If a bonding continuity test shows high resistance, what does this indicate?

Explanation:
Bonding continuity tests check that protective bonding conductors form a continuous, low-impedance path to earth so fault current can flow and trip protective devices quickly. If the reading is high, the bonding path isn’t effectively continuous, meaning there’s a fault or poor connection somewhere in the bonding circuit (such as a broken conductor, loose terminal, corrosion, or a damaged strap). This compromises the ability to carry fault current to earth, posing a shock risk. It doesn’t indicate an insulation fault or a general loose live connection, and it isn’t a signal that there’s “no problem.”
