Electrical Exam Term
Bonding
The permanent joining of metallic parts to form an electrically conductive path that ensures electrical continuity and safely conducts fault current.
Detailed Explanation
Bonding is different from grounding. While grounding connects to the earth, bonding connects metallic components together to eliminate voltage differences between them. NEC Article 250 covers bonding requirements. Common bonding applications include water pipes, gas pipes, structural steel, and equipment enclosures. The main bonding jumper connects the grounded conductor to the equipment grounding conductor at the service.
