Nice pictures, I can enlarge em way up without getting too grainy.
These things look more like push rod tubes than anything that belongs in a breaker panel. Ya got what, four of them in there that I can see. I wonder what the condition of the wiring inside the tubes is.
One potential problem I see is the over bending of the cable/wiring at the end of the tubes. What keeps the tube ends from wearing / cutting into the insulation (besides the electrical tape)?
Another thing is that in a panel, pretty much all metal surfaces are either live or grounded. These tubes are an exception.
There are 10 types of people. Those who know binary, and those who don't.
