The fuse will blow out sometimes if you allow a bit of metal from a lamp shade to cavort too intimately with the excitable parts of your incandescent bulb; then the wire gets overloaded and the tin or lead conductor on the fuse melts and prevents the greater current doing any damage. It’s simple, isn’t it? The fuses come in convenient shape. Sometimes it is wise to use a rubber glove when putting them in. We have seen a sparking do a bit of burning. Electricity is not dangerous when properly employed. It is dangerous when you use it wrongly. If you put your hand under a boiling hot stream of water you will get burnt. If you put your hand on a red hot stove you will get burnt; if you burn a fire in a wooden box you will have more fire than you bargained for; if you inhale gas you will die. Such is the case with electricity, which is a most controllable force if you are not ignorant as to how to use it. However, if you will put a hot curling iron on your table without turning off your current you will have a cozy little fire start up; so you would if you laid down a cigaret without putting it out. Most accidents occur simply because of such ridiculous carelessness. Mr. A. M. Grant of the Manhattan Electrical Supply Company said a wise thing in reference to this subject: “Before connecting any appliance to your lamp socket turn out the light in your bulb; then you know that your current is off. Never attach anything to anything electrical until the current is off and never go away and leave an appliance with the electricity turned on.” More specifically, in using any electric appliance non-continuously, shut off the current immediately upon stopping. Do not only pull out the plug but turn off the electricity. In using the flat-iron detach the plug at the iron as well as turn off the current from the socket. Remove the iron from the goods and detach the plug when called away from the ironing board. Never pull the plug out by the cord; always grip it at the spring. Always replace at once frayed wires--as the ends often collide and make blow-outs. Don’t leave your electric curling iron on the table cloth and do something else about the room without first turning off the current--or you’ll have a cute little fire. Care must be taken in using too many cluster plugs, because the electric circuit (path) may be overloaded. That is, too much electricity drawn over the wire which is made for a certain load. Then your fuse will blow out. Extra appliances should be attached to different circuits. This a good electrician will regulate for you. Too much wattage (horsepower) over one circuit is like forcing any machinery to the breaking point. A percolator, toaster and a lamp are too heavy a load for the ordinary circuit. Connect at the same place only those appliances that are of low wattage.
