RE: Lightning Protection Conductor Sizing
can I see nfpa780 and im not sure of the #2/0 awg? what does this mean. I am used to 37/2.03(120 sq mm) conductor size notation. Your assistance is greatly appreciated.
RE: Lightning Protection Conductor Sizing
AWG (American Wire Gauge) is the English/US wire size designation. See http://www.aseapower.com/technotes/tn_004.htm
NFPA specifies the stranding no/size as well, which you may not be able to match in Australia.

For additional references, consult the NFPA - 780, NFPA- 78 and Tables 4-4.3 A & B in the proposed NFPA 781 document enclosed.
