i agree. if the single cpc can withstand the pefc, then a C3.Use the adiabatic equation to confirm whether or not the single cpc size is adequate. If so, no code, but noted. If not, C2.
C2 generally, something's wrong somewhere....may be C3 noted, depending on circumstances
Why a C3? We run ring final circuits in steel conduit and use that as a single earth.
Where is the reg that says r2 must be a ring?
