Yes, a loose neutral wire can effect the operation of Earth Leakage Circuit Breaker.
Ground / earth protection will not impact cable sizing.
there will be current that isn't carried by the current carrying conductors
Earth leakage current or ground leakage current is current going where it is not supposed to be going (whether it is on a laptop or not). Power line current should only flow between hot and neutral. The earth or ground line is only there for safety purposes to keep the metal chassis at 0V at all times.
An earth leakage relay is an electronic or electromechanical device that detects the current flowing to earth (Americans call this ground). If this earth leakage current is above a preset level (and carries on for a preset time) the relay is "tripped" - this may switch on an alarm signal - or more usually it simply disconnects the supply. Currents may flow to earth due to a fault condition or because of lots of individual items connected to the supply have a small "leakage" to earth.
The best way to stop earth leakage is to make sure that the are no active circuits going to ground. This will help keep the circuit running right.

ELDB is Earth Leakage distribution board it is used for earth fault.
What is the definition of earthing and how it works?

10mA
Earth leakage relays are instantaneous tripping relays where as earth fault relays have the option of time and ampere setting i.e. for a setted ampere the circuit breaker will be tripped off after the setted time (in second).

It's the Earth leakage resistance (Ohm)

You can test this breaker by clamping it onto the earth cable. This will provide you with the measurements that you need.
earth fault relay is similar like earth leakage ralay,but the 2nd one is more sensitiv.
