amp circuit.

Many older homes also use a Edison Type W fuse which are becoming obsolete. These Type W fuses are fast-acting, and have no time delay element. The Type W is designed for general lighting and power circuits that do not run electrical motors. A electric motor draws more current when it starts up and will blow the Type W fuse.

The medium duty time delay fuses are now a commonly used plug fuses for homes, these are called the "TL" and "SL" fuses. The "TL" fuse is a Edison fuse and the "SL" fuses use the rejection base. These fuses are used where power surges can occur, such as a garbage disposal.

When larger motors are used in circuits or motors that cycle on and off many times use "S" and "T" fuses. These fuses are heavy duty time delay fuses, the differences are the "S" fuse uses rejection socket bases, and the "T" fuse has a Edison base.

The last type of home fuse is a retrofit circuit breaker fuse are known as Minibreakers. These fuses convert a socket fuse into a push button circuit breaker, that pops out when overloaded. To reset these breakers all you do is press the circuit breaker button back into position and your up and running.

Moving to Australia - What You Should Know

!±8± Moving to Australia - What You Should Know

You would think that an American moving to Australia would have a pretty easy time adapting to the new environment down under. After all, Australia is a western society with a great deal of tolerance for other cultures. The English-Irish roots means there should be no language barriers other than having to learn a few slang words here and there. Theoretically, you are correct. Practically, there are some things you should know of before moving to Australia.

In Australia, they drive on the other side of the road. Dreaming about driving your new sports car down the long empty roads of the great Australian Outback? Forget about it. In Australia they drive on the left side of the road, therefore cars are built with steering wheels on the right-hand side. You could have the car converted into a right-hand drive vehicle, but the expense is not always justified. In addition, you need to adjust your driving habits and always remember to look the right way when making a turn or crossing an intersection. Unfortunately, a small number of tourists are killed in car accidents annually because they looked the wrong way while driving. Pedestrians need to be careful just as well. Electricity in Australia works on the European system of 220 volts and not the US system of 110 volts. This means if you were thinking on shipping your appliances to Australia, you better think again, for they will not work down under. Power converters could help, but take into consideration these points: You will need a converter for every single appliance that runs on the 110 volt US electric system. Converters are not particularly cheap. Converters burn out easily. Even though you may use a converter, there still will be a difference in electricity cycles, which means the clock and timer of the appliance will always be off by a few minutes.Tuition for university in Australia is very costly. Although there is a student loan program called the HECS, you would still need to qualify. HECS can arrange a delay in paying university tuition fees until graduation. Then the fee a docked from the salary as tax once employed. But in order to enroll in the more desired majors such as law, engineering, and medicine, students need to score highly on HSC exams. Otherwise, only other disciplines will be open for the HECS loan.All other issues aside, moving to Australia has turned out to be the most positive life choice for thousands of expats from all over the world. Sunny weather, laid back lifestyle, and an opportunistic economy all combine together to produce an living environment worth moving down under for.
