Title: Module 2: Wire Colors
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 2: Wiring

Introduction

In the following video, we will discuss some of the wires we will be using in future labs.

Please use the following list to differentiate what wires to use and not to use in your labs.

=Use in our labs

=Do not use in our labs (but you will see it in the industry)

AC Wires

- AC Hot: black or red (industry standard)
- AC Neutral: white (NEC standard)
- AC Ground: green or bare copper (NEC standard).

 | Note |
 | For our labs, we will always use green for ground. However, you will see that the Romex only has bare copper for ground. |

DC Wires

- DC +
  - brown  (European standard)
- DC -
  - blue (European standard)
- DC +
  - red (USA standard for external wiring)
- DC -
  - black (USA standard for external wiring)
- DC +
  - blue with a white stripe (USA standard in control panels)
- DC -
  - white with a blue stripe  (USA standard in control panels)

 | Note |
 | Brown for DC + and blue for DC - (the European standard) is a standard for many sensors as well. That is why we follow this in our labs. |
