Thanks for the comments. I realize this was posted many months ago originally.

Thanks to Joe for re-posting it. I just happened to browse the forum.

Walrus:
Apparently I believed that a grounded conductor should not have been taped black, perhaps thinking that this re-identified it. I figured, either tape it white, or leave it bare.
The feeder conductors: I just didn't like the look of it, but, I suppose a little extra conductor couldn't hurt.
I was incorrect in believing that a 20-amp circuit had to have 20-amp devices on it. I have been studying the NEC, and now know better.

Sierra Electrician:
Yes, this was the first time that I had looked in the panel. I moved into the house with my mother at the age of 14, before I knew anything about electricity. My mom moved out, and I purchased the house a few years ago. Of course, now, I have a clue, and any house I buy will be checked.
Yes, the house is an electrical bad dream, maybe not quite a nightmare! HaHa!
Inspected??? That's what I thought. This house was added on to about 1980, and I wondered how it passed myself. Maybe only the "new" wiring was inspected???

Pauluk:
It seemed odd that the receptacle at the front of the house would be on the same circuit as a bedroom at the back of the house, but I now realize that this is not a violation of NEC. It just went with the fact that the livingroom, master bedroom, bathroom, and one duplex receptacle are on the same circuit. (this in the "new" part of the house).

I have added an equipment grounding conductor terminal bar to eliminate the split-bolt, and a main bonding jumper between it and the neutral bar. I also have removed the bell transformer. Among other improvements, I can send updated pic.

Is it common for this type CH panel to not be furnished with an EGC terminal bar???
Are the "grounds" and "neutrals" intended to go under the same screw???
There are 16 slots for SP breakers, and 16 or 17 holes in the neutral bar.

Thanks everyone for the comments, give me more. I have an AOS degree in Electromechanical Systems Mechanics, specializing in automated machinery and controls. I work as a technician/electrician/mechanic in a meat packaging plant. I am learning residential wiring, and studying the NEC, I have a 2002, and a 2005 Handbook.
