Elect panel code requirements
Your shop looks excellent, Mine is a tin building and it gets very cold in the winter... Your electrical panel is very neat, better than a lot of pro jobs I have seen...BUT the white wires going to the circuit breakers. If they are current carring conductors ( a feed to a 220 outlet for compressor- welder. etc) the electrical code requires they be painted/ taped some other color and the other end of the conductor at the device box also needs to be marked...Green is reserved for the ground. bare copper is ground... white is reserved for only the Neutral wire . yellow should not be used for the current conducting wire since some warehouse type lights make white and yellow hard to see which is which. the problem is that in the future someone else could get shocked touching a white wire.thinking it is a neutral wire...
