1) EARTHING DIFFERENT? 2) L-L voltage L-P voltage? 3) earting volts 4) RCCB,MCR,MCCB, Different Between circuit breaker

Question

Accepted Answer

Earthing, L-L and L-P voltage, earthing volts, and differences between RCCB, MCR, and MCCB explained.

Earthing is the process of connecting electrical systems to the ground to prevent electric shock and protect equipment.
L-L voltage refers to the voltage between two phases of a three-phase system, while L-P voltage refers to the voltage between a phase and neutral.
Earthing volts are the voltage potential between the earth and a grounded object.
RCCB (Residual Current Circuit Breaker) is designed to disconnect the circuit when it detects a residual current, MCR (Motor Circuit Protector) protects motors from overloads and short circuits, and MCCB (Molded Case Circuit Breaker) is a type of circuit breaker that protects electrical circuits from overloads and short circuits.
Differences between circuit breakers include their design, function, and application in electrical systems.
