Protective conductors (PE) must be sized either by:

The latest version (SS 551:2022) replaced the 2009 edition with several critical additions: ss 551 code of practice for earthing

By limiting the "step" and "touch" voltages during a fault, it prevents fatal electric shocks to personnel. Protective conductors (PE) must be sized either by:

The primary objective of SS 551 is to ensure that all conductive parts of an electrical installation are connected to the general mass of earth. This creates a low-resistance path for fault currents, achieving three main goals: achieving three main goals:
