Fuses:

• Fuses are wires that melt when the current exceeds a certain limit due to faults like short circuits or overloads.

• The fuse wire breaks the circuit, preventing further damage.

• Fuses are stamped with their maximum current capacity.

Circuit breakers:

• Prevents fires and other safety hazards from electrical wiring faults and equipment failures.

• Similar to a fuse, except it can be reset.

• Acts like a switch, breaking the circuit if current surges.

• Often found on circuit or distribution boards in homes.

Earth leakage:

• Detects potential energy shifts in electric charge.

• Acts as a safety device to switch off electricity supply.

• Identifies current movement through earth wire, indicating a short circuit.

• Shuts down all current as a safety measure.

• Excess electrons transfer energy to the ground.

• The earth leakage is placed on the electrical distribution board.

Lightning Rod:

• Lighting is a danger to electric circuits.

• Lightning spikes are used in common lighting strike areas.

• Metal pole is connected to the house and the other end is buried in the ground.
