143 S15 Bonding

What is the primary definition of bonding?

• a) Connecting wires to a power source
• b) The permanent joining of metallic parts to form an electrically conductive path
• c) Separating electrical circuits
• d) Insulating electrical components

What is the main purpose of bonding?

• a) To increase electrical resistance
• b) To form a non-conductive path
• c) To ensure electrical continuity and safety
• d) To disconnect circuits

What is the first main reason for bonding?

• a) To reduce power consumption
• b) For personal safety
• c) To increase voltage
• d) For aesthetic purposes

How does bonding prevent electric shock?

• a) By increasing resistance
• b) By disconnecting the power supply
• c) By making a very large current flow that triggers overcurrent protection devices
• d) By using non-conductive materials

What is the second main reason for bonding?

• a) To save energy
• b) To prevent fire or explosion
• c) To increase current flow
• d) To decrease electrical potential

What environments are at higher risk of sparks or static buildup?

• a) Residential areas
• b) Agricultural fields
• c) Oil or chemical industry
• d) Educational institutions

What effect does bonding have on electrical potential between parts?

• a) Increases potential difference
• b) Allows current flow between parts
• c) Ensures the same potential, preventing current flow
• d) Disconnects all parts

Which items may need to be bonded in an installation?

• a) Only electrical cables
• b) All metallic items like pipework, equipment casings, and cable containment
• c) Plastic components
• d) Wooden structures

What is the primary benefit of bonding?

• a) Increasing electrical potential
• b) Reducing current flow and preventing electrical shock
• c) Enhancing current flow
• d) Decreasing system efficiency

What does bonding not protect against by itself?

• a) Electric shock
• b) Electrical energy build-up
• c) Fire
• d) Physical damage
