How do you annotate/mark wires in the same circuit?

Is there any convention employed by the pros as far as identifying, tagging, annotation wires in the same circuit appearing twice in the same conduit?

For example I have a hot wire from circuit 7 coming into the box. The wire than runs to another box to a switch and back through the same rigid conduit. So how I have three wires in this box from circuit 7. Is there any sort of convention to mark it so I know which wire is GOING TO the switch and which wire is COMING from the switch?

Some would use a different color for the switched hot. A tape wrap could work also.


Answers based on the National Electrical Code. Local amendments may apply. Check with your local building officials.

You can use the coloured tape simauir what the Chicago codes been using for a quite a while.

Grey-Dedicated neutral for GFCI
red-black -blue--Power
Brown--travelers for three way
purple--GFCI protected power
yellow-orange---switch legs
Note : you may want to modifed the listing if you have AFCI circuits so subuite or make a double stripe tape to indentify a AFCI protected verison.

The answer will be based on NEC ( National Electrical code ) or CEC ( Cananda Electrical code ) or ECF ( Electrique Code France )
