Question

Grounding jumpers used on a transmission or distribution circuit must be ? .

a.insulated to the values of the line on which they are being applied
b.made up of a four-conductor set of tinned copper leads with alligator clipends
c.no larger than 4 AWG copper four-conductor
d.of a size capable of conducting the maximum fault current for the time necessary to clear the fault

Answer 1

Grounding jumpers used on a transmission or distribution circuit must be of a size capable of conducting the maximum fault current for the time necessary to clear the fault.

Step-by-step explanation:

Grounding jumpers used on a transmission or distribution circuit must be of a size capable of conducting the maximum fault current for the time necessary to clear the fault. This is because the purpose of grounding jumpers is to provide a low impedance path for fault currents to flow, ensuring that the fault is quickly detected and cleared.

If the grounding jumpers are not capable of conducting the maximum fault current, they may heat up and become damaged, which can delay the clearance of the fault and potentially cause further damage to the system.
