Different codes are popular in different areas. However, these high-leg delta systems are uncommon with newer installations. Self-laminating wire wraps and heat-shrink tubes are available to create clean, professional labels for your project. Not all wire color codes are the same, though, and some even contradict each other. This standard provides a consistent approach that can be applied to many different kinds of connections over time.

In these cases, color coding should be added during installation, using colored bands that wrap around the wire.
