What fuse should be used if the appliance has 240V and 1600W? Note: please use the proper formula, refer to the given lesson.
Fuse: Invented For Safety What happens when too much current pass through a wire? Well, that could be a big problem because you do not want to lose everything by a fire. Most common fire events happen because of the so-called "faulty-electrical wiring". We can prevent such hazard with the help of the fuse. A fuse is an electrical safety device that protects the circuit by removing electrical current from it when the current in the electrical circuit becomes unbearable. The fuse has a piece of wire that easily melts. If that piece of wire melts, the circuit breaks. What Is A Fuse Rating? A fuse rating is the current needed to break the fuse. All fuses have a rated value or fuse rating. It indicates the maximum current that the fuse can bear before it blows. The electrical appliance draws current under normal working conditions. The fuse should be chosen at a rating slightly higher than this current. f the calculated fuse rating is 4.25, we have to choose 5 A fuse. Common fuse rating: 1A, 2A, 3A, 5A, 10A, 13A, 15A and 30A. How To Calculate The Fuse Rating Using the guideline at the normal operating current Therefore: Thus: In units, Power (Watts) = Current (A) x Voltage (V) Current = Power/Voltage Fuse rating (A) = (Power/Voltage) Fuse rating = (watts (W)) /volts (V) ) Fuse rating = Ampere (A) Fuse Rating Calculations 1. Calculate the fuse to be used if power rating of a vacuum cleaner is 800 watts. In the Philippines, the voltage rating ranges from 220 to 240 V. let us use the maximum amount because we need to find the current that can blow a fuse. Solution: Fuse rating = Power/Voltage Fuse rating = (800 W /240 V) Fuse rating = 3.33 A 2. What is the fuse rating of a 5000W- clothes dryer ? Solution: 5 A fuse should be used. Fuse rating = Power/Voltage Fuse rating = (5000 W/240 V) Fuse rating = 20.83 A Next fuse up is a 30 A fuse, the fuse rating must be 30 A fuse.
