For general electrical installations, the minimum size for a copper protective earthing (PE) conductor is often selected using a simplified relationship to the phase conductor ( Sphcap S sub p h end-sub ), provided both are made of the same material: Phase Conductor Size ( Sphcap S sub p h end-sub Minimum Earth Conductor Size ( SPEcap S sub cap P cap E end-sub Same as Phase ( Sphcap S sub p h end-sub Half of Phase ( This guide provides a comprehensive and explains how
