Protective conductor cross-sectional area should be at least 4mm² for copper wire. Minimum size for single equipment grounding conductor is 4 AWG copper. Typical earth continuity conductor size is 3 SWG (32mm²)
Single line diagram serves as blueprint for electrical system analysis. Essential for testing, service and maintenance activities. Provides snapshot of facility at specific moment in time. Must be updated as facility changes occur
Electrical current flows through metal wires with negative (hot) and positive (neutral) charges. Electricity seeks to return electrons to ground through neutral wires. Faulty wiring can cause hot current to stray through metal or insulation
Proper earthing is crucial for safe operation of diesel generators. It provides low-resistance path for fault current to ground. Protects operators from fatal electric shocks. Ensures safe discharge of fault current to prevent equipment damage. Helps prevent electrical fires by dissipating fault heat
Earthing system protects people and equipment from dangerous voltages. Provides low resistance path for earth faults within plant. Prevents dangerous ground potential rises for remote generation. Reduces electrical noise for electronic systems
