Bonding
Bonding is a crucial safety practice in electrical work where metal parts are connected together to prevent electrical hazards. Think of it as creating a safety network that connects all metal parts of a building's electrical system to ensure electricity has a safe path to the ground if something goes wrong. This is different from grounding (though they work together) - bonding connects metal parts to each other, while grounding connects to the earth. It's a fundamental safety requirement in electrical installations that protects both people and equipment from electrical shocks and fires.

Example Interview Questions
Senior Level Questions
Q: How would you plan and supervise a bonding system installation for a large commercial building?
Expected Answer: A senior electrician should explain how they would assess the building's needs, ensure code compliance, coordinate with other trades, and implement proper testing procedures. They should mention documentation, team supervision, and quality control measures.
Q: What are common issues you've encountered with bonding systems and how did you resolve them?
Expected Answer: Should discuss practical experience with troubleshooting bonding problems, such as loose connections, corrosion issues, or improper installations, and explain how they identified and fixed these issues safely.
Mid Level Questions
Q: Explain the difference between bonding and grounding to a client.
Expected Answer: Should be able to explain in simple terms that bonding connects metal parts together for safety, while grounding provides a path to earth. Should use clear examples like connecting metal pipes or electrical boxes.
Q: What safety procedures do you follow when working on bonding installations?
Expected Answer: Should describe proper lockout/tagout procedures, use of testing equipment, personal protective equipment, and following safety guidelines and regulations.
Junior Level Questions
Q: What is the purpose of bonding in electrical installations?
Expected Answer: Should explain that bonding is a safety measure that connects metal parts together to prevent electrical hazards and ensure proper current flow in case of a fault.
Q: What tools are typically used for bonding work?
Expected Answer: Should identify basic tools like wire strippers, crimping tools, multimeters, and various types of connectors used in bonding installations.
