I was at lowes the other week, and a customer of theirs was buying wire to install a service, he was looking at the 3-conductor URD and wanted to know how to tell the conductors apart, was there any special way to mark them and if they had to go into the meter base in any special manner. And the clerk told him No.
Tom is right on, these people are instructing non-trades people on how to do services or any other type of wiring and themselves dont even have a clue.
Then the inspectors come out and gig the job and have to explain how to do the job right.
Are they really saving money by doing it themselves ??????????
