Welcome, Zappy!
If you stick around, you'll turn from a "green" apprentice into a "whatever color electricians turn" one much faster than the fellows that don't pay much attention.
I learn things all the time from the greenest of guys, and I started the trade in '70. My learning curve took an abrupt spike in 2000, when I came here.
Please feel free to ask anything trade related question that you want.

The only dumb question is one that isn't asked.
