– Using gas or water pipes as earth electrodes.
To ensure adherence to SS 551:
: Rods, plates, or mats buried in the soil to provide a low-resistance path to the ground.
Maintenance teams must routinely inspect the MET, bonding clamps, and exposed joints for signs of galvanic corrosion or loose terminations, which can severely compromise the system's continuity. Conclusion
is critical. SS 551 prohibits the use of aluminium or unprotected steel in direct contact with soil.
: Details the specific interface requirements between Low Voltage (LV) and High Voltage (HV) substations within buildings.
Architects and electrical engineers must bond incoming metal services (water mains, gas pipes, structural steel frames, and central air conditioning ducts) to the MET using heavy-duty copper conductors near their point of entry into the building.
