Safety Electrical Devices

1. Fuse- a fuse can cause the main electric circuit in a house to open and cause a brown- out.

- The fuse is made up of a strip of metal that melts easily when there is overloading or over heating. It is placed on the main switch to prevent the outbreak of a fire.- When the fuse blows, it is a sign that there is something wrong in the circuit.

2. Plug- a plug is used for each household appliance. Thus allows electricity to flow freely when plugged on. - After use, the plug should be pulled out to save electricity.- Plugs enable people to use electricity in their homes, offices, schools and any place where electric power is needed.

3. Electric meter- Every month, a personnel from the power company like ISECO, reads the electric meter. - The electric meter measures the

electrical consumption at a given time.

- It tells how many kilowatt hour have been used by a household.

4. Switch- The switch helps you to easily turn on and turn off the electric circuit without any danger.- It opens and closes a circuit.- It is covered by a plastic to

prevent touching the electrical wire in a circuit.

5. Transformer- It is a device used to control the voltage of electricity.- A transformer can either raise or

lower the voltage of electricity.- Imported appliances from the

United States and other European countries have 110 volts. A step up transformer is needed to make these appliances work.
