I have several electrical questions:

1. Is it allowable to connect 12 gauge wire to a 15amp breaker in the
service panel ?

Yes


2. How many half height single pole breakers are allowed in the main
panel rated for 200amp ?


It varies by panel and manufacturer. Check the labeling inside of the panel
or the panel cover. It will tell you exactly how many are permitted. The
maximum allowable circuit breakers (Thin or full size) in any panel is 42.



3. I noticed something very interesting in a 3-way switch arrangement
in my home. To power a receptacle, they grabbed an unswitched feed
from the light fixture by connecting a black wire to both travelers in
the box. Since there is always power on exactly one of them, this
seems to work. Is this allowable ?


LOL. I've never seen that set up before. Off hand I can't think of any code
violations, but by having the travelers connected isn't the 3-way function
disabled?



4. Is it ok to wire more than 4 receptacles downstream from a GFCI
outlet ?


Yes.


Thanks...


You're welcome.
