Which of the following statements accurately reflects bonding requirements?

The correct statement regarding bonding requirements is that only metal raceways need to be bonded. This is based on the National Electrical Code (NEC) requirements, which specify that metallic raceways, such as conduit or raceway systems, must be bonded to ensure they have a continuous electrical connection to the ground. This is essential for safety reasons, as it helps prevent electrical shock hazards and allows for the effective operation of protective devices, such as circuit breakers and fuses, in the event of a fault.

In contrast, non-metallic raceways, such as those made from PVC or other plastics, do not require bonding because they do not conduct electricity. Therefore, they do not present the same potential hazards as metal raceways. Bonding is not optional for plastic raceways since they do not need to be bonded at all.

Additionally, bonding requirements apply universally to new installations, not just existing ones, aligning with the concept of maintaining safety standards in all electrical installations. This helps ensure that the electrical system is safe and compliant with current standards, regardless of the age of the installation.
