Understanding Fuses Within Electrical Components
There is a lot to learn about the various electrical components that are used throughout residential and commercial buildings. Many older homes and businesses use wiring and electrical systems that require the use of fuses. The one thing to remember when it comes to fuse systems is that you never want to use a fuse that has an amperage rating that is higher than what is specified for the system. To test fuse continuity you will want to use a multi tester. Take the multi tester and press one end to the center contact while the other one is pressed to the screw shell.
It is important to understand the variety of fuses available and to be able to identify them in case you ever need to replace one. Fuses are used in automobiles, appliances, circuit breakers and a variety of other electrical components around both residential and commercial settings.
The most common type of fuse is a low voltage fuse. You will see low voltage fuses used in many electronic appliances and entertainment gadgets. This type of fuse is available in ratings up to twenty amperes. A fuse of this type can signal a short circuit in the wiring system or a system overload.
Standard plug fuses are the type of fuses used most often in service panels. Most often standard plug fuses are used to power small appliances and basic lighting fixtures. You will find standard plug fuses in amperes ratings of fifteen, twenty and thirty. This is dependent upon the gauge of the wire that is found in the circuit. As with a low voltage fuse, standard plug fuses are used t signal a short in the system as well as an overloaded circuit.
Another common fuse used in residential service panels is a time delay fuse. Similar to a standard plug fuse, time delay fuses come in amperes with ratings of fifteen, twenty and thirty. The unique quality of time delay fuses is that they can withstand a small power surge, such as a startup of a motor. They are the fuses used to signal short circuits, circuits that are overloaded and sustained circuits.
A type-s fuse is used for powering up small light fixtures and small appliances. There is only a slight difference between type-s fuses and the standard plug fuse is that the type-s fuse can guard against the accidental installation of a fuse that has an amperage rating to high for the circuit. This type of fuse fits an adapter that screws into a service panel. The adapter only fits into type-s fuses with matching amperage.
The ferrule type cartridge is used in fuse type service panels. They are used to power major appliances and are available in ratings up to sixty amperes that suit the gauge of wire in the circuit. The fuse can withstand a small surge, can signal a circuit that has become overloaded, a short or sustained circuit.
The last type of fuse to discuss is the knife blade cartridge fuse. This is the type of fuse used when more than sixty amperes are needed to protect the electrical system of homes. The knife blade cartridge fuse can withstand momentary power surges.
