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.

What is the definition of earthing and how it works?
ELDB stands for Earth Leakage Detection and Breaker. It is a device used in electrical systems to detect any leakage of current to the earth, which could be potentially dangerous. When a leakage is detected, the ELDB will trip the circuit breaker to cut off the power supply and prevent any electrical accidents. This is especially important in ensuring the safety of individuals and protecting electrical equipment from damage.

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)
Earth leakage circuit breakers can trip in the off position if there is a fault in the wiring or if the breaker itself is faulty. It could be due to high levels of leakage current or a short circuit. It is a safety feature to prevent electrical hazards and should be investigated by a qualified electrician.
Earth leakage, also known as ground fault, occurs when an electrical current flows through an unintended path to the ground. This can happen due to malfunctioning electrical equipment, damaged insulation on wires, or moisture entering the electrical system. The flow of current to the ground can pose a risk of electric shock or fire, which is why it is important to have proper grounding and insulation in place to prevent earth leakage.
