Here is a better shot of the breaker box:
Thanks for the compliment and comment.
There is only one white wire that is connected to a breaker.
It is the 30 Amp 230V water heater. I know what you mean that it should be color taped because it is not a neutral. It's funny, I've seen so many installations of water heaters where electricians didn't color tape the white either. The city inspector looked at it with me there and didn't say a word about it.
I have wondered why 10-2 wire isn't manufactured with black/red/ground instead of black/white/ground? I would think most 10-2 wire that is sold is used for 230V water heaters.
