Final answer:
The equipment bonding jumper in a separately derived system connects the system housing to the neutral bus bar to provide a low-resistance path for electrical faults and protect personnel and equipment.
Step-by-step explanation:
The equipment bonding jumper in a separately derived system connects the system housing to the neutral bus bar.
The purpose of this bonding jumper is to provide a low-resistance path for electrical faults in order to protect personnel and equipment. By connecting the system housing to the neutral bus bar, it ensures that any fault currents are safely diverted to the grounding system.
For example, if there is a fault in the system and the electrical current inadvertently flows through the system housing, the bonding jumper ensures that the current is redirected to the grounding system rather than causing potential harm to people or equipment.
