Although it won't help pinched insulation, above 600V, using one, two and three white bands is fairly unambiguous. Had an unbelievably cheap outfit that used 1-2-0 bands alternated with 0-1-2 bands. Two different foremen had a tiff and wouldn't talk to each other. It took ~6 months for the plant electricians to figure out what had happened. Rolled phases don’t work too well on double-ended unit substations.
