Color Codes
Wiring Color Codes: If you look
at any wiring you will see that the wires are all different colors.
This is so an electrician knows what they are looking at.
Each color has a specific function.
Direct Current Color Codes: ABYC E-11 Table XIV & Table XV.

Alternating Current: Wiring Color Codes
I strongly recommend that unless you have experience or training working with AC electrical systems, that you hire an electrician. AC is deadly!
Black: Hot: An ungrounded current carrying conductor. This is the hot side of the system. Do not touch! You will get zapped!
White: Hot: Shore Grounded Neutral A current
carrying conductor maintained at ground (Earth) potential. Do not
touch! You will get zapped!
Green or Green with Yellow Stripe: Grounding Conductor.
Used as a path to ground if there is a ground fault in the system. Do
not cut or disconnect! Normally does not have any current. If there is
current in the green wire there
is something wrong.
Red: Hot:
An ungrounded current carrying conductor in 120/240 volt systems. Do
not touch! You will get zapped!
