Besides the age and the double tap on the main, the EGCs and Neutrals together in the sub panel. The knock outs missing and the cable on the sub missing the clamp coming into the sub panel. And yes it had pointed screws that came with this little jewel. Am I missing anything?
The main panel is mounted outside on the north side of the house and the sub-panel is located in the garage on the opposite side. As you can see the main disconnect is 100 amps/Zinsco. The double tap that is coming out of there is going to the AC compressor that is right nest to it. This feeds the sub-panel that is on the opposite side of the garage.
