• Ring Main Circuit connects numerous electrical outlets in a loop supplying each outlet with 13 amps of power. The electricity flows in both ways so if one outlet fails, the electricity will just flow the opposite direction keeping the rest in power.

  Junction Box is the centre point of where all the wires meet.

  Consumer Unit allows user to turn On, Off and Reset the power. It also contains Fuses and Circuit Breaker.

• Miniature Circuit Breakers (MCBs) are to trip when there is an overload in a circuit.

  
• Residual Current Devices(RCD) cuts off when there is an imbalance in the current on the circuit to prevent electrical shock. It looks for a leakage more than 30 milliamps to cut off.

  
• Grounding the circuit leads the current to the ground, which is the earth. The leakage flows through the conductor then through the rod
