The bonding jumper provides a reliable conductor to ensure what?

• A. Electrical conductivity between metal parts required to be electrically connected
• B. Electrical isolation of metal parts
• C. Ground fault protection at all times
• D. Voltage regulation across circuits

Answer: (A)

Bonding keeps metal parts that must be connected at the same electrical potential by using a low-impedance conductor. This minimizes dangerous voltage differences between surfaces you might touch, reducing shock risk. It also provides a reliable path for fault current so protective devices can trip, helping safety. It’s not about isolating metal parts, it doesn’t alone guarantee ground-fault protection, and it doesn’t regulate voltage across circuits.
