History of Wiring Codes
The Electrical Appliances (Color Code) Regulations 1969 came into effect on 1 July 1969. This regulation ensured that a set of rules and an industrial color code pattern must be followed worldwide.
This included four major color codes for industry as well as for domestic purposes:-
- Brown for live – Live wire means that the wire is connected to the main supply. So, brown color was used indicating this property of the wire.
- Blue for neutral – Neutral wire shows the returning path of the current from appliance to source. Sp, blue was used to indicate this property.
- Green for Earth – Earth wire means a safety wire that protects the appliance from electrical shocks. So, green color was used for this purpose.
- Yellow for Earth – Yellow wire is used for the high voltage for lights, fans. Also it is used for safety so that current of live wire can not pass directly to casing.
