Yes just some scrap wire I had around that I used for my tankless water heater used a white wire for a ground.
3. The 200A CB is marked as Service Disconnect, but it is served by a 4-wire cable.
Came with that sticker did not know it was a code violation. Panel is a sub main is 100' away in the garage.
4. There appear to be circuit breakers that are not Siemens in the panel.
All murray breakers in a murray/siemens panel
5. Depending on the wire size, the 8 red/black cables may be overfused and/or exceed the conduit fill limits.
#6 on a 40 amp breaker total 9 #6 wires in 1-1/4" conduit not over fused or over conduit fill. Actual draw on wires is about 30 amps each.

I just used the scrap wire for the tankless water heater till I got something else but I just left it there for now. It's on my list along with straightening out the panel.

Thanks for the feedback. I wouldn't stay up nights worrying about the scrap wire if it's only going a few to the water heater. I would definitely color that white wire green ASAP, although that is also technically a violation since it is smaller than #4.
