High leg marking

[Jim1959]

The national industry norm is to mark it orange, or use orange wire for #6 and smaller. The context of other wire colors usually distinguishes it from the B-phase in a 480V system. SF has a local requirement for marking it violet.


If you deviate from the industry norm, it needs to be explained on the equipment itself. Textual wire tags, permanent equipment cover labels, or anything else. Anything you can do to make the high leg as vivid as possible is encouraged.
