Prep boundary
Direct answer
Why are normally non-current-carrying metal parts bonded is a TradeCert Prep study concept connected to Journeyman Electrician Practice Test prep, not a copied official exam item. Bonding joins conductive parts so fault current has an effective return path that supports operation of protective devices. Always verify licensing, certification, and testing rules with the current official candidate bulletin, state manual, code book, or testing provider before relying on a detail for compliance.
