I am sitting my 2330 L3 rig next week, one circuit is in MI, the imformation supplied states for that circuit, under wiring conductors ( as in the Schedule of Test Results) they are Live/CPC as 1mm and sheath.
I have no idea what to write down for the CPC 'mm' size.
any advise will be great,

:)

Hey.

With regard to the swa, I always put "K" in the CSA box as this refers to the value of armouring CSA given in the book.

IGNORE THE TABLE NUMBERS, IT'S AN OLD REFERENCE^^^^^^^

The values in GREEN comply with BS7671, the values in RED do not

With these values you can then use the adiabatic equation P128 BS7671 to double check conformity

Hope this helps.
