EARTHING AND BONDING

What is the primary objective of earthing in electrical systems?

• To connect conductive parts to ensure they are at the same electrical potential

• To prevent the build-up of static electricity

• To improve the efficiency of electrical appliances

• To provide a direct path for electrical currents to flow into the ground

Which component is NOT part of an effective earthing system?

• Earth Electrode

• Earthing Conductor

• Main Bonding Jumper

• Equipotential Bonding

What is the purpose of bonding in electrical installations?

• To direct fault currents into the ground

• To ensure all conductive parts are at the same electrical potential

• To generate electrical power

• To increase the electrical resistance of the system

Which of the following is a key component of a bonding system?

• Earth Electrode

• Main Earthing Terminal

• Bonding Conductors

• Insulation Breakdown Detector

What is the main difference between earthing and bonding?

• Earthing is for connecting to the ground, while bonding is for connecting conductive parts together

• Bonding is only used in residential buildings, while earthing is used in commercial buildings

• Earthing uses copper conductors, while bonding uses aluminium

• There is no difference; they are interchangeable terms

Why is earthing important for safety?

• It provides a path for fault currents to dissipate into the ground

• It makes the electrical system more efficient

• It reduces the cost of electrical maintenance

• It increases the voltage to safe levels

What does supplementary bonding connect?

• Different earth electrodes together

• Specific metallic components, such as water and gas pipes, to eliminate potential differences

• Metallic components to the main distribution board

• The electrical installation directly to the power source

How can you tell if your house has the correct earthing and bonding?

• By measuring the voltage in your outlets

• By inspecting for visible earthing components and verifying equipotential bonding

• By the age of the house

• By checking the color of the wires

What should you do if you're unsure about the earthing and bonding in your house?

• Hire a licensed electrician to conduct a thorough inspection

• Try to fix it yourself using online tutorials

• Check online forums for advice

• Ignore it as it's not important
