Electrical Wiring Color Chart
After 30 years in the electrical industry I know these colors with out thinking about them while
wiring a electrical panel.Most seasoned electricans know this as
well;however I still run accross journeymen and apprentices that struggle with getting the colors correct.It sucks
when you go to make up a panel and ckt 32 was pulled in blue and 30 was blk.It makes the panel look like someone
screwed up the correct phaseing related to neturals.
I highlighted "most" because I know people that have been our industry for 10 years and still can't
mark the wires correct!!
I have had many electricians ask how I know which color matches which number-and this is what
I show them.
If your an electrical contractor or a apprentice electrician you can copy and print these
Hang them up while wiring a panel for quick reference.
Down size them and laminate for use next to a wire cart.
Note that these are for Commercial applications.Residential charts vary due to the amount of three
wire home runs you have.
