eli5 how is a neutral and earth able to use the same wire (PME) in electricity distribution? (In the UK)
In: 6
They are both at the same potential. Splitting them up allows for additional fault-checks and safety features, none of which are strictly necessery for function.
The biggest benefit of the split is a controlled current path that returns through neutral. Otherwise earthed metal objects could be part of the return path, which can heat them up.
