1. SHORT CIRCUIT
A low-resistance-connection established by accident or intention between two points in an electric circuit.
Short circuit happens when a hot wire touches a neutral or ground wire, the extra current flows through the circuit causes the breaker to trip or fuse to blow.
2. FUSE
-A type of overcurrent protection device.
Is an essential part of a power distribution system to prevent fire or damage.
Current flowing through a wire heats the wire. The length of a wire affects its resistance, which determines how much current flows in the wire and how hot the wire gets.
3. CIRCUIT BREAKERS
An incredibly simple solution to a potentially deadly problem.
CIRCUIT BREAKERS WORK
A metal wire or strip melts when too much current flows, which breaks the circuit in which it is connected.
4. OVERLOAD IN A CIRCUIT
In electricity supply, overcurrent or excess current is a situation where a larger than intended electric current exists through a conductor - leading to excessive generation of heat and the risk of damaging infrastructure and equipment and causing fires. Possible causes for overcurrent include short circuits, excessive load and incorrect design. Fuses, circuit breakers, temperature sensors and current limiters are commonly used protection mechanisms to control the risks of overcurrent.
5. ELECTRICAL DEVICES OPERATING AT ONE TIME OF TEN BLOW A FUSE
This happens when there are many consumers of devices. This is because of overcurrent or excess current where a larger than intended electric current exists through a conductor leading to excessive generation of heat and the risk of damaging infrastructure and equipment and causing fires.
6. DANGERS OF SHORT CIRCUIT AND
OVERLOAD
People may die because of short circuit and overload. We must be careful when operating a device. Carelessness can lead to fire, electrocution and even death. Observe extra care in using appliances. Large amount of current passing through a person can kill.
