What is the function of a main bonding jumper?

• A. To connect light fixtures
• B. To securely hold electrical panels
• C. To connect the grounding and bonding systems
• D. To reduce voltage drop

Answer: (C)

The main bonding jumper plays a crucial role in the electrical system by connecting the grounding and bonding systems. This connection is essential for ensuring that all parts of the system are at the same electrical potential and provides a path for fault currents to safely return to the ground. By properly bonding the neutral conductor to the grounding electrodes, the main bonding jumper helps prevent dangerous stray voltage and ensures that protective devices, like circuit breakers, operate effectively during fault conditions. This function is vital for maintaining electrical system safety and performance. It helps to prevent shock hazards and facilitates the proper operation of overcurrent devices, ensuring that faults do not cause equipment damage or pose risks to personnel. The integrity of this bonding system is fundamental for compliance with electrical codes and standards, promoting overall safety in electrical installations.
