Black/red/blue might be typically used for 120/208 rather than 277/480, but I don't think such use actually violates any article of the NEC.
I realize the use of black,red,blue for 277v does not nessecarly violate any code,but if 120v is already in the box and identified as black,red,blue, then using black,red,blue for 277v would be a violation
Randy said that, "I wonder how big of a "C" clamp they used to get the blank on in the first place!" In the first picture it sure does look like they did! See the hole in the wall underneath the box???
