Neutral Line:
1. The neutral line is a current-carrying conductor that carries the return current from the load back to the power source.
2. It is typically connected to the center tap of the transformer in a power distribution system.
3. The neutral line is designed to carry the same amount of current as the hot (live) line, but in the opposite direction.
4. The voltage on the neutral line is close to zero, as it is grounded at the transformer or at the main distribution panel.
5. The neutral line is usually colored white or gray in electrical wiring.
Earth Line (Ground):
1. The earth line, also known as the ground wire, is a safety feature that provides a path for fault currents to flow safely to the ground.
2. It is typically connected to the grounding electrode system, such as a grounding rod or water pipe, to ensure that any excess current is safely discharged into the earth.
3. The earth line does not normally carry current under normal operating conditions, but it provides a path for fault currents to prevent electric shock or fire hazards.
4. The voltage on the earth line is zero, as it is connected to the earth or ground.
5. The earth line is usually colored green or bare copper in electrical wiring.

Neutral Line
- Carries the same current as the live line but in the opposite direction.
- Maintains zero potential with respect to earth (ground).
- Provides a return path for current to flow back to the source.
- Often colored white or gray.
- Not connected to earth (ground) at the distribution board.
- Voltage between neutral and live lines is the same as the supply voltage.
- Used in single-phase and three-phase systems.
Earth Line (Ground Line)
- Carries excess or fault current to earth.
- Provides a path for current to flow safely into the ground in case of insulation failures or electrical faults.
- Protects equipment and personnel from electrical shocks.
- Often colored green or yellow with green stripes.
- Connected to earth (ground) at the main distribution board.
- Voltage between earth and live lines is zero.
- Used in three-phase systems to provide a common reference point.
Key Differences
- Purpose: Neutral line carries current, while earth line provides a safety path.
- Grounding: Neutral line is not connected to earth, while earth line is.
- Voltage: Voltage between neutral and live lines is equal to the supply voltage, while voltage between earth and live lines is zero.
- Safety: Earth line provides safety protection by diverting fault current, while neutral line does not.
- Use: Neutral line is used in both single-phase and three-phase systems, while earth line is primarily used in three-phase systems.
