Here is the link directly to the abbreviations. I noticed CCC is not in there- soon to be corrected-- It is current carrying conductor.

And no EMT.
Slightly more seriously, a lot of local jargon gets used here.
I have no problem with that considering the basis of the forum.

If I don't what something means I can, and do, ask.
Members here have been patient and polite in explaining things for me.
And I greatly appreciate that.

EMT and THHN do not need to be in the list - they are trade names more so than an abbreviation and are more universally accepted, and have been for years. Abbreviations like EGC, GEC, MWBC, CCC are more specifically used in places like this forum.
 
BTW- if you seriously would like to add some more please send them to me with the answer key- I may not know. I think the emt was a joke....

Wasn't intended as a joke. It's an abbreviation I've seen here ad had it explained.
Electrical metallic tubing.
And, as it's descriptive, I wouldn't have thought would be a trade name.

Similarly with THHN.
"THHN Wire stands for Thermoplastic High Heat-resistant Nylon coated."
Again descriptive.

Those terms are in the NEC but I could add a few-- If I did THHN I would have to do all insulations and that gets a bit much. Maybe I could work on a link that does the wire insulation on it's own page. The trouble is figuring out what they all stand for. I will give it a shot.

I didn't mean to put you to a lot of trouble.
Being a foreigner, I regularly come across terms and abbreviations here that are unfamiliar to me.
As I said, I can ask.

Trade names and slang are worse.
