Wiring Method References ?

[acestu]

Hi Fellas, i was wondering if you could help me please, if i have twin and earth run in trunking this is reference method B, but if it is in trunking and in the wall under plaster and capping aswell, then what would the reference method be ie 2 different methods, are they both listed ?

thanks in advance

Hi Acestu

Your reference method would be B,C. for your installation as described above.

B for in trunking Horizontal
C for in trunking Vertical
C for for direct in masonry inc sheathing

Hi Electro, so am i right in thinking that if your circuit uses all three methods you would put B,C,C, or would you just put B,C, because two methods have the same number....

thanks

I suppose you could put CCBBCBCBBC for every part of the entire run from board to outlet but BC would suffice
