The following are key installation requirements: Grounding Conductors: Generally, 40mm × 4mm galvanized flat steel should be used for grounding conductors. Galvanized steel is preferred for its excellent conductivity and corrosion resistance, ensuring a long-lasting grounding system.
The following are the key grounding resistance requirements for different components: Large Grounding Short Circuit Current Systems: The grounding resistance should not exceed 0.5 ohms. This is crucial for systems with high fault currents, where low resistance ensures efficient dissipation of energy.
The equipment shall be constructed, wired and tested to the following standards: Standard 32-1972: Requirements, Terminology, and Test Procedure for Neutral. Standard 142-1991: Grounding of Industrial and Commercial Power Systems. 3.0 NEUTRAL GROUNDING RESISTOR
