nope.you can use both the armour and a core for cpc. only difference being that if you only earth the armour at the supply end, (to comply with earthing it), it won't be part of the cpc for the circuit.yes, and obviously the resistivity of copper/steel is different so using the armouring as cpc aswell as a copper conductor is not advisable

Why not?really? both connected together?
Not got the idea yet? OPAt the fault current you will be looking at, the armour and the internal CPC can most likely handle the fault current individually, so connecting them together is really no issue.
As said already just bond the supply end then it won't act in parallel with the internal cpc if you don't want it toI know armouring is ok as cpc on its own but I didn't know you could use both armouring and a core as a joint cpc
Earth rather than bond! No reason not to parallel them though.As said already just bond the supply end then it won't act in parallel with the internal cpc if you don't want it to
It's like being told of by the headmasterEarth rather than bond! No reason not to parallel them though.
only if you want to make the cooker TT.Question is, why wouldn't you parallel them up?
It's not always an option in every case.Question is, why wouldn't you parallel them up?
