Phase 1 phase 1 wiring should be brown.
High voltage wire colors.
A high voltage cable hv cable is a cable used for electric power transmission at high voltage a cable includes a conductor and insulation cables are considered to be fully insulated.
But a general color code is used to identify different types of conductors which are used in electrical wiring.
Graphic products s guide to electrical wiring colors walks you through what each of the various colors means and what the different wire color coding standards are.
It is now possible to have high voltage wiring color coded orange bright blue or even yellow.
This means that they have a full rated insulation system which will consist of insulation semi con layers and a metallic shield.
Each wire used for electrical wiring is marked with information like wire gauge ampacity maximum voltage and maximum temperature.
Due to the serious potential for deadly electrocution or other issues getting these color codes right is essential.
Some hybrid vehicles use two different colors for their high voltage electrical system on the same.
277 480 volt ac.
277 480 volt wire color standards.
These high voltage connections are quite common in many manufacturing and other industrial areas.
