Marking Single Phase Conductors

[Amp Dr]

What would be the purpose of marking the SE conductors for a 120/240V single phase service?
I see some installs where the conductors are marked/taped blue & red. I don't understand why!

No, its not required. It's just a common practice. It would only be required when there was a high leg but that would only be on a 3 phase delta.

Just something to do out of habit, personal preference or job spec.

Or someone likes pretty colors...

I do it out of habit because we run so many single phase parallel services

even SE cable.. it’s just habit

The cable is actually already marked, if you look closely, there usually is a red stripe on one of the conductors.
