Electrical drawing Abbreviation and Acronym

Hi all,
I read the IRC5 electrical drawing but so many abbreviations, anyone have the Abbreviation explanation of this Drawing.
Many thanks.

There is a page near the front that explains the symbols (attached for reference).

Yes, Graemepaulin
However, many abbreviation words in drawing. I not mention to symbols.
Thanks,

Any particular abbreviations causing problems? I realize a complete list would be better, but perhaps a few could get you started.
