The working principle of a fuse is that it melts beforethe temperature of the conductors being protected can rise to a harmful level.

A voltage.
The fuse wire is thinner and it's designed to melt faster.

A straight 220V circuit utilizes two wires per circuit.
Yes, the wires can be reversed. You are simply completing a circuit so it makes no difference.
Insulators are used to keep electrical currents in the circuit. If they do not follow the entire circuit, it would be a "short circuit".
They are the wires through which current flows when the circuit is closed.
A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.
Think of this as two scenarios. First, we have one blub, one battery, and two wires in a closed circuit, and the bulb lights up. Next, think about what would happen if we added a couple more wires to the circuit. The bulb would still light up, just as brightly, meaning that the new wires are not increasing the amount of resistance. This means that the wires are not slowing down the flow of charges.
Neutral wires are actually ground wires. They enable the circuit to be completed.
