True or False: Grounding conductors and bonding jumpers can be connected using machine screw type fasteners.

The statement regarding whether grounding conductors and bonding jumpers can be connected using machine screw type fasteners is indeed false. Grounding conductors and bonding jumpers are critical components in electrical systems designed to ensure safety by providing a low-resistance path for fault current. According to the National Electrical Code (NEC) and standard electrical practices, they must be connected using hardware that can provide a reliable and secure connection.

Typically, the preferred connection for grounding systems involves using terminal screws or other secure fastening methods that meet specific UL standards. Machine screw type fasteners may not provide the necessary integrity for grounding connections due to potential loosening over time or insufficient contact surface area, which could increase resistance. The use of appropriate connection methods is crucial to maintain system effectiveness and safety.

In contrast, the other choices reference scenarios that don't directly address the requirements or could imply varying degrees of adherence to code, which underscores the importance of maintaining clarity on proper methods for grounding and bonding practices. The clear stance presented in the question emphasizes adherence to established electrical code guidance regarding fastener types for grounding connections.
