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.

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: 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!
Red: Hot: An
ungrounded current carrying conductor in 120/240 volt systems. Do not touch!
You will get zapped!
