Electrical Safety Quiz

Why must gas, water, and central heating installations in domestic dwellings be bonded to the main equipotential bonding of the electrical installation?

• To prevent electric shocks

• To improve water pressure

• To reduce gas consumption

• To increase heating efficiency

What happens to the earth bonding on the pipework when a cut is made into it?

• It remains intact

• It is disconnected downstream of the cut

• It is disconnected upstream of the cut

• It becomes stronger

Why could the pipework become a lethal electric shock hazard in the event of an earth fault on the electrical system?

• Because it becomes electrified

• Because it becomes magnetized

• Because it becomes pressurized

• Because it becomes insulated

How can plumbers prevent the pipework from becoming live?

• By using temporary continuity bonding clips

• By increasing water flow

• By installing additional pipes

• By using stronger materials

What is the purpose of temporary continuity bonding clips?

• To interrupt the earth bonding on the pipework

• To improve water quality

• To increase gas pressure

• To ensure the earth bonding on the pipework is not interrupted

• 5mm2

• 10mm2

• 15mm2

• 20mm2

When should the temporary continuity bonding clips be installed?

• Before making the connection

• After making the connection

• During the connection

• At any time during the process

When can the temporary continuity bonding clips be removed?

• After making the connection

• Before making the connection

• During the connection

• At any time during the process
