What Makes a Fuse Blow
There are times when you may wonder why there is no power only in your house after having used a room heater or a blower for long hours or it could happen that only your television has stopped working all of a sudden. This could probably be because the fuse in your electrical circuit has just been blown.
Before venturing further, why don’t we learn all about fuse? A fuse is an electrical device which is designed for safety to protect the house from fire or burning. It is just a normal wire, small in size connected between electrodes and enclosed in a capsule with fire proof. This fuse helps in allowing the flow of electricity freely to the circuit. Under standard conditions the fuse will do nothing to the circuit, but when the said circuit draws higher load of current, the wire of the fuse gets heated up and eventually melts down interrupting the flow of the electricity supply.
A simple example which happens often in many of our houses is that the fuse blows away when you leave both the water geyser and a blower turned on at the same time; the power immediately trips off and this will continue even after fixing the problem by replacing the fuse. But you must understand that the problem was with the circuit which has been overloaded than its capacity. So the ideal solution is to switch off either of the appliance and use them one at a time.
Another reason of fuse blowing off could be abnormal voltage surging inside the house due to lightning or at times when there are problems with the power transmission lines resulting in the fuse blowing off. Television becomes a frequent victim to such problems and therefore it is always safe to switch off the TV and other expensive appliances in the house in instances of lightning and thunder and also during sever voltage fluctuations.
The electrician might be called for help where there is constant blowing of fuse. Nevertheless beware of not trying to solve this problem by using higher amperage fuse thinking that now the overload caused by switching on heavy load appliances could be handled. Higher amperage fuses means more electricity flowing into the circuit which can further result in an amplified damage like fire or burning in the house. So don’t venture you own skills into the job; kindly seek the help of specialists, after all safety is the key priority.
