What type of bonding is used to ensure that exposed metal parts do not become live and create a potential shock hazard?

• Equipotential bonding

• Supplementary bonding

• Cross bonding

• Temporary continuity bonding

Which type of bonding is typically used for connecting together the metal parts of different electrical installations to maintain the same electrical potential?

• Equipotential bonding

• Supplementary bonding

• Cross bonding

• Temporary continuity bonding

What is the purpose of temporary continuity bonding?

• To provide a permanent electrical connection between metal parts

• To ensure that metal parts are at the same electrical potential only during maintenance

• To connect metal parts of electrical installations from different buildings

• To reduce the risk of electric shock during normal operation of electrical equipment

What is the main purpose of supplementary bonding?

• To connect metal parts that are not normally live but can become live in fault conditions

• To temporarily connect metal parts during construction

• To permanently connect metal parts in different rooms

• To replace the main earthing system

What must all metal parts within the building be joined to for equipotential bonding?

• The main water pipe

• The earth cable

• The electrical meter

• The gas line

Which services need to be bonded to the building's electrical system for equipotential bonding?

• Oil, gas, and water only

• Gas, electricity, and water only

• Oil, gas, water, and electricity

• Electricity and water only

What is the purpose of equipotential bonding?

• To prevent the electrical meter from overloading

• To ensure equal potential between metal parts

• To reduce the cost of electrical installation

• To increase the efficiency of electrical appliances

What size is the earth cable used in equipotential bonding?

• 5mm²

• 10mm²

• 15mm²

• 20mm²

What happens if a fault occurs in a building with equipotential bonding?

• The electrical current bypasses the building completely

• The electrical current causes a fire

• The electrical current has a direct route through the wiring, stopping a person from getting a shock

• The electrical current damages the building's electrical appliances

What is the size of the cable used for equipotential bonding in the electrical tasks diagram?

• 5mm² cable

• 10mm² cable

• 15mm² cable

• 20mm² cable
