I am doing a bit of research for a Canadian rule on bonding conductor sizing.

NEC article 250.122 B says bonding wire (equipment ground) must increase with current carrying wires per some ratio.

I have some older references to 250.95 from soares book on grounding and the green book which must be in a code older than 2002.

Anyone have an older book that has an article or table 250.95?
What did it say? Was there a Table associated with it?
