What to do to Protect Your Appliances from Circuit Trip or Short Circuit?

Short circuit or tripping is the process that occurs when an electrical appliance is supplied with an over current, either by connecting the positive terminals with the negative terminals, or by the overflow of voltage and current. This is why circuit breakers and fuses are used. They protect the appliance from short circuiting. Short circuiting spoils the appliance, and cannot be used again, therefore, the damage is very high. Short circuiting usually brings about sparking in the conductors inside the appliance causing them to either burn or snap, and if the circuit breaker’s capacity is lesser than the short circuit values, the device can explode, literally!

Short Circuit

Tripping of the circuit means that the circuit has been overloaded, and a circuit breaker has affected a closure of power supply to that appliance. Tripping may be because of many varied reasons. Tripping also occurs when a circuit inside the application snaps or burns off, and that cable needs to be repaired to make the appliance work again. Short circuiting and tripping are nearly synonyms in terms of their definitions and there protections.

Protection against Short Circuits

Short circuit protection is usually very difficult to achieve because short circuits have the ability to completely break the protective device itself. Therefore, it is very crucial to choose a properly rated breaker device with proper short circuit amperage. The short circuit amperage gives the short circuit current that might pass through a device that is short circuited, and this limit plays a major factor in deciding the circuit breaker or fuse for that appliance.

Protection against Tripping

Tripping occurs more often when there is an overload, and protection is required to prevent appliances from tripping. There can be momentary overloads, which the appliance can take and needs, but the protective device that is used should not detect this as an overvoltage and break the circuit. Therefore, protective devices against tripping should be chosen very carefully. Hence, the protective device is chosen such that it can accept a sudden surge of overload, but switches off the circuit when the overload is over a long period of time. This is why circuit breakers are really important to prevent from tripping.
